Detailed Description

Group one or more functions in an instance of a CallChain, then call them in sequence using CallChain::call().

Used mostly by the interrupt chaining code, but can be used for other purposes.

Deprecated:: Do not use this class. This class is not part of the public API of mbed-os and is being removed in the future.

Note: Synchronization level: Not protected

Example:

#include "mbed.h"
CallChain chain;
void first(void) {
    printf("'first' function.\n");
}
void second(void) {
    printf("'second' function.\n");
}
class Test {
public:
    void f(void) {
        printf("A::f (class member).\n");
    }
};
int main() {
    Test test;
    chain.add(second);
    chain.add_front(first);
    chain.add(&test, &Test::f);
    chain.call();
}

CallChain ( int size = 4 )

Create an empty chain.

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

Parameters

size	(optional) Initial size of the chain

virtual ~CallChain ( )

virtual

Create an empty chain.

Member Function Documentation

pFunctionPointer_t add ( Callback< void()> func )

Add a function at the end of the chain.

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

Parameters

func	A pointer to a void function

Returns: The function object created for 'func'

pFunctionPointer_t add	(	T *	obj,
		M	method
	)

Add a function at the end of the chain.

Parameters

obj	pointer to the object to call the member function on
method	pointer to the member function to be called

Returns: The function object created for 'obj' and 'method'

Deprecated:: The add function does not support cv-qualifiers. Replaced by add(callback(obj, method)).

Definition at line 127 of file CallChain.h.

pFunctionPointer_t add_front ( Callback< void()> func )

Add a function at the beginning of the chain.

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

Parameters

func	A pointer to a void function

Returns: The function object created for 'func'

pFunctionPointer_t add_front	(	T *	obj,
		M	method
	)

Add a function at the beginning of the chain.

Parameters

obj	pointer to the object to call the member function on
method	pointer to the member function to be called

Returns: The function object created for the object and method pointers

Deprecated:: The add_front function does not support cv-qualifiers. Replaced by add_front(callback(obj, method)).

Definition at line 162 of file CallChain.h.

void call ( )

Call all the functions in the chain in sequence.

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

void clear ( )

Clear the call chain (remove all functions in the chain).

Deprecated:: Do not use this function. This class is not part of the public API of mbed-os and is being removed in the future.

int find ( pFunctionPointer_t f ) const

Look for a function object in the call chain.

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

Parameters

f	the function object to search

Returns: The index of the function object if found, -1 otherwise.

pFunctionPointer_t get ( int i ) const

Get a function object from the chain.

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

Parameters

i	function object index

Returns: The function object at position 'i' in the chain

void operator() ( void )

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

Definition at line 238 of file CallChain.h.

Definition at line 250 of file CallChain.h.

bool remove ( pFunctionPointer_t f )

Remove a function object from the chain.

Deprecated:: Do not use this function, this class is not part of the public API of mbed-os and is being removed in the future.

f the function object to remove

Returns: true if the function object was found and removed, false otherwise.

int size ( ) const
