Fragment

class ReflectExport( reflect ) Fragment

A Fragment is the most basic string type in the reflect string suite.

It consists of a pointer and a length. It does not own its data. It can and should provide any const std::string functions we need that do not require a NUL terminator.

Functions

Fragment

Fragment( const char * s )

Constructs a piece string from a character pointer to NUL terminated data. length is found by strlen() @param s the string to make into a piece string.

find_first_of

size_type find_first_of( const Fragment & ,
size_type pos = 0 ) const

Finds any of a set of characters in the string.

Parameters

s	the set of characters to search for
pos	the position to start from

Returns

index of s in string or npos if not found.

rfind

size_type rfind( const char * s,
size_type pos = npos,
size_type length = npos ) const

Finds a string in the string, in reverse.

Parameters

s	the string to search for
pos	the position to start from

Returns

index of the begining of s in string or npos if not found.

rfind

size_type rfind( const Fragment & s,
size_type pos = npos ) const

Finds a string in the string, in reverse.

Parameters

s	the string to search for
pos	the position to start from

Returns

index of the begining of s in string or npos if not found.

find_last_of

size_type find_last_of( char ch,
size_type pos = npos ) const

Finds a character in the string, in reverse.

Parameters

ch	the character to search for
pos	the position to start from

Returns

index of the last character in string matching ch or npos if not found.

find_last_of

size_type find_last_of( const Fragment & s,
size_type pos = npos ) const

Finds any of a set of characters in the string, in reverse.

Parameters

s	the set of characters to search for
pos	the position to start from

Returns

index of the last character in string contained in s or npos if not found.

substr

Fragment substr( size_type index,
size_type amount = npos ) const

Makes a substr fragment from this one. The substr’s storage is the same as the fragment’s storage.

Parameters

index	the begining of the substring
amount	the maximum length of the substring

Returns

a Fragment substring

empty

bool empty() const

compare

int compare( const Fragment & other ) const

Returns

(+1, 0, or -1)

if the string is (greater, equal, or less) than the other string.
