public class SimplePmdDataFactory extends org.pentaho.reporting.engine.classic.core.AbstractDataFactory
Performs MQL queries. A MQL-query usually contains all information needed to connect to the database. However the platform also allows to override the connection-information and to provide an own connection instead.

We mirror that case by allowing to provide a connection provider. If no connection provider is given, we use whatever connection information is stored in the MQL data itself.

    • isQueryExecutable

      public boolean isQueryExecutable(String query, org.pentaho.reporting.engine.classic.core.DataRow parameters)
      Checks whether the query would be executable by this datafactory. This performs a rough check, not a full query.
      Parameters:
      query - the query.
      parameters - the parameters.
      Returns:
      true, if the query would be executable, false if the query is not recognized.

    • close

      public void close()
      Closes the data factory and frees all resources held by this instance.

    • queryData

      public TableModel queryData(String queryName, org.pentaho.reporting.engine.classic.core.DataRow parameters) throws org.pentaho.reporting.engine.classic.core.ReportDataFactoryException
      Queries a datasource. The string 'query' defines the name of the query. The Parameterset given here may contain more data than actually needed for the query.

      The parameter-dataset may change between two calls, do not assume anything, and do not hold references to the parameter-dataset or the position of the columns in the dataset.

      Parameters:
      queryName - the query name
      parameters - the parameters for the query
      Returns:
      the result of the query as table model.
      Throws:
      org.pentaho.reporting.engine.classic.core.ReportDataFactoryException - if an error occured while performing the query.

    • derive

      public org.pentaho.reporting.engine.classic.core.DataFactory derive()
      Returns a copy of the data factory that is not affected by its anchestor and holds no connection to the anchestor anymore. A data-factory will be derived at the beginning of the report processing.
      Specified by:
      derive in interface org.pentaho.reporting.engine.classic.core.DataFactory
      Overrides:
      derive in class org.pentaho.reporting.engine.classic.core.AbstractDataFactory
      Returns:
      a copy of the data factory.
