Detailed description

[const] void assign(const QMetaType other)

Description: Assign the contents of another object to self

This method assigns the contents of another object to self. This is a deep copy that does not only copy the reference but the actual content.

[static] void * construct(int type)

Description: Static method void * QMetaType::construct(int type, const void *copy)

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

[static] void * construct(int type,void * copy)

Description: Static method void * QMetaType::construct(int type, const void *copy)

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

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.

[const] QMetaType dup

Description: Creates a copy of self

[static] bool isRegistered(int type)

Description: Static method bool QMetaType::isRegistered(int type)

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

[static] bool isRegistered?(int type)

Description: Static method bool QMetaType::isRegistered(int type)

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] bool load(QDataStream stream,int type,void * data)

Description: Static method bool QMetaType::load(QDataStream &stream, int type, void *data)

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

[static] new QMetaType new

Description: Constructor QMetaType::QMetaType()

This method creates an object of class QMetaType.

[static] void qt_destroy(int type,void * data)

Description: Static method void QMetaType::destroy(int type, void *data)

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

[static] bool save(QDataStream stream,int type,void * data)

Description: Static method bool QMetaType::save(QDataStream &stream, int type, const void *data)

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

[static] int type(string typeName)

Description: Static method int QMetaType::type(const char *typeName)

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

[static] string typeName(int type)

Description: Static method const char * QMetaType::typeName(int type)

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

[static] void unregisterType(string typeName)

Description: Static method void QMetaType::unregisterType(const char *typeName)

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