Serial

Serial – Container for nsp serialized object
serialize – serialize an nsp object

Calling sequence

S = serialize(Obj);
A = serialize(Obj,’m’)

Parameters

Obj: any nsp objects.
S: a Serial object
A: a numeric matrix.

Description
The Serial data type is useful to serialize any nsp object in order for example to transmit it through communication networks as an array of characters. For example, it can be used with pvm or mpi to transmit any nsp object. The function serialize is used to produce a serialized object. For some applications it can be useful to hide the serialized object in a numerical matrix, this can be done with the extra argument ’m’. Note that an object serialized in a numeric matrix can be corrupted if the matrix is changed. Thus this version, which is mainly used in scicos which transmit block parameters through int or double array, should be used with care.

methods

O=S.unserialize[] unserialize S. unserialize can also be used as a function for Serial arguments or for numeric argument.

Examples

function y=f(x);y=sin(x);endfunction; 
L = list(1,2,"c",%f, %t, rand(2,1), f); 
S = serialize(L); 
L1=unserialize(S); 
A = serialize(L,'m'); 
L1=unserialize(A); 
ok = exec('unserialize(rand(1,10))',errcatch=%t);
