Constructor Detail MutableInt public MutableInt()(Code) Constructs a new MutableInt with the default value of zero. MutableInt public MutableInt(int value)(Code) Constructs a new MutableInt with the specified value. Parameters:   value - a value. MutableInt public MutableInt(Number value)(Code) Constructs a new MutableInt with the specified value. Parameters:   value - a value. throws:   NullPointerException - if the object is null Method Detail add public void add(int operand)(Code) Adds a value. Parameters:   operand - the value to add since:    Commons Lang 2.2 add public void add(Number operand)(Code) Adds a value. Parameters:   operand - the value to add throws:   NullPointerException - if the object is null since:    Commons Lang 2.2 compareTo public int compareTo(Object obj)(Code) Compares this mutable to another in ascending order. Parameters:   obj - the mutable to compare to negative if this is less, zero if equal, positive if greater throws:   ClassCastException - if the argument is not a MutableInt decrement public void decrement()(Code) Decrements the value. since:    Commons Lang 2.2 doubleValue public double doubleValue()(Code) Returns the value of this MutableInt as a double. the numeric value represented by this object after conversion to type double. equals public boolean equals(Object obj)(Code) Compares this object to the specified object. The result is true if and only if the argument is not null and is an MutableInt object that contains the same int value as this object. Parameters:   obj - the object to compare with. true if the objects are the same; false otherwise. floatValue public float floatValue()(Code) Returns the value of this MutableInt as a float. the numeric value represented by this object after conversion to type float. getValue public Object getValue()(Code) Gets the value as a Integer instance. the value as a Integer hashCode public int hashCode()(Code) Returns a suitable hashcode for this mutable. a suitable hashcode increment public void increment()(Code) Increments the value. since:    Commons Lang 2.2 intValue public int intValue()(Code) Returns the value of this MutableInt as a int. the numeric value represented by this object after conversion to type int. longValue public long longValue()(Code) Returns the value of this MutableInt as a long. the numeric value represented by this object after conversion to type long. setValue public void setValue(int value)(Code) Sets the value. Parameters:   value - the value to set setValue public void setValue(Object value)(Code) Sets the value from any Number instance. Parameters:   value - the value to set throws:   NullPointerException - if the object is null throws:   ClassCastException - if the type is not a Number subtract public void subtract(int operand)(Code) Subtracts a value. Parameters:   operand - the value to add since:    Commons Lang 2.2 subtract public void subtract(Number operand)(Code) Subtracts a value. Parameters:   operand - the value to add throws:   NullPointerException - if the object is null since:    Commons Lang 2.2 toInteger public Integer toInteger()(Code) Gets this mutable as an instance of Integer. a Integer instance containing the value from this mutable toString public String toString()(Code) Returns the String value of this mutable. the mutable value as a string Methods inherited from java.lang.Number public byte byteValue()(Code)(Java Doc) abstract public double doubleValue()(Code)(Java Doc) abstract public float floatValue()(Code)(Java Doc) abstract public int intValue()(Code)(Java Doc) abstract public long longValue()(Code)(Java Doc) public short shortValue()(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
