equals

@QtUninvokable
public boolean equals(Object other)

Description copied from class: QtObject

Used to check if this object shares the same native counterpart with the other object, i.e. the objects are equals if their native counterparts are identical. Qt value types override this method to make a value comparison. Otherwise it will return the result of calling the super class implementation.

Overrides:

equals in class QtObject

Parameters:

other - other object

Returns:

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

hashCode

@QtUninvokable
public int hashCode()

Overrides:

hashCode in class Object

toString

@QtUninvokable
public final String toString()

Returns the type name associated with this QMetaType as String.

Overrides:

toString in class Object

Returns:

type name

registerMetaType

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

Deprecated.

Use qRegisterMetaType(Class, QMetaType...) instead.

metaTypeId

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

Deprecated.

Use qMetaTypeId(Class, QMetaType...) instead.

registerDataStreamOperators

public static <T> int registerDataStreamOperators(QMetaType.DataStreamInFn<T> datastreamInFn,
 QMetaType.DataStreamOutFn<T> datastreamOutFn)

Registers datastream operators for meta type T.

Parameters:

datastreamInFn - (only lambda expressions allowed)

datastreamOutFn - (only lambda expressions allowed)

Returns:

the registered meta type

registerDebugStreamOperator

public static <T> int registerDebugStreamOperator(QMetaType.DebugStreamFn<T> debugstreamFn)

Registers debug stream operator for meta type T.

Parameters:

debugstreamFn - (only lambda expressions allowed)

Returns:

the registered meta type

registerConverter

public static <T1,
T2> boolean registerConverter(QMetaType.ConverterFn<T1,T2> converterFn)

Registers debug stream operator for meta type T.

Parameters:
