What is the significance of new int[]{0} in appendWhere of

querySpec.appendWhere(
new SearchCondition(EPMDocument.class, "master>number", SearchCondition.EQUAL, number, true),
new int[] { 0 });

See snippet below. When you have multiple classes in the query (similar to From declaration), it needs to index the classes. That same index is used to tie into where clauses. 

QuerySpec spec=new QuerySpec();
int wtPart=spec.addClassList(WTPartMaster.class,true);
SearchCondition sc=new SearchCondition(WTPartMaster.class,WTPartMaster.NUMBER,SearchCondition.EQUAL,number.toUpperCase());
spec.appendWhere(sc, new int[] {wtPart});
