Constructor & Destructor Documentation

decaf::lang::Character::Character ( char value )

Parameters

value - char to wrap.

Member Function Documentation

virtual unsigned char decaf::lang::Character::byteValue ( ) const

inlinevirtual

Answers the byte value which the receiver represents.

Returns: int the value of the receiver.

Reimplemented from decaf::lang::Number.

virtual int decaf::lang::Character::compareTo ( const Character & c ) const

inlinevirtual

Compares this Character instance with another.

Parameters

c	- the Character instance to be compared

Returns: zero if this object represents the same char value as the argument; a positive value if this object represents a value greater than the passed in value, and -1 if this object repesents a value less than the passed in value.

Implements decaf::lang::Comparable< Character >.

virtual int decaf::lang::Character::compareTo ( const char & c ) const

inlinevirtual

Compares this Character instance with a char type.

Parameters

c	- the char instance to be compared

Returns: zero if this object represents the same char value as the argument; a positive value if this object represents a value greater than the passed in value, and -1 if this object repesents a value less than the passed in value.

Implements decaf::lang::Comparable< char >.

static int decaf::lang::Character::digit	(	char	c,
		int	radix
	)

static

Returns the numeric value of the character ch in the specified radix.

If the radix is not in the range MIN_RADIX <= radix <= MAX_RADIX or if the value of ch is not a valid digit in the specified radix, -1 is returned. A character is a valid digit if at least one of the following is true:

The method isDigit is true of the character and the single-character decomposition is less than the specified radix. In this case the decimal digit value is returned.
The character is one of the uppercase Latin letters 'A' through 'Z' and its code is less than radix + 'A' - 10. In this case, ch - 'A' + 10 is returned.
The character is one of the lowercase Latin letters 'a' through 'z' and its code is less than radix + 'a' - 10. In this case, ch - 'a' + 10 is returned.

Parameters

c	- the char to be converted
radix	- the radix of the number

Returns: the numeric value of the number represented in the given radix

virtual double decaf::lang::Character::doubleValue ( ) const
