IdFunctionObject

public IdFunctionObject(IdFunctionCall idcall,

Method Details

initFunction

public void initFunction(String name,
 Scriptable 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 void addAsProperty(Scriptable 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,
 Scriptable scope,
 Scriptable thisObj,
 Object[] args)

Description copied from class: BaseFunction

Should be overridden.

Specified by:

call in interface Callable

Specified by:

call in interface Function

Overrides:

call in class BaseFunction

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

createObject

public Scriptable createObject(Context cx,
 Scriptable scope)

Description copied from class: BaseFunction

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

getFunctionName

public String getFunctionName()

Overrides:

getFunctionName in class BaseFunction

unknown

public final RuntimeException unknown()
