Examples of org.apache.derby.iapi.types.SQLVarchar

org.apache.derby.iapi.types.SQLVarchar
SQLVarchar satisfies the DataValueDescriptor interfaces (i.e., OrderableDataType). It implements a String holder, e.g. for storing a column value; it can be specified when constructed to not allow nulls. Nullability cannot be changed after construction.
Because OrderableDataType is a subclass of DataType, SQLVarchar can play a role in either a DataType/ValueRow or a OrderableDataType/KeyRow, interchangeably. SQLVarchar is mostly the same as SQLChar, so it is implemented as a subclass of SQLChar. Only those methods with different behavior are implemented here.
