SoByteStream () | |
Constructor and destructor. | |
~SoByteStream () | |
Constructor and destructor. | |
void | convert (SoNode *node, bool binaryFormat=TRUE) |
Convert the passed node, path, or path list into a byte stream. | |
void | convert (SoPath *path, bool binaryFormat=TRUE) |
void | convert (SoPathList *pathList, bool binaryFormat=TRUE) |
These convert the passed scene graph object(s) into a byte stream. | |
void * | getData () |
Returns the data from the last convert() operation. | |
uint32_t | getNumBytes () |
Returns the number of bytes from the last convert() operation. | |
void | copy (void *d, size_t len) |
This allows apps to store raw data here without converting an Inventor node, path, or path list. | |
bool | isRawData () const |
Static Public Member Functions | |
static SoPathList * | unconvert (SoByteStream *byteStream) |
Unconvert a byte stream back to a path list. | |
static SoPathList * | unconvert (void *data, uint32_t numBytes) |
These take byte stream data and unconvert it back to scene graph objects. | |
This class creates a byte stream representation of a scene graph, using an SoWriteAction to write path lists to an in-memory buffer. Byte streams are commonly used to transfer data in copy and paste operations.

Caller may specify whether the byte stream is written in binary (TRUE) or ascii (FALSE) format. The converted data can be accessed through getData() and getNumBytes().

void SoByteStream::convert | ( | SoPathList * | pathList, |
bool | binaryFormat = TRUE ) |
The caller may specify whether the byte stream is written in binary (TRUE) or ASCII (FALSE) format, and can pass the object(s) by node, path, or pathList.
References TRUE.
void SoByteStream::copy | ( | void * | d, |
size_t | len ) |
This sets isRaw to TRUE, and that data cannot be unconverted.

inline |
This byte stream format is well suited to data transfers, like copy and paste.

static |
This static routine performs an SoDB::read on the data, and returns a path list of the paths read in. These take byte stream data and unconvert it back to scene graph objects. The objects are returned in a path list.
