    • getClassName

      public String getClassName()
      Description copied from interface: Scriptable
      Get the name of the set of objects implemented by this Java class. This corresponds to the [[Class]] operation in ECMA and is used by Object.prototype.toString() in ECMA.

      See ECMA 8.6.2 and 15.2.4.2.

      Specified by:
      getClassName in interface Scriptable
      Overrides:
      getClassName in class NativeJavaObject

    • has

      public boolean has(String name, Scriptable start)
      Description copied from interface: Scriptable
      Indicates whether or not a named property is defined in an object. Does not traverse the prototype chain.

      The property is specified by a String name as defined for the get method.

      Specified by:
      has in interface Scriptable
      Overrides:
      has in class NativeJavaObject
      Parameters:
      name - the name of the property
      start - the object in which the lookup began
      Returns:
      true if and only if the named property is found in the object
      See Also:

    • has

      public boolean has(int index, Scriptable start)
      Description copied from interface: Scriptable
      Indicates whether or not an indexed property is defined in an object. Does not traverse the prototype chain.

      The property is specified by an integral index as defined for the get method.

      Specified by:
      has in interface Scriptable
      Overrides:
      has in class NativeJavaObject
      Parameters:
      index - the numeric index for the property
      start - the object in which the lookup began
      Returns:
      true if and only if the indexed property is found in the object
      See Also:

    • has

      public boolean has(Symbol key, Scriptable start)
      Description copied from interface: SymbolScriptable
      Return true if the specified property exists.
      Specified by:
      has in interface SymbolScriptable
      Overrides:
      has in class NativeJavaObject

    • get

      public Object get(String name, Scriptable start)
      Description copied from interface: Scriptable
      Get a named property from the object. Looks property up in this object and returns the associated value if found. Returns NOT_FOUND if not found. Note that this method is not expected to traverse the prototype chain. This is different from the ECMA [[Get]] operation. Depending on the property selector, the runtime will call this method or the form of get that takes an integer:
      JavaScript codeJava code
      a.b a.get("b", a)
      a["foo"] a.get("foo", a)
      a[3] a.get(3, a)
      a["3"] a.get(3, a)
      a[3.0] a.get(3, a)
      a["3.0"] a.get("3.0", a)
      a[1.1] a.get("1.1", a)
      a[-4] a.get(-4, a)

      The values that may be returned are limited to the following:

      • java.lang.Boolean objects
      • java.lang.String objects
      • java.lang.Number objects
      • org.mozilla.javascript.Scriptable objects
      • null
      • The value returned by Context.getUndefinedValue()
      • NOT_FOUND
      Specified by:
      get in interface Scriptable
      Overrides:
      get in class NativeJavaObject
      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

    • get

      public Object get(int index, Scriptable start)
      Description copied from interface: Scriptable
      Get a property from the object selected by an integral index. Identical to get(String, Scriptable) except that an integral index is used to select the property.
      Specified by:
      get in interface Scriptable
      Overrides:
      get in class NativeJavaObject
      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:

    • get

      public Object get(Symbol key, Scriptable start)
      Description copied from interface: SymbolScriptable
      Return the value of the property with the specified key, or NOT_FOUND.

    • put

      public void put(int index, Scriptable start, Object value)
      Description copied from interface: Scriptable
      Sets an indexed property in this object.

      The property is specified by an integral index as defined for get.

      Identical to put(String, Scriptable, Object) except that an integral index is used to select the property.

      Specified by:
      put in interface Scriptable
      Overrides:
      put in class NativeJavaObject
      Parameters:
      index - the numeric index for the property
      start - the object whose property is being set
      value - value to set the property to

    • getIds

      public Object[] getIds()
      Description copied from interface: Scriptable
      Get an array of property ids. Not all property ids need be returned. Those properties whose ids are not returned are considered non-enumerable.
      Specified by:
      getIds in interface Scriptable
      Overrides:
      getIds in class NativeJavaObject
      Returns:
