Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

void vtkBlockSelector::PrintSelf	(	ostream &	os,

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.

void vtkBlockSelector::Initialize	(	vtkSelectionNode *	node,
		const std::string &	insidednessArrayName
	)

overridevirtual

Sets the vtkSelectionNode used by this selection operator and initializes the data structures in the selection operator based on the selection.

(for example in the vtkFrustumSelector this creates the vtkPlanes implicit function to represent the frustum).

Parameters

node	The selection node that determines the behavior of this operator.
insidednessArrayName	The name of the insidedness array to add to the output from this operator.

Reimplemented from vtkSelector.

bool vtkBlockSelector::ComputeSelectedElementsForBlock	(	vtkDataObject *	input,
		vtkSignedCharArray *	insidednessArray,
		unsigned int	compositeIndex,
		unsigned int	amrLevel,
		unsigned int	amrIndex
	)

overrideprotectedvirtual

This method computes whether or not each element in the dataset is inside the selection and populates the given array with 0 (outside the selection) or 1 (inside the selection).

The vtkDataObject passed in should be a non-composite data object.

What type of elements are operated over is determined by the vtkSelectionNode's field association. The insidednessArray passed in should have the correct number of elements for that field type or it will be resized. The last three parameters give the data object's composite index, AMR level or AMR index.

Returns true for successful completion. The operator should only return false when it cannot operate on the inputs.

Implements vtkSelector.
