void |
appendNextClauseProposals(AbstractSelectStatement expression,
AbstractSelectClause clause,
int position,
boolean complete)
The position of the cursor is at the end of the given clause, requests to add the clauses' identifiers that can be added as proposals. |

Returns the clause's expression. |
AbstractContentAssistVisitor.SelectStatementHelper<AbstractSelectStatement,Expression> |
getPreviousHelper()
Returns the AbstractContentAssistVisitor.AbstractFromClauseSelectStatementHelper that will scan the previous clause, which is
based on the grammar and not on the actual existence of the clause in the parsed tree. |
boolean |
hasClause(AbstractSelectStatement expression)
Determines whether the clause exists in the parsed tree. |
boolean |
hasClauseExpression(AbstractSelectClause clause)
Determines whether the clause's expression exists in the parsed tree. |
boolean |
hasSpaceAfterClause(AbstractSelectStatement expression)
Determines whether there is a space (owned by the SELECT statement) after the clause being scanned by this helper. |
boolean |
hasSpaceBeforeClause(AbstractSelectStatement expression)
Determines whether there is a space (owned by the SELECT statement) before the clause being scanned by this helper. |
