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, 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.
