Method Details

getFunctionName

public String getFunctionName()

Overrides:

getFunctionName in class BaseFunction

getLength

public int getLength()

Overrides:

getLength in class BaseFunction

getArity

public int getArity()

Overrides:

getArity in class BaseFunction

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

construct

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

Description copied from interface: Function

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

Overrides:

construct in class BaseFunction

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

getImpl

private static RegExpImpl getImpl()

getMaxInstanceId

protected int getMaxInstanceId()

Description copied from class: IdScriptableObject

Get maximum id findInstanceIdInfo can generate.

Overrides:

getMaxInstanceId in class BaseFunction

findInstanceIdInfo

protected int findInstanceIdInfo(String s)

Description copied from class: IdScriptableObject

Map name to id of instance property. Should return 0 if not found or the result of IdScriptableObject.instanceIdInfo(int, int).

Overrides:

findInstanceIdInfo in class BaseFunction

getInstanceIdName

protected String getInstanceIdName(int id)

Description copied from class: IdScriptableObject

Map id back to property name it defines.

Overrides:

getInstanceIdName in class BaseFunction

getInstanceIdValue

protected Object getInstanceIdValue(int id)

Description copied from class: IdScriptableObject

Get id value. * If id value is constant, descendant can call cacheIdValue to store * value in the permanent cache. * Default implementation creates IdFunctionObject instance for given id * and cache its value

Overrides:

getInstanceIdValue in class BaseFunction

setInstanceIdValue

protected void setInstanceIdValue(int id,
 Object value)

Description copied from class: IdScriptableObject

Set or delete id value. If value == NOT_FOUND , the implementation should make sure that the following getInstanceIdValue return NOT_FOUND.

Overrides:

setInstanceIdValue in class BaseFunction

setInstanceIdAttributes

protected void setInstanceIdAttributes(int id,
 int attr)

Description copied from class: IdScriptableObject

Update the attributes of the given instance property. Classes which want to support changing property attributes via Object.defineProperty must override this method. The default implementation throws InternalError.

Overrides:

setInstanceIdAttributes in class BaseFunction

Parameters:

id - the instance property id

attr - the new attribute bitset
