Member Function Documentation

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

pure virtual

Get the current reference count.

Implemented in agg_util::RCObject.

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

pure virtual

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 virtual

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 virtual

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 virtual

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If it goes from 1 to 0, delete this and this is no longer valid.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