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

-
getNodeName
public java.lang.String getNodeName()
Format for display, a name for this node.- Specified by:
getNodeName

-
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.
