Short example sentences

Also, less importantly, reference counting requires every memory-managed object to reserve space for a reference count. (17 words)

In this context, the simple reference count of an object is the in-degree of its vertex. (17 words)

It can also help increase concurrency by avoiding many threads locking a reference count to increase it. (17 words)

Longer example sentences

It ignores these references, only counting references in data structures, but before an object with reference count zero can be deleted, the system must verify with a scan of the stack and registers that no other reference to it still exists. (41 words)

A smart pointer can be passed by reference to a function, which avoids the need to copy-construct a new smart pointer (which would increase the reference count on entry into the function and decrease it on exit). (38 words)

Another technique devised by Henry Baker involves deferred increments, citation in which references which are stored in local variables do not immediately increment the corresponding reference count, but instead defer this until it is necessary. (35 words)

Example sentences (18)

An object's reference count is incremented when a reference to it is created, and decremented when a reference is destroyed.

The count may be stored adjacent to the object's memory or in a side table somewhere else, but in either case, every single reference-counted object requires additional storage for its reference count.

This allows reference count 1 strings to be mutated directly whilst higher reference count strings are copied before mutation.

Also, less importantly, reference counting requires every memory-managed object to reserve space for a reference count.

A smart pointer can be passed by reference to a function, which avoids the need to copy-construct a new smart pointer (which would increase the reference count on entry into the function and decrease it on exit).

If a reference-counting garbage collection algorithm is implemented, then each of these garbage components must contain at least one cycle; otherwise, they would have been collected as soon as their reference count (i.

It ignores these references, only counting references in data structures, but before an object with reference count zero can be deleted, the system must verify with a scan of the stack and registers that no other reference to it still exists.

The Deutsch-Bobrow method of reference counting capitalizes on the fact that most reference count updates are in fact generated by references stored in local variables.

Another technique devised by Henry Baker involves deferred increments, citation in which references which are stored in local variables do not immediately increment the corresponding reference count, but instead defer this until it is necessary.

Because the total weight does not change, the object's reference count does not need to be updated.

If an object reliably has a pointer at a certain location, the reference count can be stored in the unused bits of the pointer.

In fact, two of the three methods that all COM objects must provide (in the IUnknown interface) increment or decrement the reference count.

In this context, the simple reference count of an object is the in-degree of its vertex.

It can also help increase concurrency by avoiding many threads locking a reference count to increase it.

It is based on the observation that a cycle can only be isolated when a reference count is decremented to a nonzero value.

It is possible to avoid this issue by delegating the freeing of objects whose reference count dropped to zero to other threads, at the cost of extra overhead.

Memory space with the size of an unsigned pointer is commonly used for this task, meaning that 32 or 64 bits of reference count storage must be allocated for each object.

Operations that would replace a value with a modified copy are generally optimized to instead modify the original when its reference count indicates it to be unshared.
