Class ContentAssistVisitor.AppendableExpressionVisitor

java.lang.Object

All Implemented Interfaces:

ExpressionVisitor

Enclosing class:

ContentAssistVisitor

private class ContentAssistVisitor.AppendableExpressionVisitor

extends AbstractTraverseChildrenVisitor

This visitor scans the visited Expression and determines if a JPQL identifier can be added when the position is at the end of a clause and the ending of the clause can be seen as the beginning of an identifier.

For instance, in "SELECT e, AVG(e.age) F", F is parsed as a result variable but can also be seen as the first letter for FROM.
