Detailed Description

This memory resource conditionally allocates memory.

It is constructed with a function that determines which upstream resource to use.

This resource can be used to construct complex conditional allocation schemes.

Constructor & Destructor Documentation

choice_memory_resource()

vecmem::choice_memory_resource::choice_memory_resource

(

std::function< memory_resource &(std::size_t, std::size_t)>

decision

)

Construct the choice memory resource.

Parameters

[in]	upstreams	The upstream memory resources to use.
[in]	decision	The function which picks the upstream memory resource to use by index.

Member Function Documentation

do_is_equal()

bool vecmem::details::memory_resource_base::do_is_equal ( const memory_resource &  other ) const

protectedvirtualnoexceptinherited

Compare the equality of *this memory resource with another.

Parameters

other

The other memory resource to compare with

Returns

true if the two memory resources are equal, false otherwise

Reimplemented in vecmem::identity_memory_resource, vecmem::host_memory_resource, and vecmem::terminal_memory_resource.
