Detailed Description

vtkPDirectory provides a portable way of finding the names of the files in a system directory where process 0 finds the information and broadcasts it to other processes.

It tries to replicate the API for both Directory and vtkDirectory though there are slight mismatches between the two. This is a blocking collective operation.

Return 1 if this class is the same type of (or a subclass of) the named class.

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

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.

bool vtkPDirectory::Load ( const std::string & )

Open/Load the specified directory and load the names of the files in that directory.

false/0 is returned if the directory can not be opened, true/1 if it is opened. The reason that there are two versions of this is that Directory uses Load() and vtkDirectory uses Open() for this functionality.

int vtkPDirectory::Open ( const char * dir )

Open/Load the specified directory and load the names of the files in that directory.

false/0 is returned if the directory can not be opened, true/1 if it is opened. The reason that there are two versions of this is that Directory uses Load() and vtkDirectory uses Open() for this functionality.

vtkIdType vtkPDirectory::GetNumberOfFiles ( ) const

Return the number of files in the current directory.

const char* vtkPDirectory::GetFile ( vtkIdType index ) const

Return the file at the given index, the indexing is 0 based.

int vtkPDirectory::FileIsDirectory ( const char * name )

Return true if the file is a directory.

If the file is not an absolute path, it is assumed to be relative to the opened directory. If no directory has been opened, it is assumed to be relative to the current working directory.

virtual vtkStringArray* vtkPDirectory::GetFiles ( )

virtual

Get an array that contains all the file names.

const char* vtkPDirectory::GetPath ( ) const

Return the path to Open'ed directory.

void vtkPDirectory::Clear ( )

Clear the internal structure.

Used internally at beginning of Load(...) to clear the cache.
