VectorUchar | encodeToBamStream () |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object. More... | |
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. More... | |
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. More... | |
UpdateSeq | getBamModified () |
Returns the current bam_modified counter. More... | |
markBamModified () | |
Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More... | |
![]() | |
TypeHandle | getType () |
int | getTypeIndex () |
Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. More... | |
bool | isExactType (TypeHandle handle) |
Returns true if the current object is the indicated type exactly. More... | |
bool | isOfType (TypeHandle handle) |
Returns true if the current object is or derives from the indicated type. More... | |
![]() | |
int | getRefCount () |
Returns the current reference count. More... | |
ref () | |
Explicitly increments the reference count. More... | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. More... | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. More... | |
bool | unref () |
Explicitly decrements the reference count. More... | |
![]() | |
TypeHandle | type |
Returns the TypeHandle representing this object's type. More... | |
![]() | |
int | ref_count |
The current reference count. More... | |
A base class for things which need to inherit from both TypedWritable and from ReferenceCount.
It's convenient to define this intermediate base class instead of multiply inheriting from the two classes each time they are needed, so that we can sensibly pass around pointers to things which are both TypedWritables and ReferenceCounters.
See also TypedObject for detailed instructions.

Reads the bytes created by a previous call to encode_to_bam_stream(), and extracts and returns the single object on those bytes.
Returns NULL on error.
This method is intended to replace decode_raw_from_bam_stream() when you know the stream in question returns an object of type TypedWritableReferenceCount, allowing for easier reference count management. Note that the caller is still responsible for maintaining the reference count on the return value.
