toArrayIndex

private static long toArrayIndex(Object id)

toArrayIndex

private static long toArrayIndex(String id)

toArrayIndex

private static long toArrayIndex(double d)

toDenseIndex

private static int toDenseIndex(Object id)

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

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:
