Method Detail

getClassName

public java.lang.String getClassName()

Description copied from class: ScriptableObject

Return the name of the class. This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.

Specified by:

getClassName in interface Scriptable

Specified by:

getClassName in class ScriptableObject

get

public java.lang.Object get(java.lang.String name,
                            Scriptable start)

Description copied from class: ScriptableObject

Returns the value of the named property or NOT_FOUND. If the property was created using defineProperty, the appropriate getter method is called.

Specified by:

get in interface Scriptable

Overrides:

get in class ScriptableObject

Parameters:

name - the name of the property

start - the object in which the lookup began

Returns:

the value of the property (may be null), or NOT_FOUND

put

public void put(java.lang.String name,
                Scriptable start,
                java.lang.Object value)

Description copied from class: ScriptableObject

Sets the value of the named property, creating it if need be. If the property was created using defineProperty, the appropriate setter method is called.

If the property's attributes include READONLY, no action is taken. This method will actually set the property in the start object.

Specified by:

put in interface Scriptable

Overrides:

put in class ScriptableObject

Parameters:

name - the name of the property

start - the object whose property is being set

value - value to set the property to

delete

public void delete(java.lang.String name)

Description copied from class: ScriptableObject

Removes a named property from the object. If the property is not found, or it has the PERMANENT attribute, no action is taken.

Specified by:

delete in interface Scriptable

Overrides:

delete in class ScriptableObject

Parameters:

name - the name of the property

Scriptable.get(String, Scriptable), ScriptableObject.deleteProperty(Scriptable, String)

has

public boolean has(java.lang.String name,
                   Scriptable start)

Description copied from class: ScriptableObject

Returns true if the named property is defined.

Specified by:

Parameters:

name - the name of the property

start - the object in which the lookup began

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 interface Scriptable

Overrides:

getIds in class ScriptableObject

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.
