                 throws UnableToCompleteException
Description copied from class: 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:

  1. All EmittedArtifacts have been converted to BinaryEmittedArtifacts
  2. All artifacts not marked as Transferable have been discarded.

Overrides:
link in class Linker
Parameters:
logger - the TreeLogger to record to
context - provides access to the Linker's environment
artifacts - an unmodifiable view of the artifacts to link
onePermutation - true for a one-permutation call
Returns:
the artifacts that should be propagated through the linker chain
Throws:
UnableToCompleteException - if compilation violates assumptions made by the Linker or for errors encountered by the Linker
