com.google.api.services.datastore.DatastoreV1.Filter

Subsets of Unicode characters identified by their general category. The categories are identified by constants defined in the {@link Character} class, like{@link Character#LOWERCASE_LETTER LOWERCASE_LETTER}, {@link Character#UPPERCASE_LETTER UPPERCASE_LETTER}, {@link Character#DECIMAL_DIGIT_NUMBER DECIMAL_DIGIT_NUMBER} and{@link Character#SPACE_SEPARATOR SPACE_SEPARATOR}.

An instance of this class can be obtained from an enumeration of character types using the {@link #forTypes(byte[])} method, or using one of the constants predefinedin this class. Then, Unicode characters can be tested for inclusion in the subset by calling the {@link #contains(int)} method.
