This function is declared non-inline to work around a compiler bug in g++ 2.96. |
An ordered list of data elements, formatted in memory for transmission over a socket or writing to a data file.
Data elements should be added one at a time, in order, to the Datagram. The nature and contents of the data elements are totally up to the user. When a Datagram has been transmitted and received, its data elements may be extracted using a DatagramIterator; it is up to the caller to know the correct type of each data element in order.
A Datagram is itself headerless; it is simply a collection of data elements.

static void Datagram::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.

void Datagram::set_array | ( | PTA_uchar | data | ) | [inline] |
Replaces the data in the Datagram with the data in the indicated PTA_uchar.
This is assignment by reference: subsequent changes to the Datagram will also change the source PTA_uchar.
Definition at line 443 of file datagram.I.
void Datagram::set_stdfloat_double | ( | bool | stdfloat_double | ) | [inline] |
Changes the stdfloat_double flag, which defines the operation performed by add_stdfloat() and DatagramIterator::get_stdfloat().
When this is true, add_stdfloat() adds a 64-bit floating-point number; when it is false, it adds a 32-bit floating-point number. The default is based on the STDFLOAT_DOUBLE compilation flag.
