Method Details
-
getString
Gets the string expression of SUBSTRING function.- Returns:
- The string expression of SUBSTRING function.
-
setString
Sets the string expression of SUBSTRING function.- Parameters:
string
- The new string expression of SUBSTRING function.
-
getIndex
Gets the start expression of SUBSTRING function.- Returns:
- The start expression of SUBSTRING function.
-
setIndex
Sets the start expression of SUBSTRING function.- Parameters:
index
- The new start expression of SUBSTRING function.
-
getLength
Gets the length expression of SUBSTRING function.- Returns:
- The length expression of SUBSTRING function.
-
setLength
Sets the length expression of SUBSTRING function.- Parameters:
length
- The new length expression of SUBSTRING function.
-
toString
Append a string representation of the object to the givenStringBuilder
. 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.
