Layout Buffers ( LayoutBuffer )

Baseclasses

Definition

A layout buffer for graph G is a layout interface that stores the following graphical attributes for graph G:

• the position of each node.
• the bend points of each edge.
• the source and target anchor of each edge.

The class LayoutBuffer overrides the pure virtual methods of LayoutInterface for setting and getting these attributes. The methods set_width(), get_width(), set_height(), and get_height() must be overridden by derived classes. Layout buffers are mainly used as base class for GraphCopyLI and AGDLayout.

Initialization

LayoutBuffer	A(const leda_graph& G)	initializes a layout buffer for graph G.
LayoutBuffer	A(const LayoutBuffer& lb)	copy constructor.

Operations

LayoutBuffer inherits the operations from its base class LayoutInterface (see Sect. Layout Interfaces)
