Member Function Documentation

static vtkExodusIIReaderPrivate* vtkExodusIIReaderPrivate::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

void vtkExodusIIReaderPrivate::PrintData	(	ostream &	os,
		vtkIndent	indent
	)

virtual const char* vtkExodusIIReaderPrivate::GetClassName ( ) [virtual]

Reimplemented from vtkObject.

static int vtkExodusIIReaderPrivate::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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.

Reimplemented from vtkObject.

virtual int vtkExodusIIReaderPrivate::IsA ( const char * name ) [virtual]

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.

Reimplemented from vtkObject.

static vtkExodusIIReaderPrivate* vtkExodusIIReaderPrivate::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkObject.

int vtkExodusIIReaderPrivate::OpenFile ( const char * filename )

Open an ExodusII file for reading. Returns 0 on success.

int vtkExodusIIReaderPrivate::CloseFile ( )

Close any ExodusII file currently open for reading. Returns 0 on success.

int vtkExodusIIReaderPrivate::RequestInformation ( )

Get metadata for an open file with handle exoid.

vtkMutableDirectedGraph* vtkExodusIIReaderPrivate::GetSIL ( ) [inline]

Returns the SIL. This valid only after BuildSIL() has been called.

Definition at line 46 of file vtkExodusIIReaderPrivate.h.

void vtkExodusIIReaderPrivate::Broadcast ( vtkMultiProcessController * controller )

Send metadata to other processes in a parallel job.

void vtkExodusIIReaderPrivate::Receive ( vtkMultiProcessController * controller )

Receive metadata from the rank 0 process in a parallel job.

int vtkExodusIIReaderPrivate::RequestData	(	vtkIdType	timeStep,
		vtkMultiBlockDataSet *	output
	)

Read requested data and store in unstructured grid.

int vtkExodusIIReaderPrivate::SetUpEmptyGrid ( vtkMultiBlockDataSet * output )

void vtkExodusIIReaderPrivate::Reset ( )

Reset the class so that another file may be read.

This does not change any user-specified parameters, such as which generated arrays should be present, whether there are mode shapes or time steps, etc. Note that which arrays should be loaded is a more delicate issue; if you set these after RequestInformation has been called, these will not be saved. Any settings you make before RequestInformation is called will be saved because they are stored in InitialArrayInfo and InitialObjectInfo.

void vtkExodusIIReaderPrivate::ResetSettings ( )

Return user-specified variables to their default values.

Calling ResetSettings() and then Reset() will return the class to a state just like it was after New() was called.

void vtkExodusIIReaderPrivate::ResetCache ( )

Clears out any data in the cache and restores it to its initial state.

int vtkExodusIIReaderPrivate::GetNumberOfTimeSteps ( ) [inline]

Return the number of time steps in the open file.

You must have called RequestInformation() before invoking this member function.

Definition at line 89 of file vtkExodusIIReaderPrivate.h.

virtual int vtkExodusIIReaderPrivate::GetTimeStep ( ) [virtual]

Return the current time step.

virtual void vtkExodusIIReaderPrivate::SetTimeStep ( int ) [virtual]

Set the current time step for subsequent calls to RequestData().

virtual int vtkExodusIIReaderPrivate::GetSqueezePoints ( ) [virtual]

Return whether subsequent RequestData() calls will produce the minimal point set required to represent the output.

void vtkExodusIIReaderPrivate::SetSqueezePoints ( int sp )

Set whether subsequent RequestData() calls will produce the minimal point set required to represent the output.

virtual void vtkExodusIIReaderPrivate::SqueezePointsOn ( ) [virtual]

Convenience routines that for producing (or not) the minimal point set required to represent the output.

virtual void vtkExodusIIReaderPrivate::SqueezePointsOff ( ) [virtual]

int vtkExodusIIReaderPrivate::GetNumberOfNodes ( )

Return the number of nodes in the output (depends on SqueezePoints).

int vtkExodusIIReaderPrivate::GetNumberOfObjectsOfType ( int otype )

Returns the number of objects of a given type (e.g., EX_ELEM_BLOCK, EX_NODE_SET, .

..). You must have called RequestInformation before invoking this member function.

int vtkExodusIIReaderPrivate::GetNumberOfObjectArraysOfType ( int otype )

Returns the number of arrays defined over objects of a given type (e.g., EX_ELEM_BLOCK, EX_NODE_SET, .

..). You must have called RequestInformation before invoking this member function.

N.B.: This method will eventually disappear. Really, what we should be providing is an interface to query the arrays defined on a particular object, not a class of objects. However, until the reader outputs multiblock datasets, we can't be that specific.

const char* vtkExodusIIReaderPrivate::GetObjectName	(	int	otype,
		int	i
	)

For a given object type, returns the name of the i-th object.
