Detailed description

[static,const] new QHostInfo_HostInfoError ptr HostNotFound

Description: Enum constant QHostInfo::HostNotFound

[static,const] new QHostInfo_HostInfoError ptr NoError

Description: Enum constant QHostInfo::NoError

[static,const] new QHostInfo_HostInfoError ptr UnknownError

Description: Enum constant QHostInfo::UnknownError

void _assign(const QHostInfo other)

Description: Assigns another object to self

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 destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, 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.

[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.

void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

[static] void abortHostLookup(int lookupId)

Description: Static method void QHostInfo::abortHostLookup(int lookupId)

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

[const] QHostAddress[] addresses

Description: Method QList<QHostAddress> QHostInfo::addresses()

Python specific notes:

The object exposes a readable attribute 'addresses'. This is the getter.

void addresses=(QHostAddress[] addresses)

Description: Method void QHostInfo::setAddresses(const QList<QHostAddress> &addresses)

Python specific notes:

The object exposes a writable attribute 'addresses'. This is the setter.

QHostInfo assign(const QHostInfo d)

Description: Method QHostInfo &QHostInfo::operator=(const QHostInfo &d)

void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

void destroy

Description: Explicitly destroys the object

Use of this method is deprecated. Use _destroy instead

[const] bool destroyed?

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

Use of this method is deprecated. Use _destroyed? instead

[const] new QHostInfo ptr dup

Description: Creates a copy of self

[const] QHostInfo_HostInfoError error

Description: Method QHostInfo::HostInfoError QHostInfo::error()

Python specific notes:

The object exposes a readable attribute 'error'. This is the getter.

void error=(const QHostInfo_HostInfoError error)

Description: Method void QHostInfo::setError(QHostInfo::HostInfoError error)

Python specific notes:

The object exposes a writable attribute 'error'. This is the setter.

[const] string errorString

Description: Method QString QHostInfo::errorString()

Python specific notes:

The object exposes a readable attribute 'errorString'. This is the getter.

void errorString=(string errorString)

Description: Method void QHostInfo::setErrorString(const QString &errorString)

Python specific notes:

The object exposes a writable attribute 'errorString'. This is the setter.

[static] QHostInfo fromName(string name)

Description: Static method QHostInfo QHostInfo::fromName(const QString &name)

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

[const] string hostName

Description: Method QString QHostInfo::hostName()

Python specific notes:

The object exposes a readable attribute 'hostName'. This is the getter.

void hostName=(string name)

Description: Method void QHostInfo::setHostName(const QString &name)

Python specific notes:

The object exposes a writable attribute 'hostName'. This is the setter.

[const] bool is_const_object?

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

Use of this method is deprecated. Use _is_const_object? instead

Description: Static method QString QHostInfo::localDomainName()

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

[static] string localHostName

Description: Static method QString QHostInfo::localHostName()
