public abstract Class AbstractPathResolver

This Resolver is responsible to resolve a single path of a path expression (state field path expression, singled valued object field, or a collection-valued path expression).

Field Summary

private IManagedType	managedType The `IManagedType` representing this single valued object field path.
private boolean	managedTypeResolved This flag is used to prevent resolving the `IManagedType` more than once and no managed type could be found the first time.
private IMapping	mapping The mapping of the last path of the path expression or `null` if it could not be found.
private boolean	mappingResolved This flag is used to prevent resolving the `IMapping` more than once and no mapping could be found the first time.
protected final String	path The name of the path for which its type will be retrieved.
