|
|
|

|
|
wxCountingOutputStream is a specialized output stream which does not write any data anyway,
|
||
|
|
instead it counts how many bytes would get written if this were a normal stream. This
|
||
|
|
can sometimes be useful or required if some data gets serialized to a stream or compressed
|
||
|
|
by using stream compression and thus the final size of the stream cannot be known other
|
||
|
|
than pretending to write the stream. One case where the resulting size would have to be
|
||
|
|
known is if the data has to be written to a piece of memory and the memory has to be
|
||
|
|
allocated before writing to it (which is probably always the case when writing to a
|
||
|
|
memory stream).
