accept
Description copied from interface:Visitable
Accept method for visitor support.- Type Parameters:
R
- the type of the return value of the visitorA
- the type the user argument passed to the visitor- Parameters:
v
- the visitor implementationarg
- the argument passed to the visitor (of type A)- Returns:
- the result of the visit (of type R)
-
accept
Description copied from interface:Visitable
Accept method for visitor support.- Type Parameters:
A
- the type the argument passed for the visitor- Parameters:
v
- the visitor implementationarg
- any value relevant for the visitor (of type A)

asInt
Deprecated.This function has issues with corner cases, such as 2147483648, so please useasNumber()
. It will be made private or merged withasNumber()
in future releases- Returns:
- the literal value as an integer while respecting different number representations
-
asNumber
This function returns a representation of the literal value as a number. This will return an integer, except for the case when the literal has the value2147483648
. This special literal is only allowed in the expression-2147483648
which representsInteger.MIN_VALUE
). However 2147483648 (2^31) is out of range of int, which is -(2^31) to (2^31)-1 and thus a long must be returned.Note, that this function will NOT return a negative number if the literal was specified in decimal, since according to the language specification (chapter 3.10.1) an expression such as
-1
is represented by a unary expression with a minus operator and the literal1
. It is however possible to represent negative numbers in a literal directly, i.e. by using the binary or hexadecimal representation. For example0xffff_ffff
represents the value-1
.- Returns:
- the literal value as a number while respecting different number representations
-
setInt
