My understanding was that he wanted to have an Id for medical records
since nothing else would use that sequence name it would be sequencel
staggerMax is set to 1 by default
public String getNextSeqId(String seqName) {
return this.getNextSeqId(seqName, 1);
}
now if you call
public String getNextSeqId(String seqName, long staggerMax) {
Long nextSeqLong = this.getNextSeqIdLong(seqName, staggerMax);
if (nextSeqLong == null) {
// NOTE: the getNextSeqIdLong method SHOULD throw a runtime
exception when no sequence value is found, which means we should never
see it get here
throw new IllegalArgumentException("Could not get next
sequenced ID for sequence name: " + seqName);
}
if
(UtilValidate.isNotEmpty(this.getDelegatorInfo().sequencedIdPrefix)) {
return this.getDelegatorInfo().sequencedIdPrefix +
nextSeqLong.toString();
} else {
return nextSeqLong.toString();
}
}
then it would be staggered. this is not defualt
or have I missed something.
