Method Detail

initialize

void initialize()

Initializes this BNF rule by registering child BNF rules and expression factories.

Overrides:

initialize in class JPQLQueryBNF

isCompound

public boolean isCompound()

Determines whether this BNF has child BNFs registered only to properly parse a query or if the child BNFs are part of the BNF. An example if a compound BNF is BetweenExpressionBNF, it registers a series of children BNFs but they shouldn't be used to determine if they are part of that BNF since the comparator identifiers are.

Overrides:

isCompound in class JPQLQueryBNF

Returns:

false by default
