Public Member Functions | |
object | __reduce__ () |
object | __reduce_persist__ (object pickler) |
VectorUchar | encodeToBamStream () |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object. | |
bool | encodeToBamStream (VectorUchar data, BamWriter writer) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. | |
fillin (DatagramIterator scan, BamReader manager) | |
This internal function is intended to be called by each class's make_from_bam() method to read in all of the relevant data from the BamFile for the new object. | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. | |
![]() | |
TypeHandle | getType () |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. | |

VectorUchar encodeToBamStream | ( | ) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object.
Returns an empty bytes object on failure.
This is a convenience method particularly useful for cases when you are only serializing a single object. If you have many objects to process, it is more efficient to use the same BamWriter to serialize all of them together.
bool encodeToBamStream | ( | VectorUchar | data, |
BamWriter | writer ) |
Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string.
Returns true on success, false on failure.

fillin | ( | DatagramIterator | scan, |
BamReader | manager ) |
UpdateSeq getBamModified | ( | ) |
Returns the current bam_modified counter.
This counter is normally incremented automatically whenever the object is modified.
|
static |
markBamModified | ( | ) |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams.
This should normally not need to be called by user code; it should be called internally when the object has been changed in a way that legitimately requires its retransmission to any connected clients.
