Detailed description

[static] QCryptographicHash_Algorithm Md4

Description: Enum constant QCryptographicHash::Md4

[static] QCryptographicHash_Algorithm Md5

Description: Enum constant QCryptographicHash::Md5

[static] QCryptographicHash_Algorithm Sha1

Description: Enum constant QCryptographicHash::Sha1

void addData(string data,int length)

Description: Method void QCryptographicHash::addData(const char *data, int length)

void addData(string data)

Description: Method void QCryptographicHash::addData(const QByteArray &data)

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

[static] string hash(string data,const QCryptographicHash_Algorithm method)

Description: Static method QByteArray QCryptographicHash::hash(const QByteArray &data, QCryptographicHash::Algorithm method)

This method is static and can be called without an instance.

[const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

[static] new QCryptographicHash new(const QCryptographicHash_Algorithm method)

Description: Constructor QCryptographicHash::QCryptographicHash(QCryptographicHash::Algorithm method)

This method creates an object of class QCryptographicHash.

void reset

Description: Method void QCryptographicHash::reset()

[const] string result

Description: Method QByteArray QCryptographicHash::result()
