Class UnsignedLong
java.lang.Object
  java.lang.Number
      com.google.common.primitives.UnsignedLong


All Implemented Interfaces: 
Serializable, Comparable<UnsignedLong>



@Beta
@GwtCompatible(serializable=true)
public class UnsignedLong
extends Number
implements Comparable<UnsignedLong>, Serializable

A wrapper class for unsigned long values, supporting arithmetic operations.

In some cases, when speed is more important than code readability, it may be faster simply to treat primitive long values as unsigned, using the methods from UnsignedLongs.

Please do not extend this class; it will be made final in the near future.

Since:

11.0

Field Detail

ZERO

public static final UnsignedLong ZERO

ONE

public static final UnsignedLong ONE

MAX_VALUE

public static final UnsignedLong MAX_VALUE

Constructor Detail

UnsignedLong

protected UnsignedLong(long value)

Method Detail

asUnsigned

public static UnsignedLong asUnsigned(long value)

Returns an UnsignedLong that, when treated as signed, is equal to value. The inverse operation is longValue().

Put another way, if value is negative, the returned result will be equal to 2^64 + value; otherwise, the returned result will be equal to value.

valueOf

public static UnsignedLong valueOf(BigInteger value)

Returns a UnsignedLong representing the same value as the specified BigInteger . This is the inverse operation of bigIntegerValue().

Throws:

IllegalArgumentException - if value is negative or value >= 2^64

valueOf

public static UnsignedLong valueOf(String string)

Returns an UnsignedLong holding the value of the specified String, parsed as an unsigned long value.

Throws:

NumberFormatException - if the string does not contain a parsable unsigned long value

valueOf

public static UnsignedLong valueOf(String string,
                                   int radix)

Returns an UnsignedLong holding the value of the specified String, parsed as an unsigned long value in the specified radix.

Throws:

NumberFormatException - if the string does not contain a parsable unsigned long value, or radix is not between Character.MIN_RADIX and Character.MAX_RADIX

add

public UnsignedLong add(UnsignedLong val)

Returns the result of adding this and val. If the result would have more than 64 bits, returns the low 64 bits of the result.

subtract

public UnsignedLong subtract(UnsignedLong val)

Returns the result of subtracting this and val. If the result would be negative, returns the low 64 bits of the result.

multiply

public UnsignedLong multiply(UnsignedLong val)

Returns the result of multiplying this and val. If the result would have more than 64 bits, returns the low 64 bits of the result.

divide

public UnsignedLong divide(UnsignedLong val)

Returns the result of dividing this by val.

remainder

public UnsignedLong remainder(UnsignedLong val)

Returns the remainder of dividing this by val.

intValue

public int intValue()

Returns the value of this UnsignedLong as an int.

Specified by:

intValue in class Number

longValue

public long longValue()

Returns the value of this UnsignedLong as a long. This is an inverse operation to asUnsigned(long).

Note that if this UnsignedLong holds a value >= 2^63, the returned value will be equal to this - 2^64.

Specified by:

longValue in class Number

floatValue

public float floatValue()

Returns the value of this UnsignedLong as a float, analogous to a widening primitive conversion from long to float, and correctly rounded.

Specified by:

floatValue in class Number

doubleValue

public double doubleValue()

Returns the value of this UnsignedLong as a double, analogous to a widening primitive conversion from long to double, and correctly rounded.

Specified by:

doubleValue in class Number

bigIntegerValue

public BigInteger bigIntegerValue()

Returns the value of this UnsignedLong as a BigInteger.

compareTo

public int compareTo(UnsignedLong o)

Specified by:

compareTo in interface Comparable<UnsignedLong>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(@Nullable
                      Object obj)

Overrides:

equals in class Object

toString

public String toString()

Returns a string representation of the UnsignedLong value, in base 10.

Overrides:

toString in class Object

toString

public String toString(int radix)

Returns a string representation of the UnsignedLong value, in base radix. If radix < Character.MIN_RADIX or radix > Character.MAX_RADIX, the radix 10 is used.
