public class MutableLong extends Number implements Comparable<MutableLong>, Mutable<Number>
long wrapper.
Note that as MutableLong does not extend Long, it is not treated by String.format as a Long parameter.

MutableLong()
Constructs a new MutableLong with the default value of zero.
|
MutableLong(long value)
Constructs a new MutableLong with the specified value.
|
MutableLong(Number value)
Constructs a new MutableLong with the specified value.
|
MutableLong(String value)
Constructs a new MutableLong parsing the given string.
|
| Modifier and Type | Method and Description |
|---|---|
void |
add(long operand)
Adds a value to the value of this instance.
|
void |
add(Number operand)
Adds a value to the value of this instance.
|
long |
addAndGet(long operand)
Increments this instance's value by
operand; this method returns the value associated with the instance
immediately after the addition operation. |
long |
addAndGet(Number operand)
Increments this instance's value by
operand; this method returns the value associated with the instance
immediately after the addition operation. |
int |
compareTo(MutableLong other)
Compares this mutable to another in ascending order.
|
void |
decrement()
Decrements the value.
|
long |
decrementAndGet()
Decrements this instance's value by 1; this method returns the value associated with the instance
immediately after the decrement operation.
|
double |
doubleValue()
Returns the value of this MutableLong as a double.
|
boolean |
equals(Object obj)
Compares this object to the specified object.
|
float |
floatValue()
Returns the value of this MutableLong as a float.
|
long |
getAndAdd(long operand)
Increments this instance's value by
operand; this method returns the value associated with the instance
immediately prior to the addition operation. |
long |
getAndAdd(Number operand)
Increments this instance's value by
operand; this method returns the value associated with the instance
immediately prior to the addition operation. |
long |
getAndDecrement()
Decrements this instance's value by 1; this method returns the value associated with the instance
immediately prior to the decrement operation.
|
long |
getAndIncrement()
Increments this instance's value by 1; this method returns the value associated with the instance
immediately prior to the increment operation.
|
Long |
getValue()
Gets the value as a Long instance.
|
int |
hashCode()
Returns a suitable hash code for this mutable.
|
void |
increment()
Increments the value.
|
long |
incrementAndGet()
Increments this instance's value by 1; this method returns the value associated with the instance
immediately after the increment operation.
|
int |
intValue()
Returns the value of this MutableLong as an int.
|
long |
longValue()
Returns the value of this MutableLong as a long.
|
void |
setValue(long value)
Sets the value.
|
void |
setValue(Number value)

|
void |
subtract(long operand)
Subtracts a value from the value of this instance.
|
void |
subtract(Number operand)
Subtracts a value from the value of this instance.
|
Long |
toLong()
