standardPlugins

public static final Map<String,QParserPlugin> standardPlugins

Internal use - name to parser for the builtin parsers. Each query parser plugin extending QParserPlugin has own instance of standardPlugins. This leads to cyclic dependencies of static fields and to case when NAME field is not yet initialized. This result to NPE during initialization. For every plugin, listed here, NAME field has to be final and static.
