Detailed Description

This memory resource tries to allocate with several upstream resources and returns the first succesful one.

Constructor & Destructor Documentation

coalescing_memory_resource()

vecmem::coalescing_memory_resource::coalescing_memory_resource

(

std::vector< std::reference_wrapper< memory_resource > > &&

upstreams

)

Constructs the coalescing memory resource.

Note

The memory resources passed to this constructed are given in order of decreasing priority. That is to say, the first one is tried first, then the second, etc.

Parameters

[in]

upstreams

The upstream memory resources to use.

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.
