Interface for metadata fields which holds an ordered value (such as a date) and which can
be used for range queries. Implementations of this interface (such as the static values in
SearchableField)
can be used to create inequality filters for file queries.
For example, the following code will find all files that were modified in the last hour with the MIME type "text/plain":
Date oneHourAgo = new Date(System.currentTimeMillis() - (60 * 60 * 1000));
Filter dateFilter = Filters.greaterThan(SearchableField.MODIFIED_DATE, oneHourAgo);
Filter mimeTypeFilter = Filters.eq(SearchableField.MIME_TYPE, "text/plain");
Query query = new Query.Builder().addFilters(dateFilter, mimeTypeFilter).build();
for (Metadata metadata : Drive.DriveApi.query(apiClient, query).await().getMetadataBuffer()) {
System.out.println(metadata.getTitle());
}
Note that you must pass an
SearchableOrderedMetadataField to the
Filters#greaterThan,
Filters#lessThan,
Filters#lessThanEquals, or
Filters#greaterThanEquals methods; a plain SearchableMetadataField
cannot be used as part of an inequality query. However, every
SearchableOrderedMetadataField is also a SearchableMetadataField,
so you can use a
SearchableOrderedMetadataField with
Filters#eq (for example, if you want to find a file that was modified at an exact
time).
