Method Detail

onPreAdd

public void onPreAdd(IoFilterChain parent,
                     java.lang.String name,
                     IoFilter.NextFilter nextFilter)
              throws java.lang.Exception

Description copied from interface: IoFilter

Invoked before this filter is added to the specified parent. Please note that this method can be invoked more than once if this filter is added to more than one parents. This method is not invoked before IoFilter.init() is invoked.

Specified by:

onPreAdd in interface IoFilter

Overrides:

onPreAdd in class IoFilterAdapter

Parameters:

parent - the parent who called this method

name - the name assigned to this filter

nextFilter - the IoFilter.NextFilter for this filter. You can reuse this object until this filter is removed from the chain.

Throws:

java.lang.Exception

onPostRemove

public void onPostRemove(IoFilterChain parent,
                         java.lang.String name,
                         IoFilter.NextFilter nextFilter)
                  throws java.lang.Exception

Description copied from interface: IoFilter

Invoked after this filter is removed from the specified parent. Please note that this method can be invoked more than once if this filter is removed from more than one parents. This method is always invoked before IoFilter.destroy() is invoked.

Specified by:

onPostRemove in interface IoFilter

Overrides:

onPostRemove in class IoFilterAdapter

Parameters:

parent - the parent who called this method

name - the name assigned to this filter
