Constructs a new signature from the Latin-1 string viewed by signature.

### `[explicit]` QDBusSignature::QDBusSignature(const QString &signature)

Constructs a new signature from the given signature.

### `[explicit]` QDBusSignature::QDBusSignature(const char *signature)

Constructs a new signature from the given signature.

### void QDBusSignature::setSignature(const QString &signature)

Assigns the value of the given signature to this signature.

See also signature().

### QString QDBusSignature::signature() const

Returns this signature.

See also setSignature().

### `[noexcept]` void QDBusSignature::swap(QDBusSignature &other)

Swaps this signature with other. This operation is very fast and never fails.
