Method Detail

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

setPrototype

public void setPrototype(Scriptable p)

Description copied from class: ScriptableObject

Sets the prototype of the object.

Specified by:

setPrototype in interface Scriptable

Overrides:

setPrototype in class ScriptableObject

Parameters:

p - the prototype to set

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 ScriptableObject

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(boolean nonEnumerable,
                       boolean getSymbols)

getIndexIds

public List<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

See Also:

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

getOwnPropertyDescriptor

protected ScriptableObject getOwnPropertyDescriptor(Context cx,
                                                    Object id)

Overrides:

getOwnPropertyDescriptor in class ScriptableObject

defineOwnProperty

protected boolean defineOwnProperty(Context cx,
                                    Object id,
                                    ScriptableObject desc,
                                    boolean checkValid)

Description copied from class: ScriptableObject

Defines a property on an object.

Based on [[DefineOwnProperty]] from 8.12.10 of the spec. see [[DefineOwnProperty]]
