Detailed Description

Representation of character strings.

Strings are internally stored as an Ascii character array. The positions within a string a numbered 0,1,...

Constructor & Destructor Documentation

ogdf::String::String

(

)

Constructs an empty string, i.e., a string with length 0.

ogdf::String::String

(

const char

c

)

Constructs a string consisting of a single character c.

ogdf::String::String

(

const char *

str

)

Constructs a string that is a copy of str.

ogdf::String::String	(	size_t	maxLen,
		const char *	str
	)

Constructs a string consisting of the first maxLen characters of str.

Parameters:

	maxLen	is the number of characters to be copied from the begin of str. If str is shorter than maxLen or maxLen is -1, then the complete string is copied.
	str	is the string to be copied.

ogdf::String::String

(

const String &

str

)

Constructs a string that is a copy of str.

ogdf::String::~String
