Constructor Detail

AbstractLiteralExpressionFactory

AbstractLiteralExpressionFactory(java.lang.String id)

Creates a new AbstractLiteralExpressionFactory.

Parameters:

id - The unique identifier of this ExpressionFactory

Method Detail

buildExpression

abstract AbstractExpression buildExpression(AbstractExpression parent,
                                            WordParser wordParser,
                                            java.lang.String word,
                                            AbstractExpression expression,
                                            boolean tolerant)

Creates the actual AbstractExpression this factory manages.

Parameters:

parent - The parent expression

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

word - The current word to parse

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 AbstractExpression representing the given word

buildExpression

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