heros.edgefunc

Class EdgeIdentity<V>

java.lang.Object

heros.edgefunc.EdgeIdentity<V>

Type Parameters:

V - The type of values to be computed along flow edges.

All Implemented Interfaces:

EdgeFunction<V>

public class EdgeIdentity<V>
extends java.lang.Object
implements EdgeFunction<V>

The identity function on graph edges

Method Summary

Modifier and Type	Method and Description
EdgeFunction<V>	composeWith(EdgeFunction<V> secondFunction) Composes this function with the secondFunction, effectively returning a summary function that maps sources to targets exactly as if first this function had been applied and then the secondFunction.
V	computeTarget(V source) Computes the value resulting from applying this function to source.
boolean	equalTo(EdgeFunction<V> other) Returns true is this function represents exactly the same source to target mapping as other.
EdgeFunction<V>	joinWith(EdgeFunction<V> otherFunction) Returns a function that represents that (element-wise) join of this function with otherFunction.
java.lang.String	toString()
static <A> EdgeIdentity<A>	v()

Method Detail

computeTarget

public V computeTarget(V source)

Description copied from interface: EdgeFunction

Computes the value resulting from applying this function to source.

Specified by:

computeTarget in interface EdgeFunction<V>

composeWith

public EdgeFunction<V> composeWith(EdgeFunction<V> secondFunction)

Description copied from interface: EdgeFunction

Composes this function with the secondFunction, effectively returning a summary function that maps sources to targets exactly as if first this function had been applied and then the secondFunction.

Specified by:

composeWith in interface EdgeFunction<V>

joinWith

public EdgeFunction<V> joinWith(EdgeFunction<V> otherFunction)

Description copied from interface: EdgeFunction

Returns a function that represents that (element-wise) join of this function with otherFunction. Naturally, this is a symmetric operation.

Specified by:

joinWith in interface EdgeFunction<V>

equalTo

public boolean equalTo(EdgeFunction<V> other)

Description copied from interface: EdgeFunction

Returns true is this function represents exactly the same source to target mapping as other.

Specified by:

equalTo in interface EdgeFunction<V>

v
