Méthodes publiques

Méthode	Description
ExifBitConverter ( IComputerArchitectureInfo computerArchitectureInfo ) : System	Initializes a new instance of the ExifBitConverter class.
GetBytes ( Rational value ) : byte[]	Converts the given signed rational number to an array of bytes.
GetBytes ( Rational value ) : byte[]	Converts the given unsigned rational number to an array of bytes.
GetBytes ( string value ) : byte[]	Converts the given ascii string to an array of bytes without adding a null terminator.
GetBytes ( string value, bool addnull ) : byte[]	Converts the given ascii string to an array of bytes optionally adding a null terminator.
IsLittleEndian ( ) : bool	Indicates the byte order ("endianness") in which data is converted using this class. Different computer architectures store data using different byte orders. "Big-endian" means the most significant byte is on the left end of a word. "Little-endian" means the most significant byte is on the right end of a word.

Méthodes protégées

Méthode	Description
CopyBytesImpl ( long value, int bytes, byte buffer, int index ) : void	Copies the given number of bytes from the least-specific end of the specified value into the specified byte array, beginning at the specified index. This must be implemented in concrete derived classes, but the implementation may assume that the value will fit into the buffer.
FromBytes ( byte value, int startIndex, int bytesToConvert ) : long	Convert the given number of bytes from the given array, from the given start position, into a long, using the bytes as the least significant part of the long. By the time this is called, the arguments have been checked for validity.

Method Details

CopyBytesImpl() protected méthode

Copies the given number of bytes from the least-specific end of the specified value into the specified byte array, beginning at the specified index. This must be implemented in concrete derived classes, but the implementation may assume that the value will fit into the buffer.

protected CopyBytesImpl ( long value, int bytes, byte buffer, int index ) : void
value	long	The value to copy bytes for
bytes	int	The number of significant bytes to copy
buffer	byte	The byte array to copy the bytes into
index	int	The first index into the array to copy the bytes into
Résultat	void

ExifBitConverter() public méthode

Initializes a new instance of the ExifBitConverter class.

public ExifBitConverter ( IComputerArchitectureInfo computerArchitectureInfo ) : System
computerArchitectureInfo	IComputerArchitectureInfo	/// The computer architecture info. ///
Résultat	System

FromBytes() protected méthode

Convert the given number of bytes from the given array, from the given start position, into a long, using the bytes as the least significant part of the long. By the time this is called, the arguments have been checked for validity.

protected FromBytes ( byte value, int startIndex, int bytesToConvert ) : long
value	byte	The bytes to convert
startIndex	int	The index of the first byte to convert
bytesToConvert	int	The number of bytes to use in the conversion
Résultat	long

GetBytes() public méthode

Converts the given signed rational number to an array of bytes.

public GetBytes ( Rational value ) : byte[]
value	Rational	/// The containing the numerator and denominator. ///
Résultat	byte[]

GetBytes() public méthode

Converts the given unsigned rational number to an array of bytes.

public GetBytes ( Rational value ) : byte[]
value	Rational	/// The containing the numerator and denominator. ///
Résultat	byte[]

GetBytes() public méthode

Converts the given ascii string to an array of bytes without adding a null terminator.

public GetBytes ( string value ) : byte[]
value	string	The string to convert.
Résultat	byte[]

GetBytes() public méthode

Converts the given ascii string to an array of bytes optionally adding a null terminator.

public GetBytes ( string value, bool addnull ) : byte[]
value	string	The string to convert
addnull	bool	Whether to add a null terminator to the end of the string.
Résultat	byte[]

IsLittleEndian() public méthode

Indicates the byte order ("endianness") in which data is converted using this class.

Different computer architectures store data using different byte orders. "Big-endian" means the most significant byte is on the left end of a word. "Little-endian" means the most significant byte is on the right end of a word.

public IsLittleEndian ( ) : bool
Résultat	bool
