I am writing a JavaCompletionProposalComputer for the Dali project that
will help the user when typing in the settings for the various JPA annotations
(e.g. provide a list of all the database table names that could be used for
an entity's @Table.name annotation element). I have a few questions:
1. In the org.eclipse.jdt.ui.javaCompletionProposalComputer extension point,
what is the 'categoryId'?
2. Also in the org.eclipse.jdt.ui.javaCompletionProposalComputer extension point,
what is a 'partition'?
3. In org.eclipse.jdt.ui.text.java.IJavaCompletionProposalComputer , what is
supposed to be returned by computeContextInformation(...)?
4. Where would I find the answers to the above questions, before bothering
this forum?
Thanks.

Where is this "category" defined? How would I know about this?

I see these are "defined" in IJavaPartitions; are these "partitions" the
part of a Java source file from which a computer is invoked? For example,
if I have only the "__java_string" partition defined, my computer would
only be invoked when the user requested assistance when the cursor is
inside of a Java String literal. Is that correct? Are these partitions
mutually exclusive? Or do they overlap? For example, does "__java_partitioning"
include all the other "__java_*" partitions?

Ahh, I see now. I'm guessing I would not need this unless I were to insert
a partially completed string and I wanted to prompt the user to type in
some more stuff to complete the string. Is that correct?

I guess my biggest barrier to following how JDT uses this stuff is my
inability to figure out how to get Eclipse to search the JDT source zips
for strings. Do you have any idea how I can go about doing that? A "File
Search" seems to search only my own source files when I tell it to search
the "Workspace"....
Thanks again.

You define this in your extension (plugin.xml).

Not a prompt. Just the hints displayed on top of the method.
