Examples of PathSpec

com.linkedin.data.schema.PathSpec
A PathSpec represents a path within a complex data object. PathSpecs may be obtained from generated RecordTemplate subclasses using the .fields() method. Because the primary use cases for PathSpecs are to generate uniform references in hierarchical data maps (used in the data-transform) component, the path segments are all represented as String, including the representation for wildcards and integer array indices. @author Josh Walker @version $Revision: $

The base PathSpec, what all other path specs are based on
