Detailed Description

This QosPolicy specifies the value of the ownership strength of a DataWriter used to determine the ownership of an instance.

Attributes

Value	Meaning	Concerns	RxO	Changeable
A long: value	Specifies the value of the "strength" used to arbitrate among multiple DataWriter objects that attempt to modify the same instance of a data-object(identified by Topic + key). This policy only applies if the OWNERSHIP QoS policy is of kind EXCLUSIVE. The default value of the ownership_strength is zero.	DataWriter	N/A	Yes

This QoS policy should be used in combination with the OWNERSHIP policy. It only applies to the situation case where OWNERSHIP kind is set to EXCLUSIVE. The value of the OWNERSHIP_STRENGTH is used to determine the ownership of a data-instance (identified by the key). The arbitration is performed by the DataReader.

Member Function Documentation

operator!=()

template<typename D >

bool dds::core::Value< D >::operator!= ( const Value< D > &  other ) const

inherited

Compare this Value with another Value

Parameters

other

Value

Returns

true if not equal

Definition at line 99 of file Value.hpp.

operator->() [1/2]

template<typename D >

D * dds::core::Value< D >::operator-> ( )

inherited

The operator->() is provided to be able to directly invoke functions on the delegate.

The decision to provide direct access to the delegate was motivated by the need for providing a way that was not invasive with respect to the CXXDDS API and yet would allow for vendor-specific extension. Thus vendor-specific extensions can be invoked on the Value and on all its subclasses as follows:

my_dds_value.standard_function();
my_dds_value->vendor_specific_extension();

Returns

a reference to delegate.
