virtual const libdap::DDS* agg_util::DDSAccessInterface::getDDS ( ) const

pure virtualinherited

Accessor for a contained DDS.

The returned object is to be considered an alias, and should NOT be deleted or stored outside the lifetime of this! If the object doesn't have a valid DDS currently, NULL is returned.

Returns: alias to the DDS that the object is containing, or NULL if none.

Implemented in ncml_module::NetcdfElement.

Referenced by agg_util::AggMemberDatasetDDSWrapper::getDataDDS(), and agg_util::AggMemberDatasetSharedDDSWrapper::getDataDDS().

virtual int agg_util::RCObjectInterface::getRefCount ( ) const

pure virtualinherited

Get the current reference count.

Implemented in agg_util::RCObject.

virtual int agg_util::RCObjectInterface::ref ( ) const

pure virtualinherited

Increase the reference count by one.

const since we do not consider the ref count part of the semantic constness of the rep

Implemented in agg_util::RCObject.

Referenced by agg_util::AggMemberDatasetSharedDDSWrapper::AggMemberDatasetSharedDDSWrapper().

virtual void agg_util::RCObjectInterface::removeFromPool ( ) const

pure virtualinherited

If the object is in an auto-delete pool, remove it from the pool and force it to only delete when it's ref count goes to 0.

Useful when we desire a particular object stay around outside of the pool's lifetime.

Implemented in agg_util::RCObject.

virtual std::string agg_util::RCObjectInterface::toString ( ) const

pure virtualinherited

Returns: a string with the refcount and memory address

Implemented in agg_util::RCObject, ncml_module::NCMLElement, ncml_module::AggregationElement, ncml_module::NetcdfElement, ncml_module::VariableElement, ncml_module::DimensionElement, ncml_module::ScanElement, ncml_module::AttributeElement, ncml_module::ValuesElement, ncml_module::VariableAggElement, ncml_module::ExplicitElement, ncml_module::ReadMetadataElement, and ncml_module::RemoveElement.

virtual int agg_util::RCObjectInterface::unref	(	)	const
throw	(
	)

pure virtualinherited

Decrease the reference count by one.

If it goes from 1 to 0, delete this and this is no longer valid.

Returns: the new ref count. If it is 0, the called knows the object was deleted.

It is illegal to unref() an object with a count of 0. We don't throw to allow use in dtors, so the caller is to not do it!

const since the reference count is not part of the semantic constness of the rep

Implemented in agg_util::RCObject.
