addAtTheEndOfChild
public void addAtTheEndOfChild(SelectClause expression,
CollectionExpression collectionExpression,
int index,
boolean hasComma,
boolean virtualSpace)
- Adds the proposals because the cursor is at the end of the child at the given position.
- Specified by:
addAtTheEndOfChild in interface AbstractContentAssistVisitor.CollectionExpressionHelper<SelectClause>- Overrides:
addAtTheEndOfChild in class AbstractContentAssistVisitor.AbstractSelectClauseCollectionHelper<SelectClause>
- Parameters:
expression - The Expression being visitedcollectionExpression - The CollectionExpression is either the child of the
given Expression or a temporary generated one that usually contains a single itemindex - The position of that child in the collection of childrenhasComma - Indicates whether a comma is present before the child at the given position;
if the index is 0, then this is false by defaultvirtualSpace - Indicates if this method is called because the cursor is at the end of
the child at the specified index but by considering there is a virtual space at the end of
that child
addTheBeginningOfChild
public void addTheBeginningOfChild(SelectClause expression,
CollectionExpression collectionExpression,
int index,

expression - The Expression being visitedcollectionExpression - The CollectionExpression is either the child of the
given Expression or a temporary generated one that usually contains a single item.
This can be null if the position is at the beginningindex - The position of the child that was scannedhasComma - Indicates whether a comma is present before the child at the given position;
if the index is 0, then this is false by default
preExpressionLength
public int preExpressionLength(SelectClause expression)
- Returns the length of anything that can be defined before the first child. An example can
be "
DISTINCT " in "AVG(DISTINCT e.name)".

expression - The Expression being visited
- Returns:
- The length of anything that was parsed before the first child or 0 if nothing was parsed
