void prepareToSend()

This class is used for transcribing Inventor data. Transcription is the process of packaging changes to a database and sending them over a "wire" to another database.

The SoTranSender class is used on the sending side of transcription. It packages up changes to a Inventor database into a file or memory area defined by an SoOutput instance. It supports a limited set of changes to a database; each change is stored as a command in the transcription area. The SoTranReceiver class can be used at the other end to interpret the transcribed commands.

SoTranSender(SoOutput *output)

The constructor takes a pointer to an SoOutput instance that determines what the transcription area is (file or memory).

void insert(SoNode *node)

Adds an INSERT command to the transcription area. The given node will be added as the last child of the root node on the receiving end.

void insert(SoNode *node, SoNode *parent, int n)

Adds an INSERT command to the transcription area. The given node will be added as the nth child of the given parent node on the receiving end. A NULL parent node causes the node to be added to the receiving end's root node.

void remove(SoNode *parent, int n)

Adds a REMOVE command to the transcription area. The nth child of the given (non-NULL) parent node on the receiving end will be removed.

void replace(SoNode *parent, int n, SoNode *newNode)

Adds a REPLACE command to the transcription area. The nth child of the given (non-NULL) parent node on the receiving end will be replaced with newNode.

void modify(SoNode *node)

Adds a MODIFY command to the transcription area. Updates the field data for the given node to the new contents. Note that this changes only field data; children of groups are not affected, nor is any non-field instance data.

void prepareToSend()

Prepares a SoTranSender instance for transcription, making sure the transcription area is complete and all packaged to go. This must be called before the transcription can be performed.
