public interface ConstProperties
| Modifier and Type | Method and Description | 
|---|---|
| void | defineConst(java.lang.String name,
           Scriptable start)Reserves a definition spot for a const. | 
| boolean | isConst(java.lang.String name)Returns true if the named property is defined as a const on this object. | 
| void | putConst(java.lang.String name,
        Scriptable start,
        java.lang.Object value)Sets a named const property in this object. | 
void putConst(java.lang.String name,
              Scriptable start,
              java.lang.Object value)
 The property is specified by a string name
 as defined for Scriptable.get.
 
 The possible values that may be passed in are as defined for
 Scriptable.get. A class that implements this method may choose
 to ignore calls to set certain properties, in which case those
 properties are effectively read-only.
 For properties defined in a prototype chain,
 use putProperty in ScriptableObject. 
 Note that if a property a is defined in the prototype p
 of an object o, then evaluating o.a = 23 will cause
 set to be called on the prototype p with
 o as the  start parameter.
 To preserve JavaScript semantics, it is the Scriptable
 object's responsibility to modify o. 
This design allows properties to be defined in prototypes and implemented in terms of getters and setters of Java values without consuming slots in each instance.
The values that may be set are limited to the following:
 Arbitrary Java objects may be wrapped in a Scriptable by first calling
 Context.toObject. This allows the property of a JavaScript
 object to contain an arbitrary Java object as a value.
 Note that has will be called by the runtime first before
 set is called to determine in which object the
 property is defined.
 Note that this method is not expected to traverse the prototype chain,
 which is different from the ECMA [[Put]] operation.
