Detailed Description

This file provides a Grammar for the type Gaudi::Accumulators::Axis It allows to use that type from python with a format liks : ( nbins, min, max, title ) where title can be ommited.

Create a hash with a large avalanche effect from 32 or 64 bit integers or a string.

General Gaudi namepace.

General Gaudi namespace.

Helper functions to set/get the application return code.

Header file for std:chrono::duration-based Counters.

note that for the parsing, min and max will be parsed as doubles before being converted to the actual type used as Arithmetic for Axis, so an automatic conversion between the 2 must be provided

Include this header file (instead of GaudiKernel/Counters.h) if you want to use std::chrono::duration-based Counters. It includes support for the required arithmetic and stream operations.

note: the constants below are not arbitrary, but are picked carefully such that the bit shuffling has a large 'avalanche' effect... Code by Brett Mulvey (old link: http://bretm.home.comcast.net/~bretm/hash/)

note: as a result, you might call this a quasi-random (not to be confused with psuedo-random!) number generator, in that it generates an output which satisfies a requirement on the uniformity of its output distribution. (and not on the predictability of the next number in the sequence, based on knowledge of the preceding numbers)

note: another way to look at this is is as an (approximation of an) evaporating black hole: whatever you dump in to it, you get something uniformly distributed back ;-)

hash-function: heeded for boost::hash

Attention

NEVER use the actual hash value for anything stored in files, as it is not guaranteed that the hashing scheme will remain the same. The only reason for this function is Python and transparent usage of this object for hashmap-like containers

Gaudi::Hash

Returns

the actual hash value

range() [1/2]

Range_< CONTAINER > Gaudi::range ( const CONTAINER & cnt )

inline

simple function to create the range from the arbitrary container

const CONTAINER& cnt = ... ;
 
Range_<CONTAINER> r = range ( cnt ) ;

The range could be created over ALL container types which supports at least the bidirectional iterators.

The minimum requirements from the container type:

• support the concept of "CONTAINER::value_type"
• support the concept of "CONTAINER::const_iterator"
• support the concept of "CONTAINER::const_reference"
• support the concept of "CONTAINER::const_reverse_iterator"
• the iterator should be ok for "std::distance" and "std::advance"
• support for "const_iterator CONTAINER::begin () const"
• support for "const_iterator CONTAINER::end () const"
• support for "const_reverse_iterator CONTAINER::rbegin () const"
• support for "const_reverse_iterator CONTAINER::rend () const"

setAppReturnCode()

StatusCode Gaudi::setAppReturnCode ( SmartIF< IProperty > & appmgr, int value, bool force = false )

inline

Set the application return code.

By default the return code of the application is modified only if the original value was 0 (i.e. no error). In this way we keep the first cause of error.

Parameters

appmgr	IProperty interface of the ApplicationMgr
value	value to assign to the return code
force	if set to true, the return code is set even if it was already set

Returns

SUCCESS if it was possible to set the return code or the return code was already set
