public abstract class AbstractDoubleEncapsulatedExpression extends AbstractEncapsulatedExpression
Expression takes care of parsing an expression that encapsulates two expressions
separated by a comma.

acceptChildren(ExpressionVisitor visitor)
Visits the children of this
Expression. |
CollectionExpression |
buildCollectionExpression()
Creates a new
CollectionExpression that will wrap the first and second expressions. |
Expression |
getFirstExpression()
Returns the
Expression that represents the first expression. |
Expression |
getSecondExpression()
Returns the
Expression that represents the second expression. |
boolean |
hasComma()
Determines whether the comma was parsed after the first expression.
|
boolean |
hasEncapsulatedExpression()
Determines whether something was parsed after the left parenthesis.
|
boolean |
hasFirstExpression()
Determines whether the first expression of the query was parsed.
|
boolean |
hasSecondExpression()
Determines whether the second expression of the query was parsed.
|
boolean |
hasSpaceAfterComma()
Determines whether a whitespace was parsed after the comma.

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.
