filter

public Filterable filter(String fieldId,
                         Filterable source)

Specified by:

filter in interface Filter

Overrides:

filter in class ContextFilter

filter

public Collection filter(String fieldId,
                         Collection source)

Description copied from class: ContextFilter

iterates over the contents of the collection and filters each. Adds itself to the context. This is somewhat dangerous.

Specified by:

filter in interface Filter

Overrides:

filter in class ContextFilter

filter

public Map filter(String fieldId,
                  Map source)

Description copied from class: ContextFilter

filters both the key and value sets of the map. Adds itself to the context. Somewhat dangerous.

Specified by:

filter in interface Filter

Overrides:

filter in class ContextFilter

findClass
