getEncapsulatedExpressionQueryBNFId
public final java.lang.String getEncapsulatedExpressionQueryBNFId()
Returns the BNF used to parse the encapsulated expression.- Specified by:
getEncapsulatedExpressionQueryBNFIdin classAbstractSingleEncapsulatedExpression- Returns:
- The BNF used to parse the encapsulated expression
-
getQueryBNF
public JPQLQueryBNF getQueryBNF()
Returns the BNF of thisExpression.- Returns:
- The
JPQLQueryBNF, which represents the grammar of thisExpression
-
parse
protected AbstractExpression parse(WordParser wordParser, java.lang.String queryBNFId, boolean tolerant)
Parses the given text by using the specified BNF.- Overrides:
parsein classAbstractExpression- Parameters:
wordParser- The text to parse based on the current position of the cursorqueryBNFId- The unique identifier of theJPQLQueryBNFthat is used to determine how to parse the text at the current cursor position within the JPQL querytolerant- Determines whether the parsing system should be tolerant, meaning if it should try to parse invalid or incomplete queries- Returns:
- The
Expressionrepresenting the given sub-query
