[jdt-core-dev] Field references

["Jerome Lanneluc/SNZ/OTI" <Jerome_Lanneluc@xxxxxxx>]

Right now, you can search for field references in 3 ways:
- IJavaSearchConstants.REFERENCES: all references to a field are reported 
(this does not include field declarations)
- IJavaSearchConstants.READ_REFERENCES: all read references to a field are 
reported (this does not include field declarations, or field 
modifications)
- IJavaSearchConstants.WRITE_REFERENCES: all write references to a field are 
reported (this does not include field declarations - even if the field has 
an initializer)

However, bug 5563: 'Write reference on declaration not reported' made us realize that what you really want in the 3rd case is the field 
modifications (including field initializations). In this case, the 
following implicit rule REFERENCES = READ_REFERENCES +  WRITE_REFERENCES 
is false.

I propose to change the last 2 constants to:
- IJavaSearchConstants.READ_ONLY: all read access to a field are reported 
(this does not include field declarations, or field modifications)
- IJavaSearchConstants.MODIFICATIONS: all field modifications (including 
initializations) to a field are reported.

And the implicit rule disappears because there is no notion of reference 
in this last 2 constants.

The Java Search page would have to be modified accordingly.

Comments are welcome (please respond to jdt-core-dev@xxxxxxxxxxx).
