Constructor Detail
-
EntityTypeLiteral
public EntityTypeLiteral(AbstractExpression parent, java.lang.String entityTypeName)
Creates a newEntityTypeLiteral
.- Parameters:
parent
- The parent of this expressionentityTypeName
- The name of the entity
-
-
Method Detail
-
accept
public void accept(ExpressionVisitor visitor)
Visits thisExpression
by the givenvisitor
.- Parameters:
visitor
- TheExpressionVisitor
to visit this object
-
acceptChildren
public void acceptChildren(ExpressionVisitor visitor)
Visits the children of thisExpression
. This method can be used to optimize traversing the children since a new list is not created every timeExpression.children()
is called.This does not traverse the
Expression
sub-hierarchy, use a subclass ofAbstractTraverseChildrenVisitor
in order to traverse the entire sub-hierarchy.- Parameters:
visitor
- Thevisitor
to visit the children of this object.
-
getEntityTypeName
public java.lang.String getEntityTypeName()
Returns the name of the entity type.- Returns:
- The name of the entity that was parsed
-
getQueryBNF
public JPQLQueryBNF getQueryBNF()
Returns the BNF of thisExpression
.- Returns:
- The
JPQLQueryBNF
, which represents the grammar of thisExpression
-
toParsedText
public java.lang.String toParsedText()
Returns a string representation of thisExpression
and its children. The expression should contain whitespace even if the beautified version would not have any. For instance, "SELECT e " should be returned whereExpression.toParsedText()
would return "SELECT e".- Specified by:
toParsedText
in interfaceExpression
- Overrides:
toParsedText
in classAbstractExpression
- Returns:
- The string representation of this
Expression
