IntegerLiteralExpr

@Deprecated
public IntegerLiteralExpr(int value)

Deprecated. This function is deprecated in favor of IntegerLiteralExpr(String). Please refer to the asNumber() function for valid formats and how to construct literals holding negative values.

Method Detail

accept

public <R,A> R accept(GenericVisitor<R,A> v,
                      A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Type Parameters:

R - the type of the return value of the visitor

A - the type the user argument passed to the visitor

Parameters:

v - the visitor implementation

arg - the argument passed to the visitor (of type A)

Returns:

the result of the visit (of type R)

accept

public <A> void accept(VoidVisitor<A> v,
                       A arg)

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 implementation

arg - any value relevant for the visitor (of type A)

remove

public boolean remove(Node node)

Overrides:

remove in class LiteralStringValueExpr

asInt

@Deprecated
public int asInt()

Deprecated. This function has issues with corner cases, such as 2147483648, so please use asNumber(). It will be made private or merged with asNumber() in future releases

Returns:

the literal value as an integer while respecting different number representations

asNumber

public Number 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 value 2147483648. This special literal is only allowed in the expression -2147483648 which represents Integer.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 literal 1. It is however possible to represent negative numbers in a literal directly, i.e. by using the binary or hexadecimal representation. For example 0xffff_ffff represents the value -1.

Returns:

the literal value as a number while respecting different number representations

setInt

@Deprecated
public IntegerLiteralExpr setInt(int value)

Deprecated. This function is deprecated in favor of LiteralStringValueExpr.setValue(String). Please refer to the asNumber() function for valid formats and how to construct literals holding negative values.
