getArraySize

public long getArraySize()

readArrayElement

public Object readArrayElement(long index,
 com.oracle.truffle.api.interop.InteropLibrary self,
 ReadElementNode readNode,
 ExportValueNode exportNode)
                        throws com.oracle.truffle.api.interop.InvalidArrayIndexException,
com.oracle.truffle.api.interop.UnsupportedMessageException

Throws:

com.oracle.truffle.api.interop.InvalidArrayIndexException

 com.oracle.truffle.api.interop.InteropLibrary thisLibrary)

writeArrayElement

public void writeArrayElement(long index,
 Object value,
 ImportValueNode castValueNode,
 WriteElementNode writeNode,
 com.oracle.truffle.api.interop.InteropLibrary thisLibrary)
                       throws com.oracle.truffle.api.interop.InvalidArrayIndexException,

Throws:

com.oracle.truffle.api.interop.InvalidArrayIndexException

com.oracle.truffle.api.interop.UnsupportedMessageException

isArrayElementInsertable

public boolean isArrayElementInsertable(long index)

testIntegrityLevel

public boolean testIntegrityLevel(boolean frozen)

Description copied from class: JSDynamicObject

TestIntegrityLevel(O, level).

Overrides:

testIntegrityLevel in class JSNonProxyObject

setIntegrityLevel

public boolean setIntegrityLevel(boolean freeze,
 boolean doThrow)

Description copied from class: JSDynamicObject

SetIntegrityLevel(O, level).

Overrides:

setIntegrityLevel in class JSNonProxyObject

toDisplayStringImpl

public com.oracle.truffle.api.strings.TruffleString toDisplayStringImpl(boolean allowSideEffects,
 ToDisplayStringFormat format,
 int depth)

Description copied from class: JSDynamicObject

A more informative toString variant, mainly used for error messages.

Overrides:

toDisplayStringImpl in class JSNonProxyObject

Parameters:

format - formatting parameters

depth - current nesting depth
