static TypeHandle | getClassType () |
A specific kind of Datagram, especially for sending across or receiving from a network.
It's different only in that it knows which Connection and/or NetAddress it is to be sent to or was received from.
NetDatagram | ( | ) |
Constructs an empty datagram.
NetDatagram | ( | Datagram const | copy | ) |
NetDatagram | ( | NetDatagram const | copy | ) |
addBeFloat32 | ( | float | value | ) | [inherited] |
Adds a 32-bit single-precision big-endian floating-point number to the datagram.
Since this kind of float is not necessarily portable across different architectures, special care is required.
addBeFloat64 | ( | double | value | ) | [inherited] |
Adds a 64-bit big-endian floating-point number to the datagram.
addBeInt16 | ( | short int | value | ) | [inherited] |
Adds a signed 16-bit big-endian integer to the datagram.
addBeInt32 | ( | int | value | ) | [inherited] |
Adds a signed 32-bit big-endian integer to the datagram.
addBeInt64 | ( | long int | value | ) | [inherited] |
Adds a signed 64-bit big-endian integer to the datagram.
addBeUint16 | ( | unsigned short int | value | ) | [inherited] |

addFixedString | ( | string | str, |
unsigned int | size | ||

Adds a fixed-length string to the datagram.
If the string given is less than the requested size, this will pad the string out with zeroes; if it is greater than the requested size, this will silently truncate the string.
