Example 79 with InteropLibrary

use of com.oracle.truffle.api.interop.InteropLibrary in project graal by oracle.

the class VM method processCallBackResult.

/**
 * Registers this known VM method's function pointer. Later native method bindings can perform a
 * lookup when trying to bind to a function pointer, and if a match happens, this is a known VM
 * method, and we can link directly to it thus bypassing native calls.
 *
 * @param name The name of the VM method, previously extracted from {@code args[0]}.
 * @param factory The node factory of the requested VM method.
 * @param args A length {@linkplain #lookupCallBackArgsCount() 2} arguments array: At position 0
 *            is a native pointer to the name of the method. At position 1 is the address of the
 *            {@code JVM_*} symbol exported by {@code mokapot}.
