Detailed Description

Adheres to the C++17 std::pmr::monotonic_buffer_resource specification except that it does not provide default upstream constructors and therefore has no dependencies to types defined in cetl/pf17/sys/memory_resource.hpp.

Member Function Documentation

do_allocate()

void * cetl::pf17::pmr::deviant::basic_monotonic_buffer_resource::do_allocate ( std::size_t size_bytes, std::size_t alignment )

inlineoverrideprotectedvirtual

Template method to implement in terms of cetl::pf17::pmr::memory_resource::allocate.

Parameters

size_bytes	See cetl::pf17::pmr::memory_resource::allocate.
alignment	See cetl::pf17::pmr::memory_resource::allocate.

Returns

See cetl::pf17::pmr::memory_resource::allocate.

Exceptions

See	cetl::pf17::pmr::memory_resource::allocate.

Implements cetl::pf17::pmr::memory_resource.

References std::max(), cetl::pf17::pmr::memory_resource::max_size(), and std::min().

do_deallocate()

void cetl::pf17::pmr::deviant::basic_monotonic_buffer_resource::do_deallocate ( void * p, std::size_t size_bytes, std::size_t alignment )

inlineoverrideprotectedvirtual

Template method to implement in terms of cetl::pf17::pmr::memory_resource::deallocate.

Parameters

p	See cetl::pf17::pmr::memory_resource::deallocate.
size_bytes	See cetl::pf17::pmr::memory_resource::deallocate.
alignment	See cetl::pf17::pmr::memory_resource::deallocate.

Exceptions

See	cetl::pf17::pmr::memory_resource::deallocate.

Implements cetl::pf17::pmr::memory_resource.

do_is_equal()

bool cetl::pf17::pmr::deviant::basic_monotonic_buffer_resource::do_is_equal ( const memory_resource & rhs ) const

inlineoverrideprotectedvirtualnoexcept

Template method to implement in terms of cetl::pf17::pmr::memory_resource::is_equal.

Parameters

rhs	See cetl::pf17::pmr::memory_resource::is_equal.

Returns

See cetl::pf17::pmr::memory_resource::is_equal

Implements cetl::pf17::pmr::memory_resource.

References cetl::pf17::pmr::memory_resource::memory_resource().

do_max_size()

std::size_t cetl::pf17::pmr::deviant::basic_monotonic_buffer_resource::do_max_size ( ) const

inlineoverrideprotectedvirtualnoexcept

Default implementation of cetl::pf17::pmr::memory_resource::max_size that simply returns std::numeric_limits<std::size_t>::max().

Implementations can override this method and do not need to call the base class.

Returns

See cetl::pf17::pmr::memory_resource::max_size.

Reimplemented from cetl::pf17::pmr::memory_resource.

References std::numeric_limits::max(), and cetl::pf17::pmr::deviant::memory_resource_traits< T >::max_size().
