Examples with GroupImpl com.querydsl.core.group.GroupImpl used on opensource projects

Example 1 with GroupImpl

use of com.querydsl.core.group.GroupImpl in project querydsl by querydsl.

the class GroupByMultimap method transform.

@Override
public R transform(FetchableQuery<?, ?> query) {
    Multimap<K, Group> groups = LinkedHashMultimap.create();
    // create groups
    FactoryExpression<Tuple> expr = FactoryExpressionUtils.wrap(Projections.tuple(expressions));
    boolean hasGroups = false;
    for (Expression<?> e : expr.getArgs()) {
        hasGroups |= e instanceof GroupExpression;
    }
    if (hasGroups) {
        expr = withoutGroupExpressions(expr);
    }
    CloseableIterator<Tuple> iter = query.select(expr).iterate();
    try {
        while (iter.hasNext()) {
            // This type is mandated by the key type
            @SuppressWarnings("unchecked") K[] row = (K[]) iter.next().toArray();
            K groupId = row[0];
            GroupImpl group = new GroupImpl(groupExpressions, maps);
            groups.put(groupId, group);
            group.add(row);
        }
    } finally {
        iter.close();
    }
    // transform groups
    return transform(groups);
}

Example 2 with GroupImpl

use of com.querydsl.core.group.GroupImpl in project querydsl by querydsl.

the class GroupByTable method transform.

@Override
public RES transform(FetchableQuery<?, ?> query) {
    // TODO Table<Object, Object, Group> after support for it in https://github.com/querydsl/querydsl/issues/2644
    Table<R, Object, Group> groups = HashBasedTable.create();
    // create groups
    FactoryExpression<Tuple> expr = FactoryExpressionUtils.wrap(Projections.tuple(expressions));
    boolean hasGroups = false;
    for (Expression<?> e : expr.getArgs()) {
        hasGroups |= e instanceof GroupExpression;
    }
    if (hasGroups) {
        expr = withoutGroupExpressions(expr);
    }
    CloseableIterator<Tuple> iter = query.select(expr).iterate();
    try {
        while (iter.hasNext()) {
            // This type is mandated by the key type
            @SuppressWarnings("unchecked") Object[] row = iter.next().toArray();
            R groupId = (R) row[0];
            Object rowId = row[1];
            GroupImpl group = (GroupImpl) groups.get(groupId, rowId);
            if (group == null) {
                group = new GroupImpl(groupExpressions, maps);
                groups.put(groupId, rowId, group);
            }
            group.add(row);
        }
    } finally {
        iter.close();
    }
    // transform groups
    return transform(groups);
