Detailed Description

A byte vector.

This class provides an implicitly shared byte vector with some methods that are useful for tagging purposes. Many of the search functions are tailored to what is useful for finding tag related patterns in a data array.

Warning
The behavior is undefined if data is not null terminated.

References data().

◆ ~ByteVector()

Destroys this ByteVector instance.

Member Function Documentation

◆ append() [1/2]

ByteVector & TagLib::ByteVector::append ( char c)

Appends c to the end of the ByteVector.

References ByteVector().

◆ append() [2/2]

ByteVector & TagLib::ByteVector::append ( const ByteVector & v)

Appends v to the end of the ByteVector.

References ByteVector().

◆ at()

char TagLib::ByteVector::at ( unsigned int index) const

This essentially performs the same as operator[](), but instead of causing a runtime error if the index is out of bounds, it will return a null byte.

◆ begin() [1/2]

Iterator TagLib::ByteVector::begin ( )

Returns an Iterator that points to the front of the vector.

◆ begin() [2/2]

ConstIterator TagLib::ByteVector::begin ( ) const

Returns a ConstIterator that points to the front of the vector.

◆ cbegin()

ConstIterator TagLib::ByteVector::cbegin ( ) const

Returns a ConstIterator that points to the front of the vector.

◆ cend()

ConstIterator TagLib::ByteVector::cend ( ) const

Returns a ConstIterator that points to the back of the vector.

◆ clear()

ByteVector & TagLib::ByteVector::clear ( )

Clears the data.

References ByteVector().

◆ containsAt()

bool TagLib::ByteVector::containsAt ( const ByteVector & pattern,
unsigned int offset,
unsigned int patternOffset = 0,
unsigned int patternLength = 0xffffffff ) const

Checks to see if the vector contains the pattern starting at position offset. Optionally, if you only want to search for part of the pattern you can specify an offset within the pattern to start from. Also, you can specify to only check for the first patternLength bytes of pattern with the patternLength argument.

References ByteVector().

◆ data() [1/2]

char * TagLib::ByteVector::data ( )

Returns a pointer to the internal data structure.

Warning
Care should be taken when modifying this data structure as it is easy to corrupt the ByteVector when doing so. Specifically, while the data may be changed, its length may not be.

Referenced by ByteVector(), ByteVector(), operator=(), and setData().

◆ data() [2/2]

const char * TagLib::ByteVector::data ( ) const

Returns a pointer to the internal data structure which may not be modified.

◆ detach()

void TagLib::ByteVector::detach ( )
protected

If this ByteVector is being shared via implicit sharing, do a deep copy of the data and separate from the shared members. This should be called by all non-const subclass members.

References TAGLIB_MSVC_SUPPRESS_WARNING_NEEDS_TO_HAVE_DLL_INTERFACE.

◆ end() [1/2]

Iterator TagLib::ByteVector::end ( )

Returns an Iterator that points to the back of the vector.

ConstIterator TagLib::ByteVector::end ( ) const

Returns a ConstIterator that points to the back of the vector.

bool TagLib::ByteVector::endsWith ( const ByteVector & pattern) const

Returns true if the vector ends with pattern.

References ByteVector().

◆ endsWithPartialMatch()

int TagLib::ByteVector::endsWithPartialMatch ( const ByteVector & pattern) const

Checks for a partial match of pattern at the end of the vector. It returns the offset of the partial match within the vector, or -1 if the pattern is not found. This method is particularly useful when searching for patterns that start in one vector and end in another. When combined with startsWith() it can be used to find a pattern that overlaps two buffers.

Note
This will not match the complete pattern at the end of the string; use endsWith() for that.

References ByteVector().

◆ find() [1/2]

int TagLib::ByteVector::find ( char c,
unsigned int offset = 0,
int byteAlign = 1 ) const

Searches the char for c starting at offset and returns the offset. Returns -1 if the pattern was not found. If byteAlign is specified the pattern will only be matched if it starts on a byte divisible by byteAlign (starting from offset).

◆ find() [2/2]

int TagLib::ByteVector::find ( const ByteVector & pattern,
unsigned int offset = 0,
int byteAlign = 1 ) const

Searches the ByteVector for pattern starting at offset and returns the offset. Returns -1 if the pattern was not found. If byteAlign is specified the pattern will only be matched if it starts on a byte divisible by byteAlign (starting from offset).
