public class SingleScriptLinker
- extends com.google.gwt.core.ext.linker.impl.SelectionScriptLinker
A Linker for producing a single JavaScript file from a GWT module. The use of
this Linker requires that the module has exactly one distinct compilation
result.

- Returns a human-readable String describing the Linker.

- 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:
- All EmittedArtifacts have been converted to BinaryEmittedArtifacts
- All artifacts not marked as
Transferable
have been discarded.
- Overrides:
link
in class com.google.gwt.core.ext.linker.impl.SelectionScriptLinker
- Parameters:
logger
- the TreeLogger to record tocontext
- provides access to the Linker's environmentartifacts
- an unmodifiable view of the artifacts to linkonePermutation
- 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
