protected int[]	fieldNumbers
protected FieldIDMapper	fim

Constructor Summary

RecordSpec(int len)
Constructor that creates an identity mapping of the specified length.

RecordSpec(int[] specs)
Constructor that takes an array of ints

Method Summary

FieldIDMapper	getFieldIDMapper() Returns the FieldIDMapper equivalent to this RecordSpec
int	getFieldNumber(int index) Returns the FieldSpec at the index position.
int[]	getFieldNumbers() get the field number array
int	getIndexedFieldNumber(int index) Deprecated. Use getFieldNumber( int )
