public interface DefinitionsReader

Interface for reading Definition from a source.

This interface provides a standard way to read 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.

Parameters:

params - A map of properties used to set up the reader.

Throws:

DefinitionsFactoryException - if required properties are not passed in or the initialization fails.

read

Map<String,Definition> read(Object source)

Reads Definition objects from a source.

Implementations should publish what type of source object is expected.

Parameters:

Returns:

a Map of Definition objects read from the source.

Throws:

DefinitionsFactoryException - if the source is invalid or an error occurs when reading definitions.
