| <h6 class=CaptionFigColumn id=header>Description: </h6>A symbol source provider is called to discover EL namespace variable symbols. For example, managed bean variable symbols, are contributed through a symbol source provider. A symbol source provider may or may not wish to use a context symbol factory depending on the situation. |
| |
| When an EL variable is resolved, each symbol provider will be considered equally. All of the information that determines a symbol's characteristics must be encoded in the returned ISymbol object. |
| |
| A list of registered symbol providers may be found by calling SymbolsPlugin.getSymbolSourceProvider().</p> |
