## Class BindingsObject

- java.lang.Object
- - org.mozilla.javascript.ScriptableObject
  - - org.mozilla.javascript.engine.BindingsObject

- All Implemented Interfaces:
    `java.io.Serializable`, `ConstProperties`, `DebuggableObject`, `Scriptable`, `SymbolScriptable`

      public class BindingsObject
      extends ScriptableObject

  This class makes the Bindings object into a Scriptable. That way, we can query and modify the contents of the Bindings on demand.

- - ### 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
      See Also:
        `Context.getUndefinedValue()`

    - #### 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
      See Also:
        `Scriptable.has(String, Scriptable)`, `Scriptable.get(String, Scriptable)`, `ScriptableObject.putProperty(Scriptable, String, Object)`, `Context.toObject(Object, Scriptable)`

    - #### 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
      See Also:
        `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:
        `has` in interface `Scriptable`
      Overrides:
        `has` in class `ScriptableObject`
      Parameters:
        `name` - the name of 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(String, Scriptable)`, `ScriptableObject.getProperty(Scriptable, String)`

    - #### 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.
