Package javax.microedition.broadcast.esg Description

This package defines the classes and interfaces to access the Electronic Service Guide (ESG).

ESG is modeled by a ServiceGuide class. Concept of ESG is explained in its documentation. Application can compose queries to query programs and services from the ESG. ProgramEvent and Service extend ServiceGuideData which is the base interface to provide information from ESG. For some given Attribute the information is returned by ServiceGuideData as boolean, Date, Double, Long, Object or String, or an array of them. Available attributes are specified in MetadataSets. CommonMetadataSet contains a predefined set of attributes that is supported by all implementations.
