Detailed Description

A logical chunk of data representing serialized data.

Currently, just a wrapper for a vector of bytes, which is not efficient in terms of memory copying. This will change in the future as will the API.

Member Function Documentation

◆ as()

template<typename T >
const T * esi::MessageData::as ( ) const
inline

Cast to a type.

Throws if the size of the data does not match the size of the message. The lifetime of the resulting pointer is tied to the lifetime of this object.

◆ empty()

bool esi::MessageData::empty ( ) const
inline

Returns true if this message contains no data.

Definition at line 131 of file Common.h.

◆ from()

template<typename T >
static MessageData esi::MessageData::from ( T &  t)
inlinestatic

Cast from a type to its raw bytes.
