## Member Function Documentation

### QSslError::QSslError(const QSslError &other)

Constructs an identical copy of other.

### QSslError::QSslError(SslError error, const QSslCertificate &certificate)

Constructs a QSslError object. The two arguments specify the error that occurred, and which certificate the error relates to.

See also QSslCertificate.

### QSslError::QSslError(SslError error)

Constructs a QSslError object. The argument specifies the error that occurred.

### QSslError::QSslError()

Constructs a QSslError object with no error and default certificate.

### QSslError &QSslError::operator=(const QSslError &other)

Assigns the contents of other to this error.

This function was introduced in Qt 4.4.

### QSslError::~QSslError()

Destroys the QSslError object.

### QSslCertificate QSslError::certificate() const

Returns the certificate associated with this error, or a null certificate if the error does not relate to any certificate.

See also error() and errorString().

### SslError QSslError::error() const

Returns the type of the error.

See also errorString() and certificate().

### QString QSslError::errorString() const

Returns a short localized human-readable description of the error.

See also error() and certificate().

### void QSslError::swap(QSslError &other)

Swaps this error instance with other. This function is very fast and never fails.

This function was introduced in Qt 5.0.

### bool QSslError::operator!=(const QSslError &other) const

Returns `true` if this error is not equal to other; otherwise returns false.

This function was introduced in Qt 4.4.

### bool QSslError::operator==(const QSslError &other) const

Returns `true` if this error is equal to other; otherwise returns `false`.

This function was introduced in Qt 4.4.
