Detailed Description

String reference type.

Member Typedef Documentation

typedef StringRef B2bits::StringRef::MyT

typedef char B2bits::StringRef::value_type

Provides access to the template parameter.

Constructor & Destructor Documentation

B2bits::StringRef::StringRef ( )

inlinenoexcept

Default constructor.

B2bits::StringRef::StringRef ( const value_type *  aData, size_t  aSize  )

inlinenoexcept

Constructor Constructs instance from address to memory and size

Parameters

aData	address to the block
aSize	size of the block

template<typename Iterator >

B2bits::StringRef::StringRef ( Iterator  aBegin, Iterator  aEnd  )

inlinenoexcept

Constructor Constructs instance from address to memory and size

Parameters

aBegin	address to the first byte of the block
aEnd	address of the byte after last byte of the block

B2bits::StringRef::StringRef ( std::string const &  str )

inlinenoexcept

Constructor Constructs instance from std::basic_string.

Parameters

str	Source std::string

B2bits::StringRef::StringRef ( value_type const *  aData )

inlinenoexcept

Constructor Constructs instance from ANSI std::string

Parameters

aData

address to the ASCII std::string

Member Function Documentation

static int B2bits::StringRef::cmpAsFixedSizeStr ( MyT  v1, MyT  v2  )

staticnoexcept

Compares two strings with known memory size but unknown actual data size. Fox example "abc\0\0\0\0" and "abc\0" Usefull for fixed size strings.

int B2bits::StringRef::compareTo ( StringRef  rv ) const

inlinenoexcept

bool B2bits::StringRef::equals ( StringRef  rv ) const

inlinenoexcept

template<int N>

static MyT B2bits::StringRef::fromStr ( value_type const (&)  aData[N] )

inlinestaticnoexcept

Creates instance from array of char

Parameters

aData

Array of chars

bool B2bits::StringRef::isEmpty ( ) const

inlinenoexcept

Returns true if given string is empty (e.g. size equal to 0)

bool B2bits::StringRef::isNull ( ) const

inlinenoexcept

Returns true if given string is NULL.

MyT B2bits::StringRef::normalize ( ) const

noexcept

Calculates size of string and returns new object of StringRef.

StringRef B2bits::StringRef::substr ( std::size_t  offset, std::size_t  size  ) const

inlinenoexcept

Returns part of the string by given offset and size.

StringRef B2bits::StringRef::substr ( std::size_t  offset ) const

inlinenoexcept

Returns part of the string by given offset till end of string.

int B2bits::StringRef::toInt ( ) const

noexcept

Converts string value to int.

i16 B2bits::StringRef::toInt16 ( ) const

noexcept

Converts string value to int.

i32 B2bits::StringRef::toInt32 ( ) const

noexcept

Converts string value to int.

i64 B2bits::StringRef::toInt64 ( ) const

noexcept

Converts string value to int.

std::basic_string<value_type> B2bits::StringRef::toStdString ( ) const

inline

Converts AsciiString to std::string. This method creates copy of the stored buffer and returns it as std::string.

unsigned int B2bits::StringRef::toUInt ( ) const

noexcept

Converts string value to int.

u16 B2bits::StringRef::toUInt16 ( ) const

noexcept

Converts string value to int.

u32 B2bits::StringRef::toUInt32 ( ) const

noexcept

Converts string value to int.

u64 B2bits::StringRef::toUInt64 ( ) const

noexcept

Converts string value to int.
