Constructor Detail
MutableBoolean
public MutableBoolean()(Code)
Constructs a new MutableBoolean with the default value of false.



MutableBoolean
public MutableBoolean(boolean value)(Code)
Constructs a new MutableBoolean with the specified value.
Parameters:
  value - a value.



MutableBoolean
public MutableBoolean(Boolean value)(Code)
Constructs a new MutableBoolean with the specified value.
Parameters:
  value - a value.
throws:
  NullPointerException - if the object is null




Method Detail
booleanValue
public boolean booleanValue()(Code)
Returns the value of this MutableBoolean as a boolean. the boolean value represented by this object.



compareTo
public int compareTo(Object obj)(Code)
Compares this mutable to another in ascending order.
Parameters:
  obj - the mutable to compare to zero if this object represents the same boolean value as the argument; a positive value if this objectrepresents true and the argument represents false; and a negative value if this object represents falseand the argument represents true
throws:
  ClassCastException - if the argument is not a MutableInt



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 MutableBoolean object that contains the same boolean value as this object.
Parameters:
  obj - the object to compare with. true if the objects are the same; false otherwise.



getValue
public Object getValue()(Code)
Gets the value as a Boolean instance. the value as a Boolean



hashCode
public int hashCode()(Code)
Returns a suitable hashcode for this mutable. the integer 1231 if this object represents true; returns the integer1237 if this object represents false.



setValue
public void setValue(boolean value)(Code)
Sets the value.
Parameters:
  value - the value to set



setValue
public void setValue(Object value)(Code)
Sets the value from any Boolean instance.
Parameters:
  value - the value to set
throws:
  NullPointerException - if the object is null
throws:
  ClassCastException - if the type is not a Boolean



toString
public String toString()(Code)
Returns the String value of this mutable. the mutable value as a string
