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
