Symbol Source Provider

Identifier:
org.eclipse.jst.jsf.common.symbols

Since:
1.5

Description:
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 JSFCommonPlugin.getSymbolSourceProvider().

Configuration Markup:

<!ELEMENT extension ( symbolSourceId)>

<!ATTLIST extension

point CDATA #REQUIRED

id    CDATA #IMPLIED

name  CDATA #IMPLIED

<!ELEMENT symbolSourceId EMPTY>

factory CDATA #REQUIRED

  • factory - An instance of the factory interface that will be invoked to create an instance of this symbol source provider. Factory must have a zero-arg default constructor.

Examples:
The following xml is used to contribute a set of default providers to contribute managed bean, built-in and tag contributed variables:


   <extension
         point=
"org.eclipse.jst.jsf.context.symbol.symbolSourceProvider"
>
      <symbolSourceId factory=
"org.eclipse.jst.jsf.designtime.internal.symbols.DefaultBeanSymbolSourceProvider"
/>
      <symbolSourceId factory=
"org.eclipse.jst.jsf.designtime.internal.symbols.JSPTagVariableSymbolSourceProvider"
/>
      <symbolSourceId factory=
"org.eclipse.jst.jsf.designtime.internal.symbols.DefaultBuiltInSymbolProvider"
/>
   </extension>
