AbstractLiteralExpressionFactory
AbstractLiteralExpressionFactory(java.lang.String id)
- Creates a new
AbstractLiteralExpressionFactory
.
- Parameters:
id
- The unique identifier of this ExpressionFactory
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
