Detailed Description

StringTokenizer A class similar to the StringTokenizer from Java. It splits a string at the given string or character (or one of the special cases NEWLINE or WHITECHAR) and allows to iterate over the so generated substrings.

The normal usage is like this:

StringTokenizer st(CString("This is a line"), ' ');
while(st.hasNext())
   cout << st.next() << endl;

This would generate the output:

This
is
a
line

There is something to know about the behaviour: When using WHITECHAR, a list of whitechars occuring in the string to split is regarded as a single divider. All other parameter will use multiple occurrences of operators as a list of single divider and the string between them will have a length of zero.

Constructor & Destructor Documentation

◆ StringTokenizer() [1/4]

StringTokenizer::StringTokenizer ( )

default constructor

Definition at line 45 of file StringTokenizer.cpp.

◆ StringTokenizer() [2/4]

StringTokenizer::StringTokenizer ( std::string  tosplit)

constructor

Parameters
tosplitis the string to split into substrings. If the string between two split positions is empty, it will not be returned.
Note
same as StringTokenizer(tosplit, StringTokenizer.WHITECHARS)

Definition at line 50 of file StringTokenizer.cpp.

References prepareWhitechar().

◆ StringTokenizer() [3/4]

StringTokenizer::StringTokenizer ( std::string  tosplit,
std::string  token,
bool  splitAtAllChars = false 
)

constructor

Note
the first string will be split at the second string's occurrences. If the optional third parameter is true, the string will be split whenever a char from the second string occurs. If the string between two split positions is empty, it will nevertheless be returned.

Definition at line 56 of file StringTokenizer.cpp.

References prepare().

◆ StringTokenizer() [4/4]

StringTokenizer::StringTokenizer ( std::string  tosplit,
int  special 
)

constructor

Note
When StringTokenizer.NEWLINE is used as second parameter, the string will be split at all occurrences of a newline character (0x0d / 0x0a) When StringTokenizer.WHITECHARS is used as second parameter, the string will be split at all characters below 0x20 (SPACE) All other ints specified as second parameter are casted int o a char at which the string will be splitted.
