toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getChildren

public java.util.Vector getChildren()

RealBasicNoPutResultSetStatistics override.

Overrides:

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.

getRSXplainType

public java.lang.String getRSXplainType()
