Method Summary

Modifier and Type	Method	Description
static List<SubGraph>	getSubgraphsMatching(SameDiff sd, SubGraphPredicate p)	Get a list of all the subgraphs that match the specified predicate
static SameDiff	replaceSubgraphsMatching(@NonNull SameDiff sd, @NonNull SubGraphPredicate p, @NonNull SubGraphProcessor processor)	Find all of the subgraphs that match the specified SubGraphPredicate and then replace them with a different subgraph. Note that the original SameDiff instance is not modified; a copy is made, which is then modified and returned.

Method Detail

replaceSubgraphsMatching

public static SameDiff replaceSubgraphsMatching(@NonNull
                                                @NonNull SameDiff sd,
                                                @NonNull
                                                @NonNull SubGraphPredicate p,
                                                @NonNull
                                                @NonNull SubGraphProcessor processor)

Find all of the subgraphs that match the specified SubGraphPredicate and then replace them with a different subgraph.
Note that the original SameDiff instance is not modified; a copy is made, which is then modified and returned.
Note: For each subgraph to be replaced by SubGraphProcessor, its replacement should have the same number of output SDVariables.

Parameters:

sd - SameDiff instance to copy and modify

p - SubGraphPredicate to define and select the subgraphs that should be modified or replaced

processor - SubGraphProcessor is used to define how the subgraphs (selected by the SubGraphPredicate) should be modified/replaced

Returns:

A SameDiff instance that has been modified

getSubgraphsMatching

public static List<SubGraph> getSubgraphsMatching(SameDiff sd,
                                                  SubGraphPredicate p)

Get a list of all the subgraphs that match the specified predicate

Parameters:

sd - SameDiff instance to get the subgraphs for

p - Subgraph predicate. This defines the subgraphs that should be selected in the SameDiff instance

Returns:

Subgraphs
