* @class AliHLTComponent
* Base class of HLT data processing components.
* framework will allocate a buffer of appropriate size and call the processing
* again.
*
+ * @subsection alihltcomponent-error-codes Data processing
+ * For return codes, the following scheme applies:
+ * - The data processing methods have to indicate error conditions by a negative
+ * error/return code. Preferably the system error codes are used like
+ * e.g. -EINVAL. This requires to include the header
+ * <pre>
+ * \#include \<cerrno\>
+ * </pre>
+ * - If no suitable input block could be found (e.g. no clusters for the TPC cluster
+ * finder) set size to 0, block list is empty, return 0
+ * - If no ususable or significant signal could be found in the input blocks
+ * return an empty output block, set size accordingly, and return 0. An empty output
+ * block here could be either a real empty one of size 0 (in which case size also
+ * would have to be set to zero) or a block filled with just the minimum necessary
+ * accounting/meta-structures. E.g. in the TPC
+ *
