## com.google.gwt.core.linker
Class D8ScriptLinker

    java.lang.Object
      com.google.gwt.core.ext.Linker
          com.google.gwt.core.ext.linker.AbstractLinker
              com.google.gwt.core.ext.linker.impl.SelectionScriptLinker

    @LinkerOrder(value=PRIMARY)
    @Shardable
    public class D8ScriptLinker

extends com.google.gwt.core.ext.linker.impl.SelectionScriptLinker

A Linker for producing a single JavaScript file from a GWT module that can be run in the d8 command line profiler. The use of this Linker requires that the module has exactly one distinct compilation result.

Note: This linker is considered experimental and is likely going to have breaking changes in future.
