Class NumberMetaData

java.lang.Object
  |
  +--xxl.relational.NumberMetaData

public abstract class NumberMetaData
extends java.lang.Object
implements java.sql.ResultSetMetaData

A skeleton implementation of ResultSetMetaData for Numbers.

NumberMetaData represents ResultSetMetaData for a table that has only one column.
There is only one abstract method:


	String getColumnName(int column)

Precision and scale are set to 0.

There is a default implementation for this method:


	NumberMetaData.PROTOTYPE

is a subclass of NumberMetaData where getColumnName always returns "". This class is suitable for using it in AssembledResultSetMetaData to create larger ResultSetMetaData-classes.
