| IdScriptableObject | | abstract public class IdScriptableObject extends ScriptableObject implements IdFunctionCall(Code) | | Base class for native object implementation that uses IdFunctionObject to export its methods to script via .prototype object.
Any descendant should implement at least the following methods:
findInstanceIdInfo
getInstanceIdName
execIdCall
methodArity
To define non-function properties, the descendant should override
getInstanceIdValue
setInstanceIdValue
to get/set property value and provide its default attributes.
To customize initializition of constructor and protype objects, descendant
may override scopeInit or fillConstructorProperties methods.

| Method Summary | |
| final public void | activatePrototypeMap(int maxPrototypeId)
| | protected void | addIdFunctionProperty(Scriptable obj, Object tag, int id, String name, int arity)
| | final protected Object | defaultGet(String name)
| | final protected void | defaultPut(String name, Object value)
| | public void | delete(String name)
| | public Object | execIdCall(IdFunctionObject f, Context cx, Scriptable scope, Scriptable thisObj, Object[] args)
'thisObj' will be null if invoked as constructor, in which case
instance of Scriptable should be returned. | | final public IdFunctionObject | exportAsJSClass(int maxPrototypeId, Scriptable scope, boolean sealed)
| | protected void | fillConstructorProperties(IdFunctionObject ctor)
| | protected int | findInstanceIdInfo(String name)
Map name to id of instance property. | | protected int | findPrototypeId(String name)
| | public Object | get(String name, Scriptable start)
| | public int | getAttributes(String name)
| | Object[] | getIds(boolean getAll)
| | protected String | getInstanceIdName(int id)
Map id back to property name it defines. | | protected Object | getInstanceIdValue(int id)
Get id value. | | protected int | getMaxInstanceId()
Get maximum id findInstanceIdInfo can generate. | | public boolean | has(String name, Scriptable start)
| | final public boolean | hasPrototypeMap()
| | protected static EcmaError | incompatibleCallError(IdFunctionObject f)
Utility method to construct type error to indicate incompatible call
when converting script thisObj to a particular type is not possible.
Possible usage would be to have a private function like realThis:
private static NativeSomething realThis(Scriptable thisObj,
IdFunctionObject f)
{
if (!(thisObj instanceof NativeSomething))
throw incompatibleCallError(f);
return (NativeSomething)thisObj;
}
Note that although such function can be implemented universally via
java.lang.Class.isInstance(), it would be much more slower.
Parameters:
f - function that is attempting to convert 'this'object. | | final public void | initPrototypeConstructor(IdFunctionObject f)
| | protected void | initPrototypeId(int id)
| | final public void | initPrototypeMethod(Object tag, int id, String name, int arity)
| | final public void | initPrototypeValue(int id, String name, Object value, int attributes)
| | protected static int | instanceIdInfo(int attributes, int id)
| | public void | put(String name, Scriptable start, Object value)
| | public void | setAttributes(String name, int attributes)
| | protected void | setInstanceIdValue(int id, Object value)
Set or delete id value. |
| IdScriptableObject | | public IdScriptableObject()(Code) | | |
| activatePrototypeMap | | final public void activatePrototypeMap(int maxPrototypeId)(Code) | | |
| findPrototypeId | | protected int findPrototypeId(String name)(Code) | | |
| getInstanceIdName | | protected String getInstanceIdName(int id)(Code) | | Map id back to property name it defines.
|
| getInstanceIdValue | | protected Object getInstanceIdValue(int id)(Code) | | Get id value.
If id value is constant, descendant can call cacheIdValue to store
value in the permanent cache.
Default implementation creates IdFunctionObject instance for given id
and cache its value
|
| getMaxInstanceId | | protected int getMaxInstanceId()(Code) | | Get maximum id findInstanceIdInfo can generate.
|
| hasPrototypeMap | | final public boolean hasPrototypeMap()(Code) | | |
| incompatibleCallError | | protected static EcmaError incompatibleCallError(IdFunctionObject f)(Code) | | Utility method to construct type error to indicate incompatible call
when converting script thisObj to a particular type is not possible.
Possible usage would be to have a private function like realThis:
private static NativeSomething realThis(Scriptable thisObj,
IdFunctionObject f)
{
if (!(thisObj instanceof NativeSomething))
throw incompatibleCallError(f);
return (NativeSomething)thisObj;
}
Note that although such function can be implemented universally via
java.lang.Class.isInstance(), it would be much more slower.
Parameters:
f - function that is attempting to convert 'this'object. Scriptable object suitable for a check by the instanceofoperator.
throws:
RuntimeException - if no more instanceof target can be found |
| initPrototypeId | | protected void initPrototypeId(int id)(Code) | | |
| initPrototypeMethod | | final public void initPrototypeMethod(Object tag, int id, String name, int arity)(Code) | | |
| initPrototypeValue | | final public void initPrototypeValue(int id, String name, Object value, int attributes)(Code) | | |
| instanceIdInfo | | protected static int instanceIdInfo(int attributes, int id)(Code) | | |
| setAttributes | | public void setAttributes(String name, int attributes)(Code) | | |
| setInstanceIdValue | | protected void setInstanceIdValue(int id, Object value)(Code) | | Set or delete id value. If value == NOT_FOUND , the implementation
should make sure that the following getInstanceIdValue return NOT_FOUND.
