getEscapeChar
public char getEscapeChar()
- This method will return an escape character for the like
 clause.  The escape character will eventually end up in the
 query as - ...(t0.foo LIKE ? {escape '|'}) where the
 pipe symbol is the escape character.
 - Note that having no escape character is represented as 
 the character 0. -

setEscapeChar
public void setEscapeChar(char value)
- This method allows the setting of the escape character.
 The escape character can be used in a LIKE clause.  The
 character 0 signifies no escape character.  The escape
 characyer '?' is disallowed. -

jjtAddChild
public void jjtAddChild(Node n,
                        int i)
- Description copied from interface: Node
- This method tells the node to add its argument to the node's
      list of children.
