public class SqrtExpressionStateObject extends AbstractSingleEncapsulatedExpressionStateObject
SQRT function takes a numeric argument and returns a Double.

|---|
SqrtExpressionStateObject(StateObject parent)
Creates a new
SqrtExpressionStateObject. |
SqrtExpressionStateObject(StateObject parent,
StateObject stateObject)
Creates a new
SqrtExpressionStateObject. |
SqrtExpressionStateObject(StateObject parent,
java.lang.String jpqlFragment)
Creates a new
SqrtExpressionStateObject. |
| Modifier and Type | Method and Description |
|---|---|
void |
accept(StateObjectVisitor visitor)
Visits this
StateObject by the given visitor. |
SqrtExpression |
getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
java.lang.String |
getIdentifier()
Returns the JPQL identifier of the expression represented by this
AbstractSingleEncapsulatedExpressionStateObject. |
protected java.lang.String |
getQueryBNFId()
Returns the unique identifier of the
JPQLQueryBNF that will determine how to parse the encapsulated expression. |
void |
setExpression(SqrtExpression 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. |
