property<T> static method

FilterBuilder<T> property<T>(String property)

Order elements by a certain child value before filtering them.

When using orderBy with the name of a child key, data that contains the specified child key will be ordered as follows:

1. Children with a null value for the specified child key come first.
2. Children with a value of false for the specified child key come next. If multiple children have a value of false, they are sorted lexicographically by key.
3. Children with a value of true for the specified child key come next. If multiple children have a value of true, they are sorted lexicographically by key.
4. Children with a numeric value come next, sorted in ascending order. If multiple children have the same numerical value for the specified child node, they are sorted by key.
5. Strings come after numbers, and are sorted lexicographically in ascending order. If multiple children have the same value for the specified child node, they are ordered lexicographically by key.
6. Objects come last, and sorted lexicographically by key in ascending order.

The filtered results are returned unordered. If the order of your data is important you should sort the results in your application after they are returned from Firebase.
