toString

public final StringBuilder toString(StringBuilder sb)

Append a string representation of the object to the given StringBuilder. In general, the toString method for query objects appends a string that textually represents this object. The result should be a query string that complies to EJB QL specification as long as the query object represents a syntay element of it. It is required that all subclasses override this method. The toString method defined at class Object is overwritten and calls this method.

Parameters:

sb - StringBuilder to append the string representation of this object to.

Returns:

Same instance of StringBuilder given as parameter.
