Api change

[DerOrfa]

• complete revision of the conversion interface of ValuePtr
  • move compare, copyTo, and copy{To,From}Mem into ValuePtrBase, so they can be used without knowing the current type
  • add ValuePtrBase::convertToId and ValuePtrBase::as which do copy/convert only when needed
  • remove a lot of redundant conversion functions (ValuePtr::convertTo,getScalingTo ..)
• rename all {I,i}d to "ID"
• remove some obsolete restrictions in MemChunk[NonDel] - it can now be created fom raw memory of any (supported) type

So the new interface is:

• if you want a deep copy in any case:
  • use copyTo if you have a ValuePtrBase as target
  • use copyToMem if your target is raw memory
  • use copyFromMem if your source is raw memory
  • use copyAs if you know the targets type and want to create a new ValuePtr of that type
  • use copyByID if you know the targets type ID and want to get a new ValuePtr of that type
• if you want a cheap copy if possible:
  • use as if you know the targets type and want to get a ValuePtr of that type
  • use convertByID if you know the targets type ID and want to get a ValuePtr of that type
• all functions have an optional parameter scale to specify the scaling
  • if its not given, it will be computed automatically
• getRawAddress now returns boost::shared_ptr instead of boost::weak_ptr and it has optional parameter offset

Changes in Chunk:

• all compare functions except compareRange( const size_t source_start[], const size_t source_end[], const Chunk &dst, const size_t destination[] ) has been removed
• a simple compare to compare whole chunks has been added
• copyLine has been removed - use copyRange instead

Lots of changes, indeed! :) Let's say we will solve this on next wednesdays ISIS meeting, so everyone (including lydia of course ;) ) has time to have look at it and find something to complain about..

Some more additions:

• PropertyMap::find to search single keys in the property tree
• the class FilePtr to ease memory mapping

[DerOrfa]

• storage for PropertyMap is two-dimensional now to be able to store lists of properties
  • this is intentionally only available to derived classes
• added basic matrix class to do some matrix-algebra on FixedVector
• added aplying operators *=,/=,+= and -= to FixedVector
• added Selection::set to set selection from id
• added length check to Image::copyToMem to make sure people know what they're doing when copying into raw memory
