Constructor Details

JavaConstructorObject

public JavaConstructorObject(String name,
 JavaClassWrapper classWrapper)

Constructor for JavaConstructorObject.

Parameters:

name - a String object.

classWrapper - a JavaClassWrapper object.

JavaConstructorObject

public JavaConstructorObject(String name,
 JavaClassWrapper classWrapper,
 JavaInstantiator instantiator)

Constructor for JavaConstructorObject.

Parameters:

name - a String object.

classWrapper - a JavaClassWrapper object.

instantiator - a JavaInstantiator object.

Method Details

call

public Object call(Context cx,
 Scriptable scope,
 Scriptable thisObj,
 Object[] args)

Call the function.

Note that the array of arguments is not guaranteed to have length greater than 0.

Specified by:

call in interface Callable

Specified by:

call in interface Function

Parameters:

cx - the current Context for this thread

scope - the scope to execute the function relative to. This is set to the value returned by getParentScope() except when the function is called from a closure.

thisObj - the JavaScript this object

args - the array of arguments

Returns:

the result of the call

construct

public Scriptable construct(Context cx,
 Scriptable scope,
 Object[] args)

Call the function as a constructor.

This method is invoked by the runtime in order to satisfy a use of the JavaScript new operator. This method is expected to create a new object and return it.

Specified by:

construct in interface Constructable

Specified by:

construct in interface Function

Parameters:

cx - the current Context for this thread

scope - an enclosing scope of the caller except when the function is called from a closure.

args - the array of arguments

Returns:

the allocated object

getClassName

public String getClassName()

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

getDefaultValue

public Object getDefaultValue(Class<?> hint)

Implements the [[DefaultValue]] internal method.

Note that the toPrimitive conversion is a no-op for every type other than Object, for which [[DefaultValue]] is called. See ECMA 9.1.

A hint of null means "no hint".

Specified by:

getDefaultValue in interface Scriptable

Overrides:

getDefaultValue in class ScriptableObject

Parameters:

hint - the type hint

Returns:

the default value for the object

See ECMA 8.6.2.6.
