| Field Summary | |
| final public static Boolean | FALSE
The instance of the receiver which represents falsehood. | | final public static Boolean | TRUE
The instance of the receiver which represents truth. | | final public static Class<Boolean> | TYPE
The
java.lang.Class that represents this class. |
| Constructor Summary | |
| public | Boolean(String string)
Constructs a new instance of this class given a string. | | public | Boolean(boolean value)
Constructs a new instance of this class given true or false. |
| Method Summary | |
| public boolean | booleanValue()
Answers true if the receiver represents true and false if the receiver
represents false. | | public int | compareTo(Boolean that)
Compares this Boolean to another Boolean.
If this instance has the same value as the instance passed, then
0 is returned. | | public boolean | equals(Object o)
Compares the argument to the receiver, and answers true if they represent
the same object using a class specific comparison.
In this case, the argument must also be a Boolean, and the receiver and
argument must represent the same boolean value (i.e. | | public static boolean | getBoolean(String string)
Answers true if the system property described by the argument equal to
"true" using case insensitive comparison, and false otherwise.
Parameters:
string - The name of the desired boolean. | | public int | hashCode()
Answers an integer hash code for the receiver. | | public static boolean | parseBoolean(String s)
Parses the string as a boolean. | | public String | toString()
Answers a string containing a concise, human-readable description of the
receiver. | | public static String | toString(boolean value)
Converts the specified boolean to its string representation. | | public static Boolean | valueOf(String string)
Answers a Boolean representing true if the argument is equal to "true"
using case insensitive comparison, and a Boolean representing false
otherwise.
Parameters:
string - The name of the desired boolean. | | public static Boolean | valueOf(boolean b)
Answers Boolean.TRUE if the argument is equal to "true" using case
insensitive comparison, and Boolean.FALSE representing false otherwise.
Parameters:
b - the boolean value. |
| FALSE | | final public static Boolean FALSE(Code) | | The instance of the receiver which represents falsehood.
|
| TRUE | | final public static Boolean TRUE(Code) | | The instance of the receiver which represents truth.

| Boolean | | public Boolean(String string)(Code) | | Constructs a new instance of this class given a string. If the string is
equal to "true" using a non-case sensitive comparison, the result will be
a Boolean representing true, otherwise it will be a Boolean representing
false.
Parameters:
string - The name of the desired boolean. |
| Boolean | | public Boolean(boolean value)(Code) | | Constructs a new instance of this class given true or false.
Parameters:
value - true or false. |
| booleanValue | | public boolean booleanValue()(Code) | | Answers true if the receiver represents true and false if the receiver
represents false.
true or false. |
| compareTo | | public int compareTo(Boolean that)(Code) | | Compares this Boolean to another Boolean.
If this instance has the same value as the instance passed, then
0 is returned. If this instance is true and
the instance passed is false, then a positive value is
returned. If this instance is false and the instance
passed is true, then a negative value is returned.
Parameters:
that - The instance to compare to.
throws:
NullPointerException - if that is null.

| equals | | public boolean equals(Object o)(Code) | | Compares the argument to the receiver, and answers true if they represent
the same object using a class specific comparison.
In this case, the argument must also be a Boolean, and the receiver and
argument must represent the same boolean value (i.e. both true or both
false).
Parameters:
o - the object to compare with this object true if the object is the same as this objectfalse if it is different from this object

| getBoolean | | public static boolean getBoolean(String string)(Code) | | Answers true if the system property described by the argument equal to
"true" using case insensitive comparison, and false otherwise.
Parameters:
string - The name of the desired boolean. The boolean value. |
| hashCode | | public int hashCode()(Code) | | Answers an integer hash code for the receiver. Any two objects which
answer true when passed to equals must
answer the same value for this method.
the receiver's hash

| parseBoolean | | public static boolean parseBoolean(String s)(Code) | | Parses the string as a boolean. If the string is not
null and is equal to "true", regardless
case, then true is returned, otherwise false.
Parameters:
s - The string to parse. A boolean value.

| toString | | public String toString()(Code) | | Answers a string containing a concise, human-readable description of the
receiver.
a printable representation for the receiver. |
| toString | | public static String toString(boolean value)(Code) | | Converts the specified boolean to its string representation. When the
boolean is true answer "true", otherwise answer
"false".
Parameters:
value - the boolean the boolean converted to a string |
| valueOf | | public static Boolean valueOf(String string)(Code) | | Answers a Boolean representing true if the argument is equal to "true"
using case insensitive comparison, and a Boolean representing false
otherwise.
Parameters:
string - The name of the desired boolean. the boolean value. |
| valueOf | | public static Boolean valueOf(boolean b)(Code) | | Answers Boolean.TRUE if the argument is equal to "true" using case
insensitive comparison, and Boolean.FALSE representing false otherwise.
Parameters:
b - the boolean value. Boolean.TRUE or Boolean.FALSE Global true/false objects. |
