Field Summary
static java.lang.String ID
          The unique identifier of this BNF rule.
 
Constructor Summary
ArithmeticTermBNF()
          Creates a new ArithmeticTermBNF.
 
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.
 boolean handleAggregate()
          Determines whether the Expression handles a collection of sub-expressions that are aggregated by logical or arithmetic operators.
(package private)  void initialize()
          Initializes this BNF rule by registering child BNF rules and expression factories.

Constructor Detail

ArithmeticTermBNF

ArithmeticTermBNF()
Creates a new ArithmeticTermBNF.
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

handleAggregate

public boolean handleAggregate()
Determines whether the Expression handles a collection of sub-expressions that are aggregated by logical or arithmetic operators.
Overrides:
handleAggregate in class JPQLQueryBNF
Returns:
true if the sub-expression to parse might have several logical and/or arithmetic expressions; false otherwise

initialize

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