execute

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

Description copied from class: 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.

Overrides:

execute in class 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 unless it is a decorator.

getConstantArguments

protected Object[] getConstantArguments(ResolvedJavaMethod targetMethod)

Provide any extra arguments that should be passed to the Snippet as Snippet.ConstantParameter arguments.
