@Shardable @LinkerOrder(value=POST) public class PrecompressLinker extends AbstractLinker
A linker that precompresses the public artifacts that it sees. That way, a web server that uses gzip transfer encoding can use the precompressed files instead of having to compress them on the fly.
To use this linker, add the following to your module definition:
<inherits name="com.google.gwt.precompress.Precompress"/>
The files to precompress are specified by the configuration property
precompress.path.regexes. By default, the uncompressed artifacts
are left in the artifact set. If the configuration property
precompress.leave.originals is set to false,
however, then the uncompressed version is removed.

Linker
This method is invoked for linkers annotated with Shardable. It is
called at two points during compilation: after the compile of each
permutation, and after all compilation has finished. The
onePermutation is true for a per-permutation call
and false for a global final-link call.
For one-permutation calls, this method is passed all artifacts generated for just the one permutation. For the global call at the end of compilation, this method sees artifacts for the whole compilation, but with two modifications intended to support builds on computer clusters:
Transferable have been discarded.
