public interface MultipleMappingSubstitutionMap
extends SubstitutionMap

MultipleMappingSubstitutionMap is a special type of SubstitutionMap that can create multiple mappings for a single lookup. This is particularly important with respect to CSS renaming.

For example, a SplittingSubstitutionMap may rename "goog-component" as "a-b", in which case it has created two renaming mappings: "a" -> "goog" and "b" -> "component", both of which are necessary to produce the full renaming map.

Note that in the case of SplittingSubstitutionMap, the map that is returned by getValueWithMappings(String) does not contain "goog-component" as a key because the entries "goog" and "component" are sufficient to construct the renamed version of "goog-component". Therefore, the key passed into getValueWithMappings(String) is not guaranteed to appear in the output.

Method Detail

getValueWithMappings

MultipleMappingSubstitutionMap.ValueWithMappings getValueWithMappings(java.lang.String key)

Like an ordinary SubstitutionMap, this returns a value to substitute for the specified key. This value is available as MultipleMappingSubstitutionMap.ValueWithMappings.value.

Additionally, it also returns any renaming mappings that should be associated with this substitution. These mappings are available as MultipleMappingSubstitutionMap.ValueWithMappings.mappings.
