Method Detail

### getDescription

    public java.lang.String getDescription()

  Description copied from class: `Linker`
  Returns a human-readable String describing the Linker.

  Specified by:
    `getDescription` in class `Linker`

### link

    public ArtifactSet link(TreeLogger logger,
                            LinkerContext context,
                            ArtifactSet artifacts,
                            boolean onePermutation)
                     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
