TStringLong
TString
Basic string class.
Cannot be stored in a TCollection... use TObjString instead.
Ssiz_t GetInitialCapacity()
Ssiz_t GetResizeIncrement()
Ssiz_t GetMaxWaste()
______________________________________________________________________________
TString()
TString default ctor.
TString(Ssiz_t ic)
Create TString able to contain ic characters.
TString(const char* cs)
Create TString and initialize it with string cs.
TString(const char* cs, Ssiz_t n)
Create TString and initialize it with the first n characters of cs.
void InitChar(char c)
Initialize a string with a single character.
TString(char c, Ssiz_t n)
Initialize the first n locations of a TString with character c.
TString(const TSubString& substr)
Copy a TSubString in a TString.
~TString()
Delete a TString. I.e. decrease its reference count. When 0 free space.
TString Append(char c, Ssiz_t rep)
Append character c rep times to string.
Ssiz_t Capacity(Ssiz_t nc)
Return string capacity. If nc != current capacity Clone() the string
in a string with the desired capacity.
int CompareTo(const char* cs2, ECaseCompare cmp) const
Compare a string to char *cs2.
int CompareTo(const TString& str, ECaseCompare cmp) const
Compare a string to another string.
TString Copy() const
Copy a string.
unsigned Hash(ECaseCompare cmp) const
Return hash value.
Ssiz_t Index(const char* pattern, Ssiz_t plen, Ssiz_t startIndex,
ECaseCompare cmp) const
Search for a string in the TString. Plen is the length of pattern,
startIndex is the index from which to start and cmp selects the type
of case-comparison.
Bool_t MaybeRegexp()
Returns true if string contains one of the regexp characters "^$.[]*+?".
TString Prepend(char c, Ssiz_t rep)
Prepend characters to self.
TString Replace(Ssiz_t pos, Ssiz_t n1, const char* cs, Ssiz_t n2)
Remove at most n1 characters from self beginning at pos,
and replace them with the first n2 characters of cs.
TString ReplaceAll(const char *s1, Ssiz_t ls1, const char *s2, Ssiz_t ls2)
Find & Replace ls1 symbols of s1 with ls2 symbols of s2 if any.
void Resize(Ssiz_t n)
Resize the string. Truncate or add blanks as necessary.
TSubString Strip(EStripType st, char c)
Return a substring of self stripped at beginning and/or end.
TSubString Strip(EStripType st, char c) const
Just use the "non-const" version, adjusting the return type.
void ToLower()
Change string to lower-case.
void ToUpper()
Change string to upper case.
void AssertElement(Ssiz_t i) const
Check to make sure a string index is in range.
TString(const char* a1, Ssiz_t n1, const char* a2, Ssiz_t n2)
Special constructor to initialize with the concatenation of a1 and a2.
Ssiz_t AdjustCapacity(Ssiz_t nc)
Calculate a nice capacity greater than or equal to nc.
void Clobber(Ssiz_t nc)
Clear string and make sure it has a capacity of nc.
void Clone()
Make string a distinct copy; preserve previous contents.
void Clone(Ssiz_t nc)
Make self a distinct copy with capacity of at least nc.
Preserve previous contents.
void FillBuffer(char *&buffer)
Copy string into I/O buffer.
void ReadBuffer(char *&buffer)
Read string from I/O buffer.
TString* ReadString(TBuffer &b, const TClass *clReq)
Read TString object from buffer. Simplified version of
TBuffer::ReadObject (does not keep track of multiple
references to same string). We need to have it here
because TBuffer::ReadObject can only handle descendant
of TObject
Int_t Sizeof() const
Returns size string will occupy on I/O buffer.
void Streamer(TBuffer &b)
Stream a string object
void WriteString(TBuffer &b, const TString *a)
Write TString object to buffer. Simplified version of
TBuffer::WriteObject (does not keep track of multiple
references to the same string). We need to have it here
because TBuffer::ReadObject can only handle descendant
of TObject
Ssiz_t InitialCapacity(Ssiz_t ic)
Set default initial capacity for all TStrings. Default is 15.
Ssiz_t ResizeIncrement(Ssiz_t ri)
Set default resize increment for all TStrings. Default is 16.
Ssiz_t MaxWaste(Ssiz_t mw)
Set maximum space that may be wasted in a string before doing a resize.
Default is 15.
TSubString SubString(const char* pattern, Ssiz_t startIndex,
ECaseCompare cmp)
Returns a substring matching "pattern", or the null substring
if there is no such match. It would be nice if this could be yet another
overloaded version of operator(), but this would result in a type
conversion ambiguity with operator(Ssiz_t, Ssiz_t).
TSubString SubString(const char* pattern, Ssiz_t startIndex,
ECaseCompare cmp) const
Return sub-string matching pattern, starting at index. Cmp selects
the type of case conversion.
Bool_t IsAscii() const
Return true if all characters in string are ascii.
Bool_t EndsWith(const char *s, ECaseCompare cmp) const
