ResourceFilter
public ResourceFilter()
getTargetResource
public Resource getTargetResource()
- Get our target resource.
lookup
public boolean lookup(LookupState ls,
LookupResult lr) throws ProtocolException
- Lookup time filtering.
This method is called while Jigsaw performs resource lookup. Each time
a lookup end up on the target resource of that filter, this method
will be called.
- Parameters:
- ls - The current lookup state.
- lr - The current lookup result.
- Returns:
- A boolean, true if this filter has performed
the whole lookup, and side-effect the lookup result appropriatelly,
false otherwise.
- Throws: ProtocolException
- If processing should be interrupted,
because an abnormal situation occured.
- Overrides:
- lookup in class ResourceFrame
ingoingFilter
public ReplyInterface ingoingFilter(RequestInterface request) throws ProtocolException
- Simplified ingoingFilter API.
This is a default, simplified API to the ingoing filter method.
- Parameters:
- request - The request to filter.
- Returns:
- A Reply instance, or null if processing
should continue normally.
- Throws: ProtocolException
- If processing should be interrupted,
because an abnormal situation occured.
ingoingFilter
public ReplyInterface ingoingFilter(RequestInterface request,
FilterInterface filters[],
int i) throws ProtocolException
- The ingoingFilter method.
This is the method that really gets called by Jigsaw core. By default
it will invoke the simpler
ingoingFilter
method,
taking only the request has a parameter.
- Parameters:
- request - The request that is about to be handled.
- filters - The whole filter list to be applied to the resource.
- i - A pointer into the above array, indicating which filters
have already been triggered (the one whose index are lower than
i), and what filters have to be triggered (the one
whose index are greater or equal to i+1).
- Returns:
- A Reply instance, if the filter did know how to answer
the request without further processing, null
otherwise.
- Throws: ProtocolException
- If processing should be interrupted,
because an abnormal situation occured.
outgoingFilter
public ReplyInterface outgoingFilter(RequestInterface request,
ReplyInterface reply) throws ProtocolException
- Simplified API to the outgoing filter metho.
This is a simplified API to the ougoing filter method, you can either
overide this method, or the more powerfull one.
- Parameters:
- request - The original request.
- reply - It's original reply.
- Returns:
- A Reply instance, or null if processing
should continue normally.
- Throws: ProtocolException
- If processing should be interrupted,
because an abnormal situation occured.
exceptionFilter
public ReplyInterface exceptionFilter(RequestInterface request,
ProtocolException ex,
FilterInterface filters[],
int i)
outgoingFilter
public ReplyInterface outgoingFilter(RequestInterface request,
ReplyInterface reply,
FilterInterface filters[],
int fidx) throws ProtocolException
- The outgoingFilter method.
This method is the one that gets called by Jigsaw core. By default it
will call the simpler
outgoingFilter
method that takes
only the request and the reply as parameters.
- Parameters:
- request - The request that has been processed.
- reply - The original reply as emitted by the resource.
- filters - The whole filter that applies to the resource.
- i - The current index of filters. The i filter is ourself,
filters with lower indexes have already been applied, and filters with
greater indexes are still to be applied.
- Returns:
- A Reply instance, if that filter know how to complete the
request processing, or null if reminaing filters
are to be called by Jigsaw engine.
- Throws: ProtocolException
- If processing should be interrupted,
because an abnormal situation occured.
outputFilter
public OutputStream outputFilter(RequestInterface request,
ReplyInterface reply,
OutputStream output)
