Examples of com.google.gwt.dev.MinimalRebuildCache

com.google.gwt.dev.MinimalRebuildCache
MinimalRebuildCache contains compiler information that can be persisted between compiles to decrease compilation time.
Cached information is specific to a single permutation and it is the responsibility of the framework driving the Compiler to supply the right Cache instance for the right Module configuration and to make sure that the Compiler is only processing one permutation at a time.
All type names referenced here are assumed to be binary names.
A "typeName" here might be a root type or nested type but a "compilationUnitName" here will always be the name of just the root type in a compilation unit.


    CompilerOptions runOptions = new CompilerOptionsImpl(compileDir, newModuleName, options);
    compilerContext = compilerContextBuilder.options(runOptions).build();


    // Looks up the matching rebuild cache using the final set of overridden binding properties.
    MinimalRebuildCache knownGoodMinimalRebuildCache =
        getKnownGoodMinimalRebuildCache(bindingProperties);
    job.setCompileStrategy(knownGoodMinimalRebuildCache.isPopulated() ? CompileStrategy.INCREMENTAL
        : CompileStrategy.FULL);


    // Takes care to transactionally replace the saved cache only after a successful compile.
    MinimalRebuildCache mutableMinimalRebuildCache = new MinimalRebuildCache();
    mutableMinimalRebuildCache.copyFrom(knownGoodMinimalRebuildCache);
    boolean success =
