public ExternalDecimalAsLongField(int offset, int precision, boolean signed, boolean signTrailing, boolean signExternal, boolean blankWhenZero)
offset
- position of this fieldprecision
- total number of digits <= 18.signed
- if the field has a sign somewheresignTrailing
- true if the sign follows the field, false if it precedes itsignExternal
- true if the sign occupies a separate byte, false if it only occupies a high-order nibble
Note: signTrailing and signExternal are ignored if signed is not true.Method Detail |
