Enum Constant Summary

Enum Constants

Enum Constant	Description
AFTER_DECODING_FIELDS	Graph decoding (partial evaluation) may create nodes adding them to the graph in a "stub" form before filling any node fields.
BEFORE_DECODING_FIELDS	Graph decoding (partial evaluation) may create nodes adding them to the graph in a "stub" form before filling any node fields.
INPUT_CHANGED	A node's input is changed.
NODE_ADDED	A node was added to a graph.
NODE_REMOVED	A node was removed from the graph.
ZERO_USAGES	A node's usages count dropped to zero.

Method Summary

Modifier and Type	Method	Description
static Graph.NodeEvent	valueOf(String name)	Returns the enum constant of this class with the specified name.
static Graph.NodeEvent[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

INPUT_CHANGED

public static final Graph.NodeEvent INPUT_CHANGED

A node's input is changed.

ZERO_USAGES

public static final Graph.NodeEvent ZERO_USAGES

A node's usages count dropped to zero.

NODE_ADDED

public static final Graph.NodeEvent NODE_ADDED

A node was added to a graph.

NODE_REMOVED

public static final Graph.NodeEvent NODE_REMOVED

A node was removed from the graph.

BEFORE_DECODING_FIELDS

public static final Graph.NodeEvent BEFORE_DECODING_FIELDS

Graph decoding (partial evaluation) may create nodes adding them to the graph in a "stub" form before filling any node fields. We want to observe these events as well. This event is triggered before a "stub" node's fields are decoded and initialized.

AFTER_DECODING_FIELDS

public static final Graph.NodeEvent AFTER_DECODING_FIELDS

Graph decoding (partial evaluation) may create nodes adding them to the graph in a "stub" form before filling any node fields. We want to observe these events as well. This event is triggered after a "stub" node's fields are decoded and populated i.e. when the node is no longer a stub.

Method Details

values

public static Graph.NodeEvent[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Graph.NodeEvent valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
