Class Node.Builder

java.lang.Object

org.eclipse.gef.graph.Node.Builder

Enclosing class:

Node

public static class Node.Builder
extends Object

The Node.Builder can be used to construct a Node little by little.

Constructor Summary

Constructors

Constructor	Description
Builder()	Constructs a new (anonymous) context-free Node.Builder, which can only be used to construct a single node via buildNode(), i.e. which cannot be chained.
Builder(Graph.Builder.Context context)	Constructs a new (anonymous) Node.Builder for the given Graph.Builder.Context.
Builder(Graph.Builder.Context context, Object key)	Constructs a new identifiable Node.Builder for the given Graph.Builder.Context.

Method Summary

Modifier and Type	Method	Description
Node.Builder	attr(String key, Object value)	Puts the given key-value-pair into the attributesProperty map of the Node which is constructed by this Node.Builder.
<T> Node.Builder	attr(BiConsumer<Node,T> setter, T value)	Uses the given setter to set the attribute value.
Graph	build()	Constructs a new Graph from the values which have been supplied to the builder chain.
Node	buildNode()	Creates a new Node, setting the values specified via this Node.Builder.
Edge.Builder	edge(Object sourceNodeOrKey, Object targetNodeOrKey)	Constructs a new Edge.Builder.
protected Object	getKey()	Returns the key that can be used to identify this Node.Builder
Node.Builder	node()	Constructs a new (anonymous) Node.Builder.
Node.Builder	node(Object key)	Constructs a new (identifiable) Node.Builder.

Constructor Details

Builder

public Builder()

Constructs a new (anonymous) context-free Node.Builder, which can only be used to construct a single node via buildNode(), i.e. which cannot be chained.

Builder

public Builder(Graph.Builder.Context context)

Constructs a new (anonymous) Node.Builder for the given Graph.Builder.Context.

Parameters:

context - The context in which the Node.Builder is used.

Builder

public Builder(Graph.Builder.Context context,
 Object key)

Constructs a new identifiable Node.Builder for the given Graph.Builder.Context.

Parameters:

context - The context in which the Node.Builder is used.

key - The key to identify the builder.

Method Details

attr

public <T> Node.Builder attr(BiConsumer<Node,T> setter,
 T value)

Uses the given setter to set the attribute value.

Type Parameters:

T - The type of the attribute.

Parameters:

setter - The setter to apply.

value - The value to apply.

Returns:

this for convenience.

attr

public Node.Builder attr(String key,
 Object value)

Puts the given key-value-pair into the attributesProperty map of the Node which is constructed by this Node.Builder.

Parameters:

key - The attribute name which is inserted.

value - The attribute value which is inserted.

Returns:

this for convenience.

build

public Graph build()

Constructs a new Graph from the values which have been supplied to the builder chain.

Returns:

A new Graph.

buildNode

public Node buildNode()

Creates a new Node, setting the values specified via this Node.Builder.

Returns:

A newly created Node.

edge

public Edge.Builder edge(Object sourceNodeOrKey,
 Object targetNodeOrKey)

Constructs a new Edge.Builder.

Parameters:

sourceNodeOrKey - The source Node or a key to identify the source Node (or its Node.Builder).

targetNodeOrKey - The target Node or a key to identify the target Node (or its Node.Builder).

Returns:

A new Edge.Builder.

getKey

protected Object getKey()

Returns the key that can be used to identify this Node.Builder

Returns:

The key that can be used for identification.

node

public Node.Builder node()

Constructs a new (anonymous) Node.Builder.

Returns:

A new Node.Builder.

node

public Node.Builder node(Object key)

Constructs a new (identifiable) Node.Builder.

Parameters:

key - The key that can be used to identify the Node.Builder

Returns:

A new Node.Builder.
