IdFunctionObject

public IdFunctionObject(IdFunctionCall idcall,
 Object tag,
 int id,
 String name,

 VarScope scope)

Method Details

initFunction

public void initFunction(String name,
 VarScope scope)

hasTag

public final boolean hasTag(Object tag)

getTag

public Object getTag()

methodId

public final int methodId()

markAsConstructor

public final void markAsConstructor(Scriptable prototypeProperty)

addAsProperty

public final <T extends PropHolder<T>> void addAsProperty(T target)

exportAsScopeProperty

public void exportAsScopeProperty()

getPrototype

public Scriptable getPrototype()

Description copied from class: ScriptableObject

Returns the prototype of the object.

Specified by:

getPrototype in interface Scriptable

Overrides:

getPrototype in class ScriptableObject

Returns:

the prototype

call

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

Overrides:

call in class BaseFunction

getThisObj

public final Scriptable getThisObj(Object thisObj)

construct

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

Description copied from interface: Constructable

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.

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

createObject

public Scriptable createObject(Context cx,
 VarScope scope)

Description copied from class: BaseFunction

Creates new script object. The default implementation of BaseFunction.construct(org.htmlunit.corejs.javascript.Context, java.lang.Object, org.htmlunit.corejs.javascript.VarScope, java.lang.Object[]) uses this method to to get the value for thisObj argument when invoking BaseFunction.call(org.htmlunit.corejs.javascript.Context, org.htmlunit.corejs.javascript.VarScope, java.lang.Object, java.lang.Object[]). The method is allowed to return null to indicate that BaseFunction.call(org.htmlunit.corejs.javascript.Context, org.htmlunit.corejs.javascript.VarScope, java.lang.Object, java.lang.Object[]) will create a new object itself. In this case BaseFunction.construct(org.htmlunit.corejs.javascript.Context, java.lang.Object, org.htmlunit.corejs.javascript.VarScope, java.lang.Object[]) will set scope and prototype on the result BaseFunction.call(org.htmlunit.corejs.javascript.Context, org.htmlunit.corejs.javascript.VarScope, java.lang.Object, java.lang.Object[]) unless they are already set.

Overrides:

createObject in class BaseFunction

getArity

public int getArity()

Overrides:

getArity in class BaseFunction

getLength

public int getLength()

Overrides:

getLength in class BaseFunction

isConstructor

public boolean isConstructor()

Description copied from interface: Function

Return whether this function can be called as a constructor.

Specified by:

isConstructor in interface Function

Overrides:

isConstructor in class BaseFunction

getFunctionName

public String getFunctionName()

Overrides:

getFunctionName in class BaseFunction

unknown

public final RuntimeException unknown()
