Method Details

accept

protected <R,
C> R accept(IrJsonPathVisitor<R,C> visitor,
 C context)

getType

public final Optional<Type> getType()

Get the result type, whenever known. Type might be known for IrPathNodes returning a singleton sequence (e.g. IrArithmeticBinary), as well as for IrPathNodes returning a sequence of arbitrary length (e.g. IrSizeMethod). If the node potentially returns a non-singleton sequence, this method shall return Type only if the type is the same for all elements of the sequence. NOTE: Type is not applicable to every IrPathNode. If the IrPathNode produces an empty sequence, a JSON null, or a sequence containing non-literal JSON items, Type cannot be determined.
