Class IndirectCallNode

java.lang.Object

com.oracle.truffle.api.nodes.Node

com.oracle.truffle.api.nodes.IndirectCallNode

All Implemented Interfaces:

NodeInterface, Cloneable

public abstract class IndirectCallNode
extends Node

Represents an indirect call to a CallTarget. Indirect calls are calls for which the CallTarget may change dynamically for each consecutive call. This part of the Truffle API enables the runtime system to perform additional optimizations on indirect calls.

Please note: This class is not intended to be sub classed by guest language implementations.

See DirectCallNode for faster calls with a constantly known CallTarget.

Since:

0.8 or earlier

Method Details

call

public abstract Object call(CallTarget target,
 Object... arguments)

Performs an indirect call to the given CallTarget target with the provided arguments.

Parameters:

target - the CallTarget to call

arguments - the arguments to provide

Returns:

the return value of the call

Since:

0.23

create

public static IndirectCallNode create()

Creates cached indirect call node using bytecode index -1.

Since:

0.8 or earlier

getUncached

public static IndirectCallNode getUncached()

Returns an uncached version of an indirect call node. Uncached versions of an indirect call node use the current encapsulating node as source location.
