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

Overrides:

getClassName in class NativeJavaObject

has

public boolean has(java.lang.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:

Scriptable.get(String, Scriptable), ScriptableObject.getProperty(Scriptable, String)

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)

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 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 code	Java 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

Scriptable.get(String,Scriptable)

get

public java.lang.Object get(Symbol key,
                            Scriptable start)

Description copied from interface: SymbolScriptable

Return the value of the property with the specified key, or NOT_FOUND.

Specified by:

get in interface SymbolScriptable

Overrides:

get in class NativeJavaObject

put

public void put(int index,
                Scriptable start,
                java.lang.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 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
