execute

public boolean execute(GraphBuilderContext b,
                       ResolvedJavaMethod targetMethod,
                       InvocationPlugin.Receiver receiver,
                       ValueNode[] args)

Description copied from interface: InvocationPlugin

Executes this plugin against a set of invocation arguments. The default implementation in InvocationPlugin dispatches to the apply(...) method that matches the number of arguments or to InvocationPlugin.applyPolymorphic(com.oracle.graal.graphbuilderconf.GraphBuilderContext, jdk.internal.jvmci.meta.ResolvedJavaMethod, com.oracle.graal.graphbuilderconf.InvocationPlugin.Receiver, com.oracle.graal.nodes.ValueNode...) if plugin is signature polymorphic.

Specified by:

execute in interface InvocationPlugin

targetMethod - the method for which this plugin is being applied

receiver - access to the receiver, null if targetMethod is static

args - all arguments to the invocation include the receiver in position 0 if targetMethod is not static

Returns:

true if this plugin handled the invocation of targetMethod false if the graph builder should process the invoke further (e.g., by inlining it or creating an Invoke node). A plugin that does not handle an invocation must not modify the graph being constructed.
