Method Detail
-
get
public java.lang.Object get(int index, Scriptable start)
Description copied from class:ScriptableObject
Returns the value of the indexed property or NOT_FOUND.- Specified by:
get
in interfaceScriptable
- Overrides:
get
in classScriptableObject
- Parameters:
index
- the numeric index for the propertystart
- the object in which the lookup began- Returns:
- the value of the property (may be null), or NOT_FOUND
- See Also:
Scriptable.get(String,Scriptable)
-
has
public boolean has(int index, Scriptable start)
Description copied from class:ScriptableObject
Returns true if the property index is defined.- Specified by:
has
in interfaceScriptable
- Overrides:
has
in classScriptableObject
- Parameters:
index
- the numeric index for the propertystart
- the object in which the lookup began- Returns:
- true if and only if the property was found in the object
- See Also:
Scriptable.get(int, Scriptable)
,ScriptableObject.getProperty(Scriptable, int)
-
put
public void put(int index, Scriptable start, java.lang.Object val)
Description copied from class:ScriptableObject
Sets the value of the indexed property, creating it if need be.- Specified by:
put
in interfaceScriptable
- Overrides:
put
in classScriptableObject
- Parameters:
index
- the numeric index for the propertystart
- the object whose property is being setval
- value to set the property to- See Also:
Scriptable.has(int, Scriptable)
,Scriptable.get(int, Scriptable)
,ScriptableObject.putProperty(Scriptable, int, Object)
,Context.toObject(Object, Scriptable)
-
delete
public void delete(int index)
Description copied from class:ScriptableObject
Removes the indexed property from the object. If the property is not found, or it has the PERMANENT attribute, no action is taken.- Specified by:
delete
in interfaceScriptable
- Overrides:
delete
in classScriptableObject
- Parameters:
index
- the numeric index for the property- See Also:
Scriptable.get(int, Scriptable)
,ScriptableObject.deleteProperty(Scriptable, int)
-
getIds
public java.lang.Object[] getIds()
Description copied from class:ScriptableObject
Returns an array of ids for the properties of the object.Any properties with the attribute DONTENUM are not listed.
- Specified by:
getIds
in interfaceScriptable
- Overrides:
getIds
in classScriptableObject
- Returns:
- an array of java.lang.Objects with an entry for every listed property. Properties accessed via an integer index will have a corresponding Integer entry in the returned array. Properties accessed by a String will have a String entry in the returned array.
-
getBytesPerElement
public abstract int getBytesPerElement()
Return the number of bytes represented by each element in the array. This can be useful when wishing to manipulate the byte array directly from Java.
-
execIdCall
public java.lang.Object execIdCall(IdFunctionObject f, Context cx, Scriptable scope, Scriptable thisObj, java.lang.Object[] args)
Description copied from class:IdScriptableObject
'thisObj' will be null if invoked as constructor, in which case instance of Scriptable should be returned.- Specified by:
execIdCall
in interfaceIdFunctionCall
- Overrides:
execIdCall
in classIdScriptableObject
-
getArrayElement
public java.lang.Object getArrayElement(int index)
Description copied from interface:ExternalArrayData
Return the element at the specified index. The result must be a type that is valid in JavaScript: Number, String, or Scriptable. This method will not be called unless "index" is in range.- Specified by:
getArrayElement
in interfaceExternalArrayData
-
setArrayElement
public void setArrayElement(int index, java.lang.Object value)
Description copied from interface:ExternalArrayData
Set the element at the specified index. This method will not be called unless "index" is in range. The method must check that "value" is a valid type, and convert it if necessary.- Specified by:
setArrayElement
in interfaceExternalArrayData
-
