Method Detail

buildExpression

AbstractExpression buildExpression(AbstractExpression parent,
                                   WordParser wordParser,
                                   java.lang.String word,
                                   JPQLQueryBNF queryBNF,

                                   boolean tolerant)

Creates a new Expression.

Specified by:

buildExpression in class ExpressionFactory

Parameters:

parent - The parent expression

wordParser - The text to parse based on the current position of the cursor

word - The current word to parse

queryBNF - The BNF grammar that was used to identifier this factory to be capable to parse a portion of the query

expression - During the parsing, it is possible the first part of an expression was parsed which needs to be used as a sub-expression of the newly created expression

Returns:

A new Expression representing a portion or the totality of the given text

visitor

private AndExpressionFactory.OrExpressionVisitor visitor()
