    • Method Detail

      • initWithProperties

        public void initWithProperties​(Map<String,​?> properties)
      • getMetaData

        public QueryMetadata getMetaData​(EntityResolver resolver)
        Description copied from interface: Query
        Returns query runtime parameters. The method is called at various stages of the execution by Cayenne access stack to retrieve query parameters. EntityResolver instance is passed to this method, meaning that the query doesn't need to store direct references to Cayenne mapping objects and can resolve them at runtime.
      • isFetchingDataRows

        public boolean isFetchingDataRows()
      • setFetchingDataRows

        public void setFetchingDataRows​(boolean flag)
      • getBaseMetaData

        protected org.apache.cayenne.query.BaseQueryMetadata getBaseMetaData()
        Specified by:
        getBaseMetaData in class CacheableQuery
      • route

        public void route​(QueryRouter router,
                          EntityResolver resolver,
                          Query substitutedQuery)
        Description copied from interface: Query
        A callback method invoked by Cayenne during the routing phase of the query execution. Mapping of DataNodes is provided by QueryRouter. Query should use a QueryRouter.route(QueryEngine, Query, Query) callback method to route itself. Query can create one or more substitute queries or even provide its own QueryEngine to execute itself.
      • createSQLAction

        public SQLAction createSQLAction​(SQLActionVisitor visitor)
        Description copied from interface: Query
        A callback method invoked by Cayenne during the final execution phase of the query run. A concrete query implementation is given a chance to decide how it should be handled. Implementors can pick an appropriate method of the SQLActionVisitor to handle itself, create a custom SQLAction of its own, or substitute itself with another query that should be used for SQLAction construction.
      • getEjbqlStatement

        public String getEjbqlStatement()
        Returns an unparsed EJB QL statement used to initialize this query.
      • getNamedParameters

        public Map<String,​Object> getNamedParameters()
        Returns unmodifiable map of combined named and positional parameters. Positional parameter keys are Integers, while named parameter keys are strings.
      • getPositionalParameters

        public Map<Integer,​Object> getPositionalParameters()
      • setParameter

        public void setParameter​(String name,
                                 Object object)
        Sets a named query parameter value.
      • setParameter

        public void setParameter​(int position,
                                 Object object)
        Sets a positional query parameter value. Note that parameter indexes are starting from 1.
      • getFetchLimit

        public int getFetchLimit()
        Returns the fetchLimit property indicating the maximum number of rows this query would return.
      • setFetchLimit

        public void setFetchLimit​(int fetchLimit)
        Sets the fetchLimit property indicating the maximum number of rows this query would return.
      • getFetchOffset

        public int getFetchOffset()
      • setFetchOffset

        public void setFetchOffset​(int fetchOffset)
      • setEjbqlStatement

        public void setEjbqlStatement​(String text)
      • getPageSize

        public int getPageSize()
      • setPageSize

        public void setPageSize​(int pageSize)
      • setStatementFetchSize

        public void setStatementFetchSize​(int size)
        Sets statement's fetch size (0 for no default size)
        Since:
        3.0
      • getStatementFetchSize

        public int getStatementFetchSize()
        Returns:
        statement's fetch size
        Since:
        3.0
