public class TypeInfo

extends java.lang.Object

The TypeInfo class provides meta-info regarding the data available from a given source. Data is assumed to be organized into objects that have a name and various fields, each of which has a name and is either a scalar or a vector field. The TypeInfo object mirrors this structure by maintaining a list of ObjectInfo objects that each contain DataField objects. TypeInfo also provides utility methods for accessing its information.
