    • Method Detail

      • getClassName

        public java.lang.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

      • 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:
        Scriptable.get(int, Scriptable), ScriptableObject.getProperty(Scriptable, int)

      • get

        public java.lang.Object get​(java.lang.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
        See Also:
        Context.getUndefinedValue()

      • get

        public java.lang.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:
        Scriptable.get(String,Scriptable)

      • put

        public void put​(java.lang.String name,
                Scriptable start,
                java.lang.Object value)
        Description copied from interface: Scriptable
        Sets a named property in this object.

        The property is specified by a string name as defined for get.

        The possible values that may be passed in are as defined for 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:

        • java.lang.Boolean objects
        • java.lang.String objects
        • java.lang.Number objects
        • org.mozilla.javascript.Scriptable objects
        • null
        • The value returned by Context.getUndefinedValue()

        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.

        put in interface Scriptable
        Overrides:
        put in class NativeJavaObject
        Parameters:
        name - the name of the property
        start - the object whose property is being set
        value - value to set the property to

      • getIds

        public java.lang.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:
        an array of Objects. Each entry in the array is either a java.lang.String or a java.lang.Number
