Constructor Detail

RowCountChangeEvent

protected RowCountChangeEvent(int rowCount,
                   boolean isExact)

Creates a RowCountChangeEvent.

Parameters:

rowCount - the new row count

isExact - true if the row count is exact

Method Detail

fire

public static void fire(HasRows source,
        int rowCount,
        boolean isExact)

Fires a RowCountChangeEvent on all registered handlers in the handler manager. If no such handlers exist, this method will do nothing.

Parameters:

source - the source of the handlers

rowCount - the new rowCount

isExact - true if rowCount is an exact count

getType

public static GwtEvent.Type<RowCountChangeEvent.Handler> getType()

Gets the type associated with this event.

Returns:

returns the handler type

getAssociatedType

public final GwtEvent.Type<RowCountChangeEvent.Handler> getAssociatedType()

Description copied from class: Event

Returns the Event.Type used to register this event, allowing an EventBus to find handlers of the appropriate class.

Specified by:

getAssociatedType in class GwtEvent<RowCountChangeEvent.Handler>

Returns:

the type

getNewRowCount

public int getNewRowCount()

Gets the new row count.

Returns:

the new row count

isNewRowCountExact

public boolean isNewRowCountExact()

Check if the new row count is exact.

Returns:

true if the new row count is exact, false if not

toDebugString

public String toDebugString()

Description copied from class: Event

This is a method used primarily for debugging. It gives a string representation of the event details. This does not override the toString method because the compiler cannot always optimize toString out correctly. Event types should override as desired.

Overrides:

toDebugString in class Event<RowCountChangeEvent.Handler>

Returns:

a string representing the event's specifics.

dispatch

protected void dispatch(RowCountChangeEvent.Handler handler)

Description copied from class: GwtEvent

Should only be called by HandlerManager. In other words, do not use or call.

Specified by:

dispatch in class GwtEvent<RowCountChangeEvent.Handler>

Parameters:

handler - handler
