Callback functions

The LambdaPointer class is used to provide contextfull callback functions, using c++11 lambdas

template <typename Out, typename... In>
template<>
class packetio::LambdaPointer<Out(In...)>

A wrapper for storing a pointer to a lambda function, that works with captured variables.

Template Parameters

• Out: lambda return type
• In: lambda argument types

Public Functions

LambdaPointer(Out (*fptr)(In...))

Create a LambdaPointer from a raw function pointer.

Parameters

• fptr: The context-less function

template <typename T>
LambdaPointer(T *lambda)

Create a LambdaPointer from a lambda, possibly with captures.

Parameters

• lambda: A pointer to the lambda function. Because this a pointer, this must be allocated on the stack.

Out operator()(In... in)

Invoke the underlying function.

operator bool()

Determine if the reference has been initialized.

Mirror of the Arduino interface

These classes, found in _compat, allow testing on the desktop, and potentially execution on non-Arduino platforms

class Print

Lightweight mirror of the (undocumented) arduino Print class, for use on other platforms.

Subclassed by packetio::PacketPrint, Stream

Public Functions

virtual size_t write(uint8_t) = 0

size_t write(const char *str)

virtual size_t write(const uint8_t *buffer, size_t size) = 0

size_t write(const char *buffer, size_t size)

class Stream : Print

Lightweight mirror of the arduino Stream class, for use on other platforms.

Subclassed by packetio::PacketStream

Public Functions

virtual int available() = 0

virtual int read() = 0

virtual int peek() = 0

virtual void flush() = 0

Stream()

size_t readBytes(char *buffer, size_t length)

size_t readBytes(uint8_t *buffer, size_t length)
