Class NativeArrayBufferView
java.lang.Object
org.mozilla.javascript.ScriptableObject
org.mozilla.javascript.IdScriptableObject
org.mozilla.javascript.typedarrays.NativeArrayBufferView
- All Implemented Interfaces:
Serializable
,ConstProperties
,DebuggableObject
,IdFunctionCall
,Scriptable
,SymbolScriptable
- Direct Known Subclasses:
NativeDataView
,NativeTypedArrayView
This class is the abstract parent for all views of the array. It shows a view of the underlying
NativeArrayBuffer. Many views may simultaneously share the same buffer, and changes to one will
affect all.

getMaxInstanceId
protected int getMaxInstanceId()Description copied from class:IdScriptableObject
Get maximum id findInstanceIdInfo can generate.- Overrides:
getMaxInstanceId

getInstanceIdName
Description copied from class:IdScriptableObject
Map id back to property name it defines.- Overrides:
getInstanceIdName
in classIdScriptableObject
