Method Details

getClassName

public 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

execIdCall

public Object execIdCall(IdFunctionObject f,
 Context cx,
 Scriptable scope,
 Scriptable thisObj,
 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 interface IdFunctionCall

Overrides:

execIdCall in class IdScriptableObject

get

public 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 interface Scriptable

Overrides:

get in class ScriptableObject

Parameters:

index - the numeric index for the property

start - 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 interface Scriptable

Overrides:

has in class ScriptableObject

Parameters:

index - the numeric index for the property

start - 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(String id,
 Scriptable start,
 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 IdScriptableObject

Parameters:

id - the name of the property

start - the object whose property is being set

value - value to set the property to

See Also:

• Scriptable.has(String, Scriptable)
• Scriptable.get(String, Scriptable)
• ScriptableObject.putProperty(Scriptable, String, Object)
• Context.toObject(Object, Scriptable)

put

public void put(int index,
 Scriptable start,
 Object value)

Description copied from class: ScriptableObject

Sets the value of the indexed property, creating it if need be.

Specified by:

put in interface Scriptable

Overrides:

put in class ScriptableObject

Parameters:

index - the numeric index for the property

start - the object whose property is being set

value - 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 interface Scriptable

Overrides:

delete in class ScriptableObject

Parameters:

index - the numeric index for the property

See Also:

• Scriptable.get(int, Scriptable)
• ScriptableObject.deleteProperty(Scriptable, int)

getIds

public 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.

getAllIds

public Object[] getAllIds()

Description copied from class: ScriptableObject

Returns an array of ids for the properties of the object.

All properties, even those with attribute DONTENUM, are listed.

Specified by:

getAllIds in interface DebuggableObject

Overrides:

getAllIds 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.

getIndexIds

public Integer[] getIndexIds()

getDefaultValue

public Object getDefaultValue(Class<?> hint)

Description copied from class: ScriptableObject

Implements the [[DefaultValue]] internal method.

Note that the toPrimitive conversion is a no-op for every type other than Object, for which [[DefaultValue]] is called. See ECMA 9.1.

A hint of null means "no hint".

Specified by:

getDefaultValue in interface Scriptable

Overrides:

getDefaultValue in class ScriptableObject

Parameters:

hint - the type hint

Returns:

the default value for the object See ECMA 8.6.2.6.

getAttributes

public int getAttributes(int index)

Description copied from class: ScriptableObject

Get the attributes of an indexed property.

Overrides:

getAttributes in class ScriptableObject

Parameters:

index - the numeric index for the property

Returns:

the bitset of attributes

• ScriptableObject.has(String, Scriptable)
• ScriptableObject.READONLY
• ScriptableObject.DONTENUM
• ScriptableObject.PERMANENT
• ScriptableObject.EMPTY
