Detailed Description

represent and manipulate fields of data

vtkFieldData represents and manipulates fields of data. The model of a field is a m x n matrix of data values, where m is the number of tuples, and n is the number of components. (A tuple is a row of n components in the matrix.) The field is assumed to be composed of a set of one or more data arrays, where the data in the arrays are of different types (e.g., int, double, char, etc.), and there may be variable numbers of components in each array. Note that each data array is assumed to be "m" in length (i.e., number of tuples), which typically corresponds to the number of points or cells in a dataset. Also, each data array must have a character-string name. (This is used to manipulate data.)

There are two ways of manipulating and interfacing to fields. You can do it generically by manipulating components/tuples via a double-type data exchange, or you can do it by grabbing the arrays and manipulating them directly. The former is simpler but performs type conversion, which is bad if your data has non-castable types like (void) pointers, or you lose information as a result of the cast. The, more efficient method means managing each array in the field. Using this method you can create faster, more efficient algorithms that do not lose information.

◆ PrintSelf()

void vtkFieldData::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

Reimplemented in vtkPointData.

◆ Initialize()

virtual void vtkFieldData::Initialize ( )

virtual

Release all data but do not delete object.

Also, clear the copy flags.

Reimplemented in vtkDataSetAttributes.

◆ Allocate()

vtkTypeBool vtkFieldData::Allocate	(	vtkIdType	sz,
		vtkIdType	ext = `1000`
	)

Allocate data for each array.

Note that ext is no longer used.

◆ CopyStructure()

void vtkFieldData::CopyStructure ( vtkFieldData * )

Copy data array structure from a given field.

The same arrays will exist with the same types, but will contain nothing in the copy.

◆ AllocateArrays()

void vtkFieldData::AllocateArrays ( int num )

AllocateOfArrays actually sets the number of vtkAbstractArray pointers in the vtkFieldData object, not the number of used pointers (arrays).

Adding more arrays will cause the object to dynamically adjust the number of pointers if it needs to extend. Although AllocateArrays can be used if the number of arrays which will be added is known, it can be omitted with a small computation cost.

◆ GetNumberOfArrays()

int vtkFieldData::GetNumberOfArrays ( )

inline

Get the number of arrays of data available.

This does not include nullptr array pointers therefore after fd->AllocateArray(n); nArrays = GetNumberOfArrays() nArrays is not necessarily equal to n.

Definition at line 208 of file vtkFieldData.h.

◆ AddArray()

int vtkFieldData::AddArray ( vtkAbstractArray * array )

Add an array to the array list.

If an array with the same name already exists - then the added array will replace it. Return the index of the added array.

Reimplemented in vtkDataSetAttributes, and vtkDataSetAttributes.

◆ GetArray() [1/3]

vtkDataArray * vtkFieldData::GetArray ( int i )

Not recommended for use.

Use GetAbstractArray(int i) instead.

Return the ith array in the field. A nullptr is returned if the index i is out of range, or if the array at the given index is not a vtkDataArray. To access vtkStringArray, vtkUnicodeStringArray, or vtkVariantArray, use GetAbstractArray(int i).

◆ GetArray() [2/3]

vtkDataArray * vtkFieldData::GetArray	(	const char *	arrayName,
		int &	index
	)

Not recommended for use.

Use GetAbstractArray(const char *arrayName, int &index) instead.

Return the array with the name given. Returns nullptr if array not found. A nullptr is also returned if the array with the given name is not a vtkDataArray. To access vtkStringArray, vtkUnicodeStringArray, or vtkVariantArray, use GetAbstractArray(const char* arrayName, int &index). Also returns the index of the array if found, -1 otherwise.

◆ GetArray() [3/3]

vtkDataArray * vtkFieldData::GetArray ( const char * arrayName )

inline

Not recommended for use.

Use GetAbstractArray(const char *arrayName) instead.

vtkAbstractArray * vtkFieldData::GetAbstractArray	(	const char *	arrayName,
		int &	index
	)

Return the array with the name given.

◆ GetAbstractArray() [3/3]

vtkAbstractArray * vtkFieldData::GetAbstractArray ( const char * arrayName )

inline

Return the array with the name given.

Returns nullptr if array not found. Unlike GetArray(), this method returns a vtkAbstractArray and can be used to access any array type.

Definition at line 290 of file vtkFieldData.h.

◆ HasArray()

int vtkFieldData::HasArray ( const char * name )

inline

Return 1 if an array with the given name could be found.

0 otherwise.

Definition at line 301 of file vtkFieldData.h.

◆ GetArrayName()

const char * vtkFieldData::GetArrayName ( int i )

inline

Get the name of ith array.

Note that this is equivalent to: GetAbstractArray(i)->GetName() if ith array pointer is not nullptr

Definition at line 316 of file vtkFieldData.h.

◆ PassData()

virtual void vtkFieldData::PassData ( vtkFieldData * fd )

virtual

Pass entire arrays of input data through to output.

Obey the "copy" flags.

Reimplemented in vtkDataSetAttributes.

◆ CopyFieldOn()

void vtkFieldData::CopyFieldOn ( const char * name )

inline

Turn on/off the copying of the field specified by name.

During the copying/passing, the following rules are followed for each array:

If the copy flag for an array is set (on or off), it is applied This overrides rule 2.
If CopyAllOn is set, copy the array. If CopyAllOff is set, do not copy the array

Definition at line 338 of file vtkFieldData.h.

inline

Definition at line 339 of file vtkFieldData.h.

◆ CopyAllOn()

virtual void vtkFieldData::CopyAllOn ( int unused = 0 )

virtual

Turn on copying of all data.

During the copying/passing, the following rules are followed for each array:

If CopyAllOn is set, copy the array. If CopyAllOff is set, do not copy the array

Reimplemented in vtkDataSetAttributes.

◆ CopyAllOff()

virtual void vtkFieldData::CopyAllOff ( int unused = 0 )

virtual

Turn off copying of all data.

During the copying/passing, the following rules are followed for each array:

If the copy flag for an array is set (on or off), it is applied This overrides rule 2.
If CopyAllOn is set, copy the array. If CopyAllOff is set, do not copy the array

Reimplemented in vtkDataSetAttributes.

◆ DeepCopy()

virtual void vtkFieldData::DeepCopy ( vtkFieldData * da )

virtual

Copy a field by creating new data arrays (i.e., duplicate storage).

Reimplemented in vtkDataSetAttributes.

◆ ShallowCopy()

virtual void vtkFieldData::ShallowCopy ( vtkFieldData * da )

virtual

Copy a field by reference counting the data arrays.

Reimplemented in vtkDataSetAttributes.

◆ Squeeze()

void vtkFieldData::Squeeze ( )

Squeezes each data array in the field (Squeeze() reclaims unused memory.)

◆ Reset()

void vtkFieldData::Reset ( )

Resets each data array in the field (Reset() does not release memory but it makes the arrays look like they are empty.)

◆ GetActualMemorySize()

virtual unsigned long vtkFieldData::GetActualMemorySize ( )

virtual

Return the memory in kibibytes (1024 bytes) consumed by this field data.

Used to support streaming and reading/writing data. The value returned is guaranteed to be greater than or equal to the memory required to actually represent the data represented by this object.

◆ GetMTime()

vtkMTimeType vtkFieldData::GetMTime ( )

overridevirtual

Check object's components for modified times.

Reimplemented from vtkObject.

◆ GetField()

void vtkFieldData::GetField	(	vtkIdList *	ptId,
		vtkFieldData *	f
	)

Get a field from a list of ids.

Supplied field f should have same types and number of data arrays as this one (i.e., like CopyStructure() creates). This method should not be used if the instance is from a subclass of vtkFieldData (vtkPointData or vtkCellData). This is because in those cases, the attribute data is stored with the other fields and will cause the method to behave in an unexpected way.

◆ GetArrayContainingComponent()

int vtkFieldData::GetArrayContainingComponent	(	int	i,
		int &	arrayComp
	)

Return the array containing the ith component of the field.

The return value is an integer number n 0<=n<this->NumberOfArrays. Also, an integer value is returned indicating the component in the array is returned. Method returns -1 if specified component is not in the field.

◆ GetNumberOfComponents()

int vtkFieldData::GetNumberOfComponents ( )

Get the number of components in the field.

This is determined by adding up the components in each non-nullptr array. This method should not be used if the instance is from a subclass of vtkFieldData (vtkPointData or vtkCellData). This is because in those cases, the attribute data is stored with the other fields and will cause the method to behave in an unexpected way.

◆ GetNumberOfTuples()

vtkIdType vtkFieldData::GetNumberOfTuples ( )

Get the number of tuples in the field.

Note: some fields have arrays with different numbers of tuples; this method returns the number of tuples in the first array. Mixed-length arrays may have to be treated specially. This method should not be used if the instance is from a subclass of vtkFieldData (vtkPointData or vtkCellData). This is because in those cases, the attribute data is stored with the other fields and will cause the method to behave in an unexpected way.

◆ SetNumberOfTuples()

void vtkFieldData::SetNumberOfTuples ( const vtkIdType number )

Set the number of tuples for each data array in the field.

This method should not be used if the instance is from a subclass of vtkFieldData (vtkPointData or vtkCellData). This is because in those cases, the attribute data is stored with the other fields and will cause the method to behave in an unexpected way.

◆ SetTuple()

void vtkFieldData::SetTuple	(	const vtkIdType	i,
		const vtkIdType	j,
		vtkFieldData *	source
	)

Set the jth tuple in source field data at the ith location.

Set operations mean that no range checking is performed, so they're faster.

◆ InsertTuple()

void vtkFieldData::InsertTuple	(	const vtkIdType	i,
		const vtkIdType	j,
		vtkFieldData *	source
	)

Insert the jth tuple in source field data at the ith location.

Range checking is performed and memory allocates as necessary.

◆ InsertNextTuple()

vtkIdType vtkFieldData::InsertNextTuple	(	const vtkIdType	j,
		vtkFieldData *	source
	)

Insert the jth tuple in source field data at the end of the tuple matrix.

Range checking is performed and memory is allocated as necessary.

void vtkFieldData::SetArray	(	int	i,
		vtkAbstractArray *	array
	)

protected

Set an array to define the field.
