org.glassfish.grizzly.filterchain.Filter
A Filter encapsulates a unit of processing work to be performed, whose purpose is to examine and/or modify the state of a transaction that is represented by a {@link FilterChainContext}. Individual Filter can be assembled into a {@link FilterChain}, which allows them to either complete the required processing or delegate further processing to the next Filter in the {@link FilterChain}. Filter implementations should be designed in a thread-safe manner, suitable for inclusion in multiple {@link FilterChain} that might be processed by different threads simultaneously. In general, this implies that Filter classes should not maintain state information in instance variables. Instead, state information should be maintained via suitable modifications to the attributes of the {@link FilterChainContext} that is passed to theappropriate {@link Filter} processing methods.Filter implementations typically retrieve and store state information in the {@link FilterChainContext} instance that is passed as a parameterto the appropriate {@link Filter} processing methods,using particular {@link Attribute}s that can be acquired via {@link Attribute#get(org.glassfish.grizzly.attributes.AttributeStorage)} method. @see FilterChain @see Attribute @author Jeanfrancois Arcand @author Alexey Stashok
