                     throws com.oracle.truffle.api.interop.ArityException,
com.oracle.truffle.api.interop.UnsupportedTypeException,
com.oracle.truffle.api.interop.UnsupportedMessageException

Interpret a pointer as function pointer with the given signature and call it.

Throws:

com.oracle.truffle.api.interop.ArityException

com.oracle.truffle.api.interop.UnsupportedTypeException

com.oracle.truffle.api.interop.UnsupportedMessageException

bind

public abstract Object bind(Object signature,
 Object functionPointer)

Create an executable interop object from a signature and a function pointer. Sending the InteropLibrary.execute(java.lang.Object, java.lang.Object...) message to the returned object is equivalent to calling call(java.lang.Object, java.lang.Object, java.lang.Object...).

createClosure

public abstract Object createClosure(Object signature,
 Object executable)

Create a native closure object with the given signature. The returned object is a function pointer that sends the InteropLibrary.execute(java.lang.Object, java.lang.Object...) message to the executable object when called.

getFactory

public static com.oracle.truffle.api.library.LibraryFactory<SignatureLibrary> getFactory()

getUncached

public static SignatureLibrary getUncached()
