Field Summary
static java.lang.String ID
          The unique identifier of this BNF rule.

 

Constructor Summary

          Creates a new InputParameterBNF.

 

Method Summary
(package private)  java.lang.String getFallbackBNFId()
          When parsing the query and no JPQLQueryBNFs can help to parse the query, then it will fall back on this one.
(package private)  java.lang.String getFallbackExpressionFactoryId()
          Returns the unique identifier of the ExpressionFactory to use when the fall back BNF ID is not null.
(package private)  void initialize()
          Initializes this BNF rule by registering child BNF rules and expression factories.

Method Detail

getFallbackBNFId

java.lang.String getFallbackBNFId()
When parsing the query and no JPQLQueryBNFs can help to parse the query, then it will fall back on this one.
Overrides:
getFallbackBNFId in class JPQLQueryBNF
Returns:
The unique identifier of the JPQLQueryBNF to use in the last resort

getFallbackExpressionFactoryId

java.lang.String getFallbackExpressionFactoryId()
Returns the unique identifier of the ExpressionFactory to use when the fall back BNF ID is not null. This will be used to parse a portion of the query when the registered expression factories cannot parse it.

Note: This method is only called if JPQLQueryBNF.getFallbackBNFId() does not return null.

Overrides:
getFallbackExpressionFactoryId in class JPQLQueryBNF
Returns:
The unique identifier of the ExpressionFactory

initialize

void initialize()
Initializes this BNF rule by registering child BNF rules and expression factories.
Overrides:
initialize in class JPQLQueryBNF
