Enable/disable system output cache
bool Application :: cacheOutput ( bool bCache )
In order to suppress output messages and collecting those in a output cache, true should be passed in bCache. In order to re-activate system output, false has to be passed. When reactivating system output, the output cache will be cleared. In order to obtain output cache content, outputCache() may be called before.
Cached output is not written automatically to application output area, but has to be written explicitly.
cacheOutput(true);
... do something and collect messages
output(outputCache(); // write output
cacheOutput(false);
