public void init(IJSpace space, String filterId, String url, int priority) throws RuntimeException
init
in interface ISpaceFilter
space
- an embedded proxy to the space that contain this filter.filterId
- the name of this filter.url
- The URL that was passed when this filter was created.priority
- defines the order in which filters are activated.
RuntimeException
- if this exception is raised, the filter will
be discarded by the engine for the current engine execution ,unless defined otherwise in space configuration.public void initSpaceUserAccountDriver(String spaceName, String url, String containerName) throws Exception
spaceName
- url
- containerName
-
Exception
public void process(SpaceContext context, ISpaceFilterEntry[] subject, int operationCode) throws RuntimeException
process
in interface ISpaceFilter
context
- the Context passed by the caller, contains
security context. some of the filters (like ON_INIT) will always
receive a null context.subject
- an array of two elements:
On BEFORE_UPDATE
: the first element
represents the template and the second is the new entry (can only happen when
replace
is called).
On AFTER_UPDATE
: the first element
represents the old entry while the second is the new entry.
On BEFORE_NOTIFY_TRIGGER
and AFTER_NOTIFY_TRIGGER
:
the first element represents the entry while the second is the template.
operationCode
- the operation that defines when this filter is activated.
The operation codes are defined in FilterOperationCodes
.
RuntimeException
- if this exception is raised for BEFORE filters,public void process(SpaceContext context, ISpaceFilterEntry subject, int operationCode) throws RuntimeException
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().
process
in interface ISpaceFilter
context
- the Context passed by the caller, contains
security context. some of the filters (like ON_INIT) will always
receive a null context.subject
- the event that occurred.operationCode
- the operation that defines when this filter is activated.
The operation codes are defined in FilterOperationCodes
.
RuntimeException
- if this exception is raised for BEFORE filters,
it aborts the execution of the operation.public void close() throws RuntimeException
close
in interface ISpaceFilter
RuntimeException
- if this exception is raised it will be logged.
This should be used as away to report a filter internal error.
