Method Detail

asBoolean

public boolean asBoolean()
 
Coerce a character to a boolean value. A character is coerced to false if it's character value is equal to 0, and to true otherwise.
Returns:
the boolean value
Since:
1.7.0

compareTo

public int compareTo(Number right)
 
Compare a Character and a Number. The ordinal value of the Character is used in the comparison (the ordinal value is the unicode value which for simple character sets is the ASCII value).
Parameters:
right - a Number.
Returns:
the result of the comparison
Since:
1.0

compareTo

public int compareTo(Character right)
 
Compare two Characters. The ordinal values of the Characters are compared (the ordinal value is the unicode value which for simple character sets is the ASCII value).
Parameters:
right - a Character.
Returns:
the result of the comparison
Since:
1.0

div

public Number div(Number right)
 
Divide a Character by a Number. The ordinal value of the Character is used in the division (the ordinal value is the unicode value which for simple character sets is the ASCII value).
Parameters:
right - a Number.
Returns:
the Number corresponding to the division of left by right
Since:
1.0

div

public Number div(Character right)
 
Divide one Character by another. The ordinal values of the Characters are used in the division (the ordinal value is the unicode value which for simple character sets is the ASCII value).
Parameters:
right - another Character.
Returns:
the Number corresponding to the division of left by right
Since:
1.0

intdiv

public Number intdiv(Number right)
 
Integer Divide a Character by a Number. The ordinal value of the Character is used in the division (the ordinal value is the unicode value which for simple character sets is the ASCII value).
Parameters:
right - a Number.
Returns:
a Number (an Integer) resulting from the integer division operation
Since:
1.0

intdiv

public Number intdiv(Character right)
 
Integer Divide two Characters. The ordinal values of the Characters are used in the division (the ordinal value is the unicode value which for simple character sets is the ASCII value).
Parameters:
right - another Character.
Returns:
a Number (an Integer) resulting from the integer division operation
Since:
1.0

isDigit

public boolean isDigit()
 
Determines if a character is a digit. Synonym for 'Character.isDigit(this)'.
Returns:
true if the character is a digit
Since:
1.5.7
See:
Character#isDigit.

isLetter

public boolean isLetter()
 
Determines if a character is a letter. Synonym for 'Character.isLetter(this)'.
Returns:
true if the character is a letter
Since:
1.5.7
See:
Character#isLetter.

isLetterOrDigit

public boolean isLetterOrDigit()
 
Determines if a character is a letter or digit. Synonym for 'Character.isLetterOrDigit(this)'.
Returns:
true if the character is a letter or digit
Since:
1.5.7
See:
Character#isLetterOrDigit.

isLowerCase

public boolean isLowerCase()
 
Determine if a Character is lowercase. Synonym for 'Character.isLowerCase(this)'.
Returns:
true if the character is lowercase
Since:
1.5.7
See:
Character#isLowerCase.

isUpperCase

public boolean isUpperCase()
 
Determine if a Character is uppercase. Synonym for 'Character.isUpperCase(this)'.
Returns:
true if the character is uppercase
Since:

1.0

minus

public Number minus(Character right)
 
Subtract one Character from another. The ordinal values of the Characters is used in the comparison (the ordinal value is the unicode value which for simple character sets is the ASCII value).
Parameters:
right - a Character.
Returns:
the Number corresponding to the subtraction of right from left
