Detailed Description

abstract superclass for all circle packing layout strategies.

All subclasses of this class perform a circle packing layout on a vtkTree. This involves assigning a circle to each vertex in the tree, and placing that information in a data array with three components per tuple representing (Xcenter, Ycenter, Radius).

Instances of subclasses of this class may be assigned as the layout strategy to vtkCirclePackLayout

Member Function Documentation

virtual const char* vtkCirclePackLayoutStrategy::GetClassName

(

)

[virtual]

Reimplemented from vtkObject.

Reimplemented in vtkCirclePackFrontChainLayoutStrategy.

static int vtkCirclePackLayoutStrategy::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.

Reimplemented in vtkCirclePackFrontChainLayoutStrategy.

virtual int vtkCirclePackLayoutStrategy::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.

Reimplemented in vtkCirclePackFrontChainLayoutStrategy.

[static]

Reimplemented from vtkObject.

Reimplemented in vtkCirclePackFrontChainLayoutStrategy.

void vtkCirclePackLayoutStrategy::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		[virtual]

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 vtkCirclePackFrontChainLayoutStrategy.

virtual void vtkCirclePackLayoutStrategy::Layout	(	vtkTree *	inputTree,
		vtkDataArray *	areaArray,
		vtkDataArray *	sizeArray
	)		[pure virtual]

Perform the layout of the input tree, and store the circle bounds of each vertex as a tuple in a data array. (Xcenter, Ycenter, Radius). The sizeArray may be NULL, or may contain the desired size of each vertex in the tree.

Implemented in vtkCirclePackFrontChainLayoutStrategy.
