Typedef Documentation

◆ exponential_size_array_policy

template<template< typename > class SegmentType = pmem::obj::vector>

using pmem::obj::exponential_size_array_policy = typedef segment_vector_internal::exponential_size_policy< segment_vector_internal::array_64, SegmentType>

Exponential size policy with pmemobj array of size 64 as a type of segment vector, so this is a static array of segments and each segment is of SegmentType.

requires more memory than exponential_size_vector_policy
is faster and more efficient than exponential_size_vector_policy

◆ exponential_size_vector_policy

template<template< typename > class SegmentType = pmem::obj::vector>

using pmem::obj::exponential_size_vector_policy = typedef segment_vector_internal::exponential_size_policy<pmem::obj::vector, SegmentType>

Exponential size policy with pmemobj vector as a type of segment vector, so this is a dynamic vector of segments and each segment is of SegmentType.

requires less memory than exponential_size_array_policy
is slower and less efficient than exponential_size_array_policy

◆ fixed_size_vector_policy

template<size_t SegmentSize = 1024, template< typename > class SegmentType = pmem::obj::vector>

using pmem::obj::fixed_size_vector_policy = typedef segment_vector_internal::fixed_size_policy<pmem::obj::vector, SegmentType, SegmentSize>

Fixed size policy with pmemobj vector of a given size as a type of segment vector, so this is a dynamic vector of segments and each segment is of SegmentType.

is slower than the exponential one (because it has more segments)
causes less fragmentation than the exponential one

◆ transaction

using pmem::obj::transaction = typedef basic_transaction

By default, pmem::obj::transaction is an alias to pmem::obj::basic_transaction.

To change it to pmem::obj::flat_transaction define LIBPMEMOBJ_CPP_USE_FLAT_TRANSACTION macro.

To see what is the difference between the two please look at the examples for flat tx:

#include <libpmemobj++/make_persistent.hpp>

         *  |-----------|
         *  | ptr1 ctor |
         *  |-----------|
         *  |  A ctor   |
         *
         * Since ptr2 is a pointer to some huge array of elements,
         * calling ptr2 ctor will most likely result in make_persistent
         * throwing an exception (due to out of memory). This exception
         * will, in turn, cause stack unwinding - already constructed
         * elements must be destroyed (in this example ptr1 destructor
         * will be called).
         *
         * If we'd use basic_transaction the allocation failure, apart
         * from throwing an exception, would also cause the transaction
         * to abort (by default, in basic_transaction, all transactional
         * functions failures cause tx abort). This is problematic since
         * the ptr1 destructor, which is called during stack unwinding,
         * expects the transaction to be in WORK stage (and the actual
         * stage is ABORTED). As a result the application will fail on
         * assert (and probably crash in NDEBUG mode).
         *
         * Now, consider what will happen if we'd use flat_transaction
         * instead. In this case, make_persistent failure will not abort
         * the transaction, it will only result in an exception. This
         * means that the transaction is still in WORK stage during
         * stack unwinding. Only after it completes, the transaction is
         * aborted (it's happening at the outermost level, when exiting
         * create_a lambda).

         * constructor MUST be a flat_transaction. This is because
         * flat_transaction does not abort immediately when catching an
         * exception. Instead it passes it to the outermost transaction
         * - the abort is performed at that outermost level. In case of
         * a basic_transaction the abort would be done within the B ctor

Exceptions

transaction_scope_error	if called outside of an active transaction
transaction_free_error	on transactional free failure.

Transactionally free an object of type T held in a persistent_ptr.

This function can be used to transactionally free an object. Calls the object's destructor before freeing memory. Cannot be used for array types.

To ensure that proper recovery is possible, ptr should be set to null after delete_persistent call and within the same transaction.

Parameters

Exceptions

transaction_scope_error	if called outside of an active transaction
transaction_free_error	on transactional free failure.
