Examples with ColumnDescriptor org.apache.ignite.internal.storage.index.SortedIndexDescriptor.ColumnDescriptor used on opensource projects

Example 1 with ColumnDescriptor

use of org.apache.ignite.internal.storage.index.SortedIndexDescriptor.ColumnDescriptor in project ignite-3 by apache.

the class PrefixComparator method compare.

/**
 * Compares a given row with the configured prefix.
 *
 * @param binaryRow Row to compare.
 * @return the value {@code 0} if the given row starts with the configured prefix;
 *         a value less than {@code 0} if the row's prefix is smaller than the prefix; and
 *         a value greater than {@code 0} if the row's prefix is larger than the prefix.

int compare(BinaryRow binaryRow) {
    var row = new Row(descriptor.asSchemaDescriptor(), binaryRow);
    for (int i = 0; i < prefix.length; ++i) {
        ColumnDescriptor columnDescriptor = descriptor.indexRowColumns().get(i);
        int compare = compare(columnDescriptor.column(), row, prefix[i]);
        if (compare != 0) {
            return columnDescriptor.asc() ? compare : -compare;
        }
    }
    return 0;
}

Example 2 with ColumnDescriptor

use of org.apache.ignite.internal.storage.index.SortedIndexDescriptor.ColumnDescriptor in project ignite-3 by apache.

the class IndexRowWrapper method randomRow.

/**
 * Creates an Entry with a random key that satisfies the given schema and a random value.
 */
static IndexRowWrapper randomRow(SortedIndexStorage indexStorage) {
    var random = new Random();
    Object[] columns = indexStorage.indexDescriptor().indexRowColumns().stream().map(ColumnDescriptor::column).map(column -> generateRandomValue(random, column.type())).toArray();
    var primaryKey = new ByteArraySearchRow(randomBytes(random, 25));
    IndexRow row = indexStorage.indexRowFactory().createIndexRow(columns, primaryKey);
    return new IndexRowWrapper(indexStorage, row, columns);
