Member Function Documentation

bytes_size()

std::size_t objectstore::Blob::bytes_size ( ) const

virtual

the size of the marshalled representation of this object.

useful when allocating arrays in which to store this object.

NOTE: it is recommended that users not call this directly, and prefer to use mutils::bytes_size(T,v) instead.

Implements mutils::ByteRepresentable.

ensure_registered()

post_object()

void objectstore::Blob::post_object ( const std::function< void(char const *const, std::size_t)> &  ) const

virtual

Pass a pointer to a buffer containing this class's marshalled representation into the function f.

This pointer is not guaranteed to live beyond the duration of the call to f, so make a copy if you need to keep it around.

NOTE: it is recommended that users not call this directly, and prefer to use mutils::post_object(f,T) instead.

Implements mutils::ByteRepresentable.

Definition at line 71 of file Object.cpp.

to_bytes()

std::size_t objectstore::Blob::to_bytes ( char *  v ) const

virtual

Write this class's marshalled representation into the array found at v.

assume v has at least bytes_size() of free memory available; behavior is undefined otherwise.

Returns number of bytes written, which should be the same as bytes_size().

NOTE: it is recommended that users not call this directly, and prefer to use mutils::to_bytes(T,v) instead.

Implements mutils::ByteRepresentable.
