public class CompactNodeTypeDefReader<T,N>
extends Object

CompactNodeTypeDefReader. Parses node type definitions written in the compact node type definition format and provides a list of type definition objects that can then be used to register node types.

The CompactNodeTypeDefReader is parameterizable in the type of the node type definition T and the type of the namespace mapping N which the parser should build. For types T and N the parser's constructor takes a DefinitionBuilderFactory for T and N.

The EBNF grammar of the compact node type definition:
