Class ThriftValidation

java.lang.Object
  org.apache.cassandra.thrift.ThriftValidation

public class ThriftValidation
extends java.lang.Object

This has a lot of building blocks for CassandraServer to call to make sure it has valid input -- ensuring column names conform to the declared comparator, for instance. The methods here mostly try to do just one part of the validation so they can be combined for different needs -- supercolumns vs regular, range slices vs named, batch vs single-column. (ValidateColumnPath is the main exception in that it includes table and CF validation.)
