Interface PropertiesFilter
- All Known Implementing Classes:
- ButtonPropertiesFilter, CompositeButtonPropertiesFilter, GlobalButtonPropertiesFilter, TabBarPropertiesFilter
- public interface PropertiesFilter
The PropertiesFilter interface is designed to allow type-specific
filtering to be performed on the client-provided "requested" properties
prior to rendering an image. Filtering might be performed to enhance
or modify the client-provided properties. For example, the filter
might add type-specific default values for properties that are not
specified by the client. Type-specific filters are registered and
retrieved from ImageType instances using the PROPERTIES_FILTER_PROPERTY
key.
