- All Implemented Interfaces:
- java.lang.Comparable<ExpressionFactory>
public final class JoinCollectionValuedPathExpressionFactory
- extends AbstractCollectionValuedPathExpressionFactory
This factory is used by EclipseLink 2.4 to add support for parsing an abstract schema name when
the expression is not a join association path expression.

JoinCollectionValuedPathExpressionFactory
public JoinCollectionValuedPathExpressionFactory()
- Creates a new
JoinCollectionValuedPathExpressionFactory
.
buildFallbackExpression
protected AbstractExpression buildFallbackExpression(AbstractExpression parent,
WordParser wordParser,
java.lang.String word,
JPQLQueryBNF queryBNF,
AbstractExpression expression,
boolean tolerant)
- Creates a new
Expression
when the word is not a path expression, i.e. does have any
dot.
- Specified by:
buildFallbackExpression
in class AbstractCollectionValuedPathExpressionFactory
- Parameters:
parent
- The parent expressionwordParser
- The text to parse based on the current position of the cursorword
- The current word to parsequeryBNF
- The BNF grammar that was used to identifier this factory to be capable to
parse a portion of the queryexpression
- 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
