Changed, Enhanced, or Newly Deprecated Features |
| |
|
| |
- 'naming.IName' is now derived from 'binding.IComponentKey', so names and |
| |
addresses must now support the 'findComponent()' method. All PEAK name and |
| |
address types provide support for this. |
| |
|
| |
- The 'lookup()' method of 'binding.IComponentKey' is now called |
| |
'findComponent()', to better distinguish it from 'lookup()' in |
| |
'naming.IBasicContext', which does something very different. |
| |
|
| |
- 'binding.bindTo()' and 'binding.bindSequence()' now pre-adapt their |
| |
arguments to 'IComponentKey', to speed lookups at runtime, and to ensure |
| |
that errors due to an unusable parameter type occur at class creation time |
| |
instead of waiting until lookup time. |
| |
|
| |
- The following 'binding' forms are now deprecated, and will go away before |
| |
0.5 beta is released: |
| |
|
| |
'bindToProperty(x,y)' -- use 'bindTo(PropertyName(x),default=y)' |
| |
|
| |
'bindToParent()' -- use 'bindTo("..")' |
| |
|
| |
'bindToSelf()' -- use 'bindTo(".")' |
| |
|
| |
'bindToUtilities()' -- no replacement; let me know if you're using this. |
| |
|
| |
- There's a new 'peak.storage.files' module, with handy classes like |
| |
'EditableFile'. 'EditableFile' is a class that lets you edit the contents |
| |
of a file "in place", with atomic replacement of the original at transaction |
| |
commit. If the transaction is aborted, the original file is left unchanged. |
