Method Details

getClassName

public final com.oracle.truffle.api.strings.TruffleString getClassName()

Description copied from class: JSDynamicObject

The [[Class]] internal property. For ES5, this is the second part of what Object.prototype.toString.call(myObj) returns, e.g. "[object Array]".

Overrides:

getClassName in class JSNonProxyObject

getBuiltinToStringTag

public final com.oracle.truffle.api.strings.TruffleString getBuiltinToStringTag()

Description copied from class: JSObject

Returns builtinTag as per Object.prototype.toString(). By default returns "Object".

Overrides:

getBuiltinToStringTag in class JSObject

Returns:

built-in toStringTag

getMembers

public final Object getMembers(boolean includeInternal,
 com.oracle.truffle.api.interop.InteropLibrary self)

hasArrayElements

public final boolean hasArrayElements()

getArraySize

public final long getArraySize()

readArrayElement

public final 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.UnsupportedMessageException

isArrayElementReadable

public final boolean isArrayElementReadable(long index,
 com.oracle.truffle.api.interop.InteropLibrary thisLibrary)

writeArrayElement

public final void writeArrayElement(long index,
 Object value,
 ArrayElementInfoNode elements,
 ImportValueNode castValueNode,
 WriteElementNode writeNode)
                             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.UnsupportedMessageException

isArrayElementModifiable

public final boolean isArrayElementModifiable(long index,
 ArrayElementInfoNode elements)

isArrayElementInsertable

public final boolean isArrayElementInsertable(long index,
 ArrayElementInfoNode elements)
