equals

@QtUninvokable public boolean equals(Object other)

Description copied from class: QtObject

Used to check if this object shares native resources with the other object if the other object is a subtype of QtJambiInterface. Otherwise it will return the result of calling the super class implementation.

Overrides:

equals in class QtObject

Parameters:

other - The object with which to compare

Returns:

true if the native resources of the two objects are one and the same.

hashCode

@QtUninvokable public int hashCode()

Overrides:

hashCode in class Object

create

public final Object create()

Overloaded function for create(Object) with copy = null.

Returns:

new instance

create

public final Object create(Object copy)

Returns a copy of copy, assuming it is of the type that this QMetaType instance was created for.

If copy is null, creates a default constructed instance.

See QMetaType::create(int, const void *)

Parameters:

copy -

Returns:

new instance

toString

@QtUninvokable public final String toString()

Returns the type name associated with this QMetaType as String.

Overrides:

toString in class Object

Returns:

type name

fromType

public static QMetaType fromType(Class<?> clazz, QMetaType... instantiations)

Returns the QMetaType corresponding to the given class.

If the class has never been registered as meta type UnknownType is returned.

If given class is generic (e.g. QList, QPair, QMap) specify the template instantiations to be used in the registered template type.

See QMetaMethod::fromType<T>()

Parameters:

clazz - the class to be registered

instantiations - optional instantiations for generics (templates)

Returns:

meta type ID

registerMetaType

public static int registerMetaType(Class<?> clazz, QMetaType... instantiations)

Registers the given class as meta type. Returns the internal ID used by QMetaType.

After a type has been registered, you can create and destroy objects of that type dynamically at run-time.

If given class is generic (e.g. QList, QPair, QMap) specify the template instantiations to be used in the registered template type.

See qRegisterMetaType<T>()

Parameters:

clazz - the class to be registered

instantiations - optional instantiations for generics (templates)

Returns:

meta type ID

metaTypeId

public static int metaTypeId(Class<?> clazz, QMetaType... instantiations)

Returns the meta type id of goven class at compile time.

If the class has never been registered as meta type UnknownType is returned.

If given class is generic (e.g. QList, QPair, QMap) specify the template instantiations to be used in the registered template type.

See qMetaTypeId<T>()

Parameters:

clazz - the class to be registered

instantiations - optional instantiations for generics (templates)

Returns:

meta type ID

javaType

public final Class<?> javaType()

Returns the Java class for this meta type.

Returns:

java class

javaType

public static Class<?> javaType(int metaTypeId)

Returns the Java class for the given meta type ID.

Returns:

java class

fromName

public static QMetaType fromName(String name)

fromName

public static QMetaType fromName(QByteArray name)

fromName

public static QMetaType fromName(byte[] name)

clone

public QMetaType clone()
