bool S::endsWith

(

const String &

s )

const

Tests whether this string ends with the specified suffix

Returns:

true if the character sequence represented by the argument is a suffix of the character sequence represented by this object; return false otherwise. Note that the result will be true if the argument is the empty string.

long S::find	(	const String &	s,
		unsigned long	start = 0
	)		const

Returns the index within this string of the first occurrence of the specified substring, starting at the specified index.

Parameters:

s	the substring to find
start	the position from which to start the search.

Returns:

the position of the first occurence of the substring. If not found, return -1;

String S::getClassName

(

)

const [virtual]

Returns the name of the class

Returns:

the name of the class of the object as a String

Implements alize::Object.

Definition at line 417 of file alizeString.cpp.

S S::getToken	(	unsigned long	index,
		const String &	sep = " "
	)		const

Finds the token number 'index' in this string
Example : string = " aaa bbb ccc "
getToken(0) will return "aaa"
getToken(1) will return "bbb"
getToken(2) will return "ccc"
getToken(3 and more) will return ""

Parameters:

index	index of the token to return
sep	Separator. A single character. Default is " ".

Returns:

a string with the token if it exists; return an empty string otherwise
