Example 6 with NestedObjectExpression

use of io.crate.operation.reference.NestedObjectExpression in project crate by crate.

the class SysObjectArrayReference method getChildImplementation.

@Override
public ReferenceImplementation<Object[]> getChildImplementation(String name) {
    List<NestedObjectExpression> childImplementations = getChildImplementations();
    final Object[] values = new Object[childImplementations.size()];
    int i = 0;
    for (NestedObjectExpression sysObjectReference : childImplementations) {
        ReferenceImplementation<?> child = sysObjectReference.getChildImplementation(name);
        if (child != null) {
            Object value = child.value();
            values[i++] = value;
        } else {
            values[i++] = null;
        }
    }
    return () -> values;
}

Example 7 with NestedObjectExpression

use of io.crate.operation.reference.NestedObjectExpression in project crate by crate.

the class SysObjectArrayReference method value.

@Override
public Object[] value() {
    List<NestedObjectExpression> childImplementations = getChildImplementations();
    Object[] values = new Object[childImplementations.size()];
    int i = 0;
    for (NestedObjectExpression expression : childImplementations) {
        Map<String, Object> map = Maps.transformValues(expression.getChildImplementations(), new Function<ReferenceImplementation, Object>() {

            @Nullable
            @Override
            public Object apply(@Nullable ReferenceImplementation input) {
                Object value = input.value();
                if (value != null && value instanceof BytesRef) {
                    return ((BytesRef) value).utf8ToString();
                } else {
                    return value;
                }
            }
        });
