public class GraphPort

Object
GraphPort

A place on a GraphNode where edges attach, as in a node editor.

A node with no ports is connected node to node, as in a system diagram. Ports are ordered on their side of the node in the order they were added.

Fields

`public static final int INPUT = 0`	The port takes incoming edges and sits on the leading side of the node.
`public static final int OUTPUT = 1`	The port starts outgoing edges and sits on the trailing side.

Constructors

public GraphPort(String id, int direction, String label, String type) A port.

Methods

`public` `String getId()`	The id, unique within the node.
`public int getDirection()`	`INPUT` or `OUTPUT`.
`public boolean isInput()`	True for an `INPUT` port.
`public` `String getLabel()`	The label, or null.
`public void setLabel(String label)`	Sets the label.
`public` `String getType()`	The data type edges must agree on, or null for any.
`public void setType(String type)`	Sets the data type.
`public int getMaxConnections()`	How many edges may attach, or -1 for any number.
`public void setMaxConnections(int maxConnections)`	Limits the edges that may attach; -1 for any number.
`public` `GraphNode getNode()`	The node the port belongs to, or null before it is added to one.
