Provides the fundamental classes and interfaces that model an efficient graph data type (class com.yworks.yfiles.base.Graph), its nodes and edges (classes com.yworks.yfiles.base.Node and com.yworks.yfiles.base.Edge), and related container structures and iteration mechanisms (class com.yworks.yfiles.base.YList and interface com.yworks.yfiles.base.YCursor).

Furthermore, this package also defines the infrastructure for association of additional data with graph elements, namely "data accessors," i.e., interfaces com.yworks.yfiles.base.DataAcceptor, com.yworks.yfiles.base.DataProvider, and com.yworks.yfiles.base.DataMap .

The section on Binding Data to Graph Elements explains the concept of data accessors.

	Interface	Description
	DataAcceptor	A general interface for setting data.

	Class	Description
	Edge	Represents an edge, i.e., a directed connection between two nodes (represented by instances of class com.yworks.yfiles.base.Node) in the directed graph data type com.yworks.yfiles.base.Graph.
	EdgeList	Specialized list implementation for instances of type com.yworks.yfiles.base.Edge.
	Graph	This class implements a directed graph structure.
	GraphCopyFactory	Very simple default implementation of a Copy Factory that creates com.yworks.yfiles.base.Graph instances and simply delegates to the com.yworks.yfiles.base.Graph.createNode() and com.yworks.yfiles.base.Graph.createEdge() method.
	GraphEvent	An event which indicates that a graph structure change occurred.
	InvalidGraphStructureException	Exception thrown when a graph-structural precondition is violated.
	ListCell	Represents a so-called "cell" or "link" of the doubly linked list implementation com.yworks.yfiles.base.YList.
	Node	Represents a so-called node in the directed graph data type com.yworks.yfiles.base.Graph.
	NodeList	Specialized list implementation for instances of type com.yworks.yfiles.base.Node.
	YList	An implementation of a doubly linked list that provides direct access to the cells that store the elements.
	YList_ListCursorImpl	Cursor implementation for class YList.
