Properties

int hashCode #

Get a hash code for this object.

All objects have hash codes. Hash codes are guaranteed to be the same for objects that are equal when compared using the equality operator ==. Other than that there are no guarantees about the hash codes. They will not be consistent between runs and there are no distribution guarantees.

If a subclass overrides hashCode it should override the equality operator as well to maintain consistency.

Operators

abstract intx operator +(other) #

abstract intx operator -() #

abstract intx operator -(other) #

abstract intx operator *(other) #

abstract intx operator ~/(other) #

abstract intx operator %(other) #

abstract intx operator &(other) #

abstract intx operator |(other) #

abstract intx operator ^(other) #

abstract intx operator ~() #

abstract intx operator <<(int shiftAmount) #

abstract intx operator >>(int shiftAmount) #

abstract bool operator <(other) #

abstract bool operator <=(other) #

abstract bool operator >(other) #

abstract bool operator >=(other) #

abstract bool operator ==(other) #

The equality operator.

The default behavior for all Objects is to return true if and only if this and other are the same object.

If a subclass overrides the equality operator it should override the hashCode method as well to maintain consistency.

Methods

abstract intx abs() #

abstract int compareTo(Comparable other) #

Compares this object to another Comparable

Returns a value like a Comparator when comparing this to other.

May throw an ArgumentError if other is of a type that is not comparable to this.

abstract bool isEven() #

abstract bool isMaxValue() #

abstract bool isMinValue() #

abstract bool isNegative() #

abstract bool isOdd() #

abstract bool isZero() #

abstract int numberOfLeadingZeros() #

Returns the number of leading zeros in this intx as an int between 0 and 64.

abstract int numberOfTrailingZeros() #

Returns the number of trailing zeros in this intx as an int between 0 and 64.

abstract intx remainder(other) #

abstract intx shiftRightUnsigned(int shiftAmount) #

abstract List<int> toBytes() #

Converts this intx to a List of int, starting with the least significant byte.

abstract String toHexString() #

Returns the value of this intx as a hexadecimal String.

abstract int toInt() #

Converts this intx to an int. On some platforms, inputs with large absolute values (i.e., > 2^52) may lose some of their low bits.

abstract int32 toInt32() #

Converts an intx to 32 bits. Narrower values are sign extended and wider values have their high bits truncated.

abstract int64 toInt64() #

Converts an intx to 64 bits.

abstract String toRadixString(int radix) #

Returns the value of this intx as a String in the given radix. radix must be an integer between 2 and 16, inclusive.

abstract String toString() #

Returns the value of this intx as a decimal String.
