bool TypedWritable::decode_raw_from_bam_stream | ( | TypedWritable *& | ptr, |
ReferenceCount *& | ref_ptr, | ||
const string & | data, | ||
BamReader * | reader = NULL |
||
) | [static, inherited] |
Reads the string created by a previous call to encode_to_bam_stream(), and extracts the single object on that string.
Returns true on success, false on on error.
This variant sets the TypedWritable and ReferenceCount pointers separately; both are pointers to the same object. The reference count is not incremented; it is the caller's responsibility to manage the reference count.
Note that this method cannot be used to retrieve objects that do not inherit from ReferenceCount, because these objects cannot persist beyond the lifetime of the BamReader that reads them. To retrieve these objects from a bam stream, you must construct a BamReader directly.
If you happen to know that the particular object in question inherits from TypedWritableReferenceCount or PandaNode, consider calling the variant of decode_from_bam_stream() defined for those methods, which presents a simpler interface.

string TypedWritable::encode_to_bam_stream | ( | ) | const [inline, inherited] |
Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a string string.
Returns empty string 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.
