  • Method Details

    • getStatementExecutionPlanText

      public String getStatementExecutionPlanText(int depth)
      Return the statement execution plan as a String.
      Parameters:
      depth - Indentation level.
      Returns:
      String The statement executio plan as a String.
    • getScanStatisticsText

      public String getScanStatisticsText(String tableName, int depth)
      Return information on the scan nodes from the statement execution plan as a String.
      Parameters:
      tableName - if not NULL then print information for this table only
      depth - Indentation level.
      Returns:
      String The information on the scan nodes from the statement execution plan as a String.
    • toString

      public String toString()
      Overrides:
      toString in class Object
    • getNodeOn

      public String getNodeOn()
      If this node is on a database item (like a table or an index), then provide a string that describes the on item.
      Overrides:
      getNodeOn in class RealBasicNoPutResultSetStatistics
    • getNodeName

      public String getNodeName()
      Format for display, a name for this node.
      Specified by:
      getNodeName in class RealBasicNoPutResultSetStatistics
    • accept

      public void accept(XPLAINVisitor visitor)
      Description copied from interface: XPLAINable
      This method gets called to let a visitor visit this XPLAINable object. The general contract is to implement pre-order, depth-first traversal to produce a predictable traversal behaviour.

    • getRSXplainDetails

      public String getRSXplainDetails()
      Specified by:
      getRSXplainDetails in interface XPLAINable
      Overrides:
      getRSXplainDetails in class RealBasicNoPutResultSetStatistics
    • getScanPropsDescriptor

      public Object getScanPropsDescriptor(Object scanPropsID)
      Specified by:
      getScanPropsDescriptor in interface XPLAINable
      Overrides:
      getScanPropsDescriptor in class RealBasicNoPutResultSetStatistics
