init

public void init(IJSpace space,
 String filterId,
 String url,

process

public void process(SpaceContext context,
 ISpaceFilterEntry entry,
 int operationCode)
             throws RuntimeException

Description copied from interface: ISpaceFilter

 This method is called by the engine when an event matching this filter's
  operation code occurs in the space engine.

 Only for SecurityFilter implementation: On SET_SECURITY operation code call
 SpaceContext.setSecurityContext().
 

Specified by:

process in interface ISpaceFilter

Parameters:

context - the Context passed by the caller, contains security context. some of the filters (like ON_INIT) will always receive a null context.

entry - the event that occurred.

operationCode - the operation that defines when this filter is activated. The operation codes are defined in FilterOperationCodes.

Throws:

RuntimeException - if this exception is raised for BEFORE filters, it aborts the execution of the operation.

process

public void process(SpaceContext context,
 ISpaceFilterEntry[] entries,
 int operationCode)
             throws RuntimeException

Description copied from interface: ISpaceFilter

This method is called by the engine when an event matching this filter's operation code occurs in the engine.

Notice: This is a special case that is called only on update() only on AFTER_UPDATE.
Also on BEFORE_NOTIFY_TRIGGER and AFTER_NOTIFY_TRIGGER.

Specified by:

process in interface ISpaceFilter

Parameters:

context - the Context passed by the caller, contains security context. some of the filters (like ON_INIT) will always receive a null context.
