Checksum

An opaque structure representing a checksumming operation. To create a new GChecksum, use Checksum.new. To free a GChecksum, use Checksum.free.

class Checksum {

GChecksum* gChecksum;

protected

bool ownedRef;

GChecksum* getChecksumStruct(bool transferOwnership);

void* getStruct();

this(GChecksum* gChecksum, bool ownedRef);

void getDigest(ubyte[] buffer);

this(GChecksumType checksumType);

Checksum copy();

string getString();

void reset();

void update(char[] data);

static ptrdiff_t typeGetLength(GChecksumType checksumType);

static string computeChecksumForBytes(GChecksumType checksumType, Bytes data);

static string computeChecksumForData(GChecksumType checksumType, char[] data);

static string computeChecksumForString(GChecksumType checksumType, string str, ptrdiff_t length);

}

Constructors

this this(GChecksum* gChecksum, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(GChecksumType checksumType): Creates a new glib.Checksum, using the checksum algorithm checksum_type. If the checksum_type is not known, NULL is returned. A glib.Checksum can be used to compute the checksum, or digest, of an arbitrary binary blob, using different hashing algorithms.

Destructor

A destructor is present on this object, but not explicitly documented in the source.

Members

Functions

copy Checksum copy(): Copies a glib.Checksum If checksum has been closed, by calling Checksum.getString or Checksum.getDigest, the copied checksum will be closed as well.
free void free(): Frees the memory allocated for checksum.
getChecksumStruct GChecksum* getChecksumStruct(bool transferOwnership): Get the main Gtk struct
getDigest void getDigest(ubyte[] buffer): Gets the digest from checksum as a raw binary vector and places it into buffer. The size of the digest depends on the type of checksum.
getString string getString(): Gets the digest as a hexadecimal string.
getStruct void* getStruct(): the main Gtk struct as a void*
reset void reset(): Resets the state of the checksum back to its initial state.
update void update(char[] data): Feeds data into an existing glib.Checksum The checksum must still be open, that is Checksum.getString or Checksum.getDigest must not have been called on checksum.

Static functions

computeChecksumForBytes string computeChecksumForBytes(GChecksumType checksumType, Bytes data): Computes the checksum for a binary data. This is a convenience wrapper for Checksum.new, Checksum.getString and Checksum.free.
computeChecksumForData string computeChecksumForData(GChecksumType checksumType, char[] data): Computes the checksum for a binary data of length. This is a convenience wrapper for Checksum.new, Checksum.getString and Checksum.free.
computeChecksumForString string computeChecksumForString(GChecksumType checksumType, string str, ptrdiff_t length): Computes the checksum of a string.
typeGetLength ptrdiff_t typeGetLength(GChecksumType checksumType): Gets the length in bytes of digests of type checksum_type

Variables
