TString

Basic string class.

Cannot be stored in a TCollection... use TObjString instead.

The underlying string is stored as a char* that can be accessed via
TString::Data().
TString provides copy-on-write semantics with reference counting
so that multiple TString objects can refer to the same data.
For example:
root [0] TString orig("foo")
root [1] TString copy(orig)  // 'orig' and 'copy' point to the
 same data...
root [2] orig.Data()
(const char* 0x98936f8)"foo"
root [3] copy.Data()
(const char* 0x98936f8)"foo"
root [4] copy="bar"          // Editing 'copy' makes it point
                                // elsewhere
(class TString)"bar"
root [5] copy.Data()
(const char* 0x98939b8)"bar"

Substring operations are provided by the TSubString class, which
holds a reference to the original string and its data, along with
the offset and length of the substring. To retrieve the substring
as a TString, construct a TString from it, eg:
root [0] TString s("hello world")
root [1] TString s2( s(0,5) )
root [2] s2
(class TString)"hello"

This class is also known as (typedefs to this class)

UInt_t Hash(TString::ECaseCompare cmp = kExact) const
 Return hash value.
UInt_t Hash(const void* txt, Int_t ntxt)
 Calculates hash index from any char string. (static function)
 Based on precalculated table of 256 specially selected numbers.
 These numbers are selected in such a way, that for string
 length == 4 (integer number) the hash is unambigous, i.e.
 from hash value we can recalculate input (no degeneration).

 The quality of hash method is good enough, that
 "random" numbers made as R = Hash(1), Hash(2), ...Hash(N)
 tested by <R>, <R*R>, <Ri*Ri+1> gives the same result
 as for libc rand().

 For string:  i = TString::Hash(string,nstring);
 For int:     i = TString::Hash(&intword,sizeof(int));
 For pointer: i = TString::Hash(&pointer,sizeof(void*));

TString * ReadString(TBuffer& b, const TClass* clReq)
 Read TString object from buffer. Simplified version of
 TBuffer::ReadObject (does not keep track of multiple

 integer strings whose Atoi() value is 123456.
Long64_t Atoll() const
 Return long long value of string.
 Valid strings include only digits and whitespace (see IsDigit()),
 i.e. "123456", "123 456" and "1 2 3 4        56" are all valid

 Return true if string ends with the specified string.
TObjArray * Tokenize(const TString& delim) const
 This function is used to isolate sequential tokens in a TString.
 These tokens are separated in the string by at least one of the
 characters in delim. The returned array contains the tokens
 as TObjString's. The returned array is the owner of the objects,
 and must be deleted by the user.
