Interface RelOps

All Known Implementing Classes:

SDArray, SDByte, SDFloat32, SDFloat64, SDGrid, SDInt16, SDInt32, SDList, SDSequence, SDString, SDStructure, SDUInt16, SDUInt32, SDURL

public interface RelOps

The RelOps interface defines how each type responds to relational operators. Most (all?) types will not have sensible responses to all of the relational operators (e.g. DByte won't know how to match a regular expression but DString will). For those operators that are nonsensical a class should throw InvalidOperator.
