Method Detail

serialize

@Nonnull
public final SerializedQuery<QueryT> serialize(@Nonnull
                                                        QueryT query)
                                                 throws QuerySerializationException

Serialize a query. Exceptions are wrapped and converted to QuerySerializationException.

Specified by:

serialize in interface QuerySerializer<QueryT extends Query<QueryT,QueryResultT>,QueryResultT extends QueryResult<QueryT,QueryResultT>>

Throws:

QuerySerializationException - If there is an issue while serializing the query.

deserialize

@Nonnull
public final QueryResultT deserialize(@Nonnull
                                               SerializedQueryResult<QueryT> queryResult)
                                        throws QuerySerializationException

Deserialize a query result. Exceptions are wrapped and converted to QuerySerializationException.

Specified by:

deserialize in interface QuerySerializer<QueryT extends Query<QueryT,QueryResultT>,QueryResultT extends QueryResult<QueryT,QueryResultT>>

Throws:

QuerySerializationException - If there is an issue while deserializing the query.

serializeQuery

@Nonnull
protected abstract SerializedQuery<QueryT> serializeQuery(@Nonnull
                                                                   QueryT query)
                                                            throws Exception

Serialize a query. Allows to generically throw an exception which is converted to QuerySerializationException by serialize(Query).

Throws:

Exception - If there is an issue while serializing the query.

deserializeQueryResult

@Nonnull
protected abstract QueryResultT deserializeQueryResult(@Nonnull
                                                                SerializedQueryResult<QueryT> serializedQueryResult)
                                                         throws Exception

Deserialize a query result. Allows to generically throw an exception which is converted to QuerySerializationException by deserialize(SerializedQueryResult).

Throws:

Exception - If there is an issue while serializing the query.
