public class AbsExpressionStateObject extends AbstractSingleEncapsulatedExpressionStateObject
ABS function removes the minus sign from a specified argument and returns
the absolute value, which is always a positive number or zero.
This is one of the JPQL arithmetic functions. The ABS function takes a
numeric argument and returns a number (integer, float, or double) of the same type as the
argument to the function.

| Modifier and Type | Method and Description |
|---|---|
void |
accept(StateObjectVisitor visitor)
Visits this
StateObject by the given visitor. |
AbsExpression |
getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
String |
getIdentifier()
Returns the JPQL identifier of the expression represented by this
AbstractSingleEncapsulatedExpressionStateObject. |
protected String |
getQueryBNFId()
Returns the unique identifier of the
JPQLQueryBNF that will determine how to parse the encapsulated expression. |
void |
setExpression(AbsExpression expression)
Keeps a reference of the
parsed object object, which should only be
done when this object is instantiated during the conversion of a parsed JPQL query into
StateObjects. |
void |
setStateObject(StateObject stateObject)
Sets the given
StateObject to represent the new encapsulated expression. |
