void |
accept(ExpressionVisitor visitor)
Visits this
Expression by the given visitor . |
void |
acceptChildren(ExpressionVisitor visitor)
Visits the children of this
Expression . |
Expression |
getAbstractSchemaName()
Returns the
Expression that represents the abstract schema name. |
Expression |
getIdentificationVariable()
Returns the
Expression that represents the identification variable. |
JPQLQueryBNF |
getQueryBNF()
Returns the BNF of this
Expression . |
boolean |
hasAbstractSchemaName()
Determines whether the abstract schema name was parsed.
|
boolean |
hasAs()
Determines whether the identifier AS was parsed.
|
boolean |
hasIdentificationVariable()
Determines whether the identification variable was parsed.
|
boolean |
hasSpaceAfterAbstractSchemaName()
Determines whether a whitespace was parsed after the abstract schema name.
|
boolean |
hasSpaceAfterAs()
Determines whether a whitespace was parsed after AS.
|
boolean |
hasVirtualIdentificationVariable()
Determines whether this identification variable is virtual, meaning it's not part of the
query but is required for proper navigability.
|
void |
setVirtualIdentificationVariable(java.lang.String variableName,
java.lang.String path)
Sets a virtual identification variable because the abstract schema name was parsed without
one.

Expression
. This method can be used to optimize traversing
the children since a new list is not created every time Expression.children()
or Expression.getChildren()
is called.
This does not traverse the Expression
sub-hierarchy, use an subclass of
AbstractTraverseChildrenVisitor
in order to traverse the entire sub-hierarchy.
