  - MutableBoolean
```
public MutableBoolean()
```
    Constructs a new MutableBoolean with the default value of false.
  - MutableBoolean
```
public MutableBoolean(boolean value)
```
    Constructs a new MutableBoolean with the specified value.
    
    Parameters:
    
    value - the initial value to store
  - MutableBoolean
```
public MutableBoolean(Boolean value)
```
    Constructs a new MutableBoolean with the specified value.
    
    Parameters:
    
    value - the initial value to store, not null
    
    Throws:
    
    NullPointerException - if the object is null
- Method Detail
  - getValue
```
public Object getValue()
```
    Gets the value as a Boolean instance.
    
    Specified by:
    
    getValue in interface Mutable
    
    Returns:
    
    the value as a Boolean, never null
  - setValue
```
public void setValue(boolean value)
```
    Sets the value.
    
    Parameters:
    
    value - the value to set
  - setValue
```
public void setValue(Object value)
```
    Sets the value from any Boolean instance.
    
    Specified by:
    
    setValue in interface Mutable
    
    Parameters:
    
    value - the value to set, not null
    
    Throws:
    
    NullPointerException - if the object is null
  - isTrue
```
public boolean isTrue()
```
    Checks if the current value is true.
    
    Returns:
    
    true if the current value is true
    
    Since:
    
    2.5
  - isFalse
```
public boolean isFalse()
```
    Checks if the current value is false.
    
    Returns:
    
    true if the current value is false
    
    Since:
    
    2.5
  - booleanValue
```
public boolean booleanValue()
```
    Returns the value of this MutableBoolean as a boolean.
    
    Returns:
    
    the boolean value represented by this object.
  - toBoolean
```
public Boolean toBoolean()
```
    Gets this mutable as an instance of Boolean.
    
    Returns:
    
    a Boolean instance containing the value from this mutable, never null
    
    Since:
    
    2.5
  - equals
```
public boolean equals(Object obj)
```
    Compares this object to the specified object. The result is true if and only if the argument is not null and is an MutableBoolean object that contains the same boolean value as this object.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the object to compare with, null returns false
    
    Returns:
    
    true if the objects are the same; false otherwise.
  - hashCode
```
public int hashCode()
```
    Returns a suitable hash code for this mutable.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code returned by Boolean.TRUE or Boolean.FALSE
  - compareTo
```
public int compareTo(Object obj)
```
    Compares this mutable to another in ascending order.
    
    Specified by:
    
    compareTo in interface Comparable
    
    Parameters:
    
    obj - the other mutable to compare to, not null
    
    Returns:
    
    negative if this is less, zero if equal, positive if greater where false is less than true
  - toString
```
public String toString()
```
    Returns the String value of this mutable.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    the mutable value as a string
