virtual |
returns the minimum number of bytes that can be written with the next call to write().
The DcmObject write methods rely on avail to return a value > 0 if there is no I/O suspension since certain data such as tag and length are only written "en bloc", i.e. all or nothing.
Implements DcmConsumer.
|
virtual |
closes the file associated with this object.
Updates the internal status variable in case of an error.
|
virtual |
instructs the consumer to flush its internal content until either the consumer becomes "flushed" or I/O suspension occurs.
After a call to flush(), a call to write() will produce undefined behaviour.
Implements DcmConsumer.
|
virtual |
returns the status of the consumer.
Unless the status is good, the consumer will not permit any operation.
Implements DcmConsumer.
|
virtual |
returns true if the consumer is flushed, i.e.
has no more data pending in it's internal state that needs to be flushed before the stream is closed.
Implements DcmConsumer.
|
virtual |
returns the status of the consumer as an OFCondition object.
Unless the status is good, the consumer will not permit any operation.
Implements DcmConsumer.
|
virtual |
processes as many bytes as possible from the given input block.
| buf | pointer to memory block, must not be NULL |
| buflen | length of memory block |
Implements DcmConsumer.
|

reference the file we actually writing to.
Points to file_container_ in most, but not all cases
