Example 2 with ComparableSet

the class PropertiesTable method createSecondaryKeys.

public static ByteIterable[] createSecondaryKeys(@NotNull final PropertyTypes propertyTypes, @NotNull final ByteIterable value, @NotNull final ComparableValueType type) {
    final int valueTypeId = type.getTypeId();
    if (valueTypeId == ComparableValueType.STRING_VALUE_TYPE) {
        final PropertyValue propValue = propertyTypes.entryToPropertyValue(value);
        return new ByteIterable[] { new PropertyValue(type, ((String) propValue.getData()).toLowerCase()).dataToEntry() };
    }
    if (valueTypeId == ComparableValueType.COMPARABLE_SET_VALUE_TYPE) {
        final PropertyValue propValue = propertyTypes.entryToPropertyValue(value);
        final ComparableSet data = (ComparableSet) propValue.getData();
        final Class itemClass = data.getItemClass();
        final ComparableBinding itemBinding = propertyTypes.getPropertyType(itemClass).getBinding();
        final ByteIterable[] result = new ByteIterable[data.size()];
        // noinspection unchecked
        data.forEach((item, index) -> result[index] = itemBinding.objectToEntry(PropertyTypes.toLowerCase(item)));
        return result;
    }
    // skip property type
    return new ByteIterable[] { value.subIterable(1, value.getLength() - 1) };
}

Example 3 with ComparableSet

    for (int i = 0; i < 1000; ++i) {
        Assert.assertEquals(setSize, randomSet.size());

        randomSet.forEach((item, index) -> Assert.assertEquals(issue, txn.find("Issue", "randomSet", item).getFirst()));
        Assert.assertTrue(randomSet.removeItem(randomSet.iterator().next()));
        while (true) {
