Go to the top directory and do this:
cp dev-tools/eclipse/dot.project .project
cp dev-tools/eclipse/dot.classpath .classpath
cp -r dev-tools/eclipse/dot.settings .settings

The 'ant eclipse' target does this setup.

You need to use an IDE. Find the Attribute type and show all subclasses.
This shows a lot of rare ones and a few which are used a lot. Now, look at
source code for various TokenFilters and search for other uses of the
Attributes you find. This generally is how I figured it out.

Also, after the full Analyzer stack is called, the caller saves the output
(I guess to codecs?). You can look at which Attributes it saves.

  hi Shen
May be you can see some source code in org.apache.lucene.analysis
package,
such LowerCaseFilter.java,**StopFilter.java and so on.

and some common attribute includes:

offsetAtt = addAttribute(OffsetAttribute.**class);
termAtt = addAttribute(**CharTermAttribute.class);
typeAtt = addAttribute(TypeAttribute.**class);

Regards

  Hello!
The simplest way is to look at Lucene javadoc and see what
implementations of Attribute interface there are -

  http://lucene.apache.org/core/**4_0_0/core/org/apache/lucene/**
util/Attribute.html<http://lucene.apache.org/core/4_0_0/core/org/apache/lucene/util/Attribute.html>

  thanks, i read this ready. it is useful, but it is too 'small'...
e.g. for this.charTermAttr = addAttribute(**CharTermAttribute.class);
i want to know what are the other attributes i need in order to

implement
my function. where i can find a references to these attributes? i tried
on

lucene & solr wiki, but all i found is a list of the names of these
attributes, nothing about what are they capable of...

  Hi,
I need a guide to implement my own TokenFilter. I checked the wiki,

but I
could not find any useful guide :(
