public abstract class AbstractDoubleEncapsulatedExpressionStateObject extends AbstractEncapsulatedExpressionStateObject
StateObject represents a JPQL expression that has a JPQL identifier followed by
two an encapsulated expression with parenthesis, the two expression are separated by a comma.

|---|---|
protected void |
addChildren(java.util.List<StateObject> children)
Adds the children of this
StateObject to the given list. |
AbstractDoubleEncapsulatedExpression |
getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
StateObject |
getFirst()
Returns the
StateObject representing the first expression. |
protected abstract java.lang.String |
getFirstQueryBNFId()
Returns the unique identifier of the BNF that will be used to parse a JPQL fragment as the
first encapsulated expression.
|
StateObject |
getSecond()
Returns the
StateObject representing the second expression. |
protected abstract java.lang.String |
getSecondQueryBNFId()
Returns the unique identifier of the BNF that will be used to parse a JPQL fragment as the
second encapsulated expression.
|
boolean |
hasFirst()
Determines whether the
StateObject representing the first encapsulated expression is
present or not. |
boolean |
hasSecond()
Determines whether the
StateObject representing the second encapsulated expression is
present or not. |
boolean |
isEquivalent(StateObject stateObject)
Determines whether the given
StateObject is equivalent to this one, i.e. the
information of both StateObject is the same. |
void |
parseFirst(java.lang.String jpqlFragment)
Parses the given JPQL fragment, which will represent the first encapsulated expression.
|
void |
parseSecond(java.lang.String jpqlFragment)
Parses the given JPQL fragment, which will represent the second encapsulated expression.
|
void |
setFirst(StateObject firstStateObject)
Sets the given
StateObject to represent the first encapsulated expression. |
void |
setSecond(StateObject secondStateObject)
Sets the given
StateObject to represent the second encapsulated expression. |
protected void |
toTextEncapsulatedExpression(java.lang.Appendable writer)
Prints out a string representation of this encapsulated information, which should not be used
to define a
true string representation of a JPQL query but should be used for
debugging purposes. |
