Examples of org.apache.tiles.definition.DefinitionsReader

org.apache.tiles.definition.DefinitionsReader
Interface for reading {@link Definition} from a source.

This interface provides a standard way to read {@link Definition} objects from a source. Implementations should define what the source is, whether it be a persistent store such as a configuration file or database, or something like a web service. The DefinitionsReader is responsible for reading from a single location. It does not perform any internationalization duties or inheritance of Definitions. It only reads from the source and returns a Map of objects read.
