| Modifier and Type | Method and Description |
|---|---|
protected void |
addChildren(java.util.List<StateObject> children)
Adds the children of this
StateObject to the given list. |
CompoundExpression |
getExpression()
Returns the actual parsed object if this
StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
abstract java.lang.String |
getIdentifier()
Returns the identifier joining the two
StateObjects. |
StateObject |
getLeft()
Returns the
StateObject that represents the left expression. |
protected abstract java.lang.String |
getLeftQueryBNFId()
Returns the unique identifier of the BNF that will be used to parse a JPQL fragment as the
left side of the expression.
|
StateObject |
getRight()
Returns the
StateObject that represents the right expression. |
protected abstract java.lang.String |
getRightQueryBNFId()
Returns the unique identifier of the BNF that will be used to parse a JPQL fragment as the
right side of the expression.
|
boolean |
hasLeft()
Determines whether there is a
StateObject that represents the left expression. |
boolean |
hasRight()
Determines whether there is a
StateObject that represents the right expression. |
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 |
parseLeft(java.lang.String jpqlFragment)
Parses the given JPQL fragment and update the left side of the compound expression.
|
void |
parseRight(java.lang.String jpqlFragment)
Parses the given JPQL fragment and update the right side of the compound expression.
|
void |
setLeft(StateObject leftStateObject)
Sets the left
StateObject to become the given object. |
void |
setRight(StateObject rightStateObject)
Sets the right
StateObject to become the given object. |
protected void |
toTextInternal(java.lang.Appendable writer)
Prints out a string representation of this
StateObject, which should not be used to
define a true string representation of a JPQL query but should be used for
debugging purposes. |
