Examples with ComparableValueType jetbrains.exodus.bindings.ComparableValueType used on opensource projects

Example 1 with ComparableValueType

use of jetbrains.exodus.bindings.ComparableValueType in project xodus by JetBrains.

the class PropertyTypes method entryToPropertyValue.

public PropertyValue entryToPropertyValue(@NotNull final ByteIterable entry) {
    final ByteIterableBase it = (ByteIterableBase) entry;
    final byte[] bytes = it.getBytesUnsafe();
    final ComparableValueType type = getPropertyType((byte) (bytes[0] ^ 0x80));
    final Comparable data = type.getBinding().readObject(new ByteArrayInputStream(bytes, 1, it.getLength() - 1));
    return new PropertyValue(type, data);
}

Example 2 with ComparableValueType

the class PropertyTypes method clear.

public void clear() {
    typesById.clear();
    typesByClass.clear();
    for (final ComparableValueType predefinedType : ComparableValueType.PREDEFINED_COMPARABLE_VALUE_TYPES) {
        typesById.put(predefinedType.getTypeId(), predefinedType);
        typesByClass.put(predefinedType.getClazz(), predefinedType);
    }
    final ComparableValueType comparableSetType = typesByClass.get(ComparableSet.class);
    final ComparableSetBinding newBinding = new ComparableSetBinding() {

        @Override
        protected ComparableValueType getType(@NotNull Class<? extends Comparable> itemClass) {
            final ComparableValueType result = super.getType(itemClass);
            return result == null ? typesByClass.get(itemClass) : result;
        }

        @Override
        protected ComparableBinding getBinding(int valueTypeId) {
            final ComparableBinding result = super.getBinding(valueTypeId);
            return result == null ? typesById.get(valueTypeId).getBinding() : result;
        }
    };
    final int typeId = comparableSetType.getTypeId();
