Interface GeneratorContextExt

All Superinterfaces:

GeneratorContext

All Known Implementing Classes:

GeneratorContextExtWrapper

public interface GeneratorContextExt
extends GeneratorContext

EXPERIMENTAL and subject to change. Do not use this in production code.

An extension to GeneratorContext which includes access to previously cached rebind results.

TODO(jbrosenberg): Merge this into GeneratorContext directly, once the api has stabilized and we can remove the "experimental" moniker.

getCachedGeneratorResult

com.google.gwt.dev.javac.rebind.CachedRebindResult getCachedGeneratorResult()

Get cached result from a previous run of the current generator, if available.

Returns:

A CachedRebindResult object, if one has been provided to the context. Null is returned if there is no previous result, or if generator result caching is not enabled.

getSourceLastModifiedTime

long getSourceLastModifiedTime(JClassType sourceType)

Get source last modified time.

TODO(jbrosenberg): Implement in terms of a getVersion method yet to be added to TypeOracle, instead of looking for age of a java source file. This will soon be removed.

isGeneratorResultCachingEnabled

boolean isGeneratorResultCachingEnabled()

Check whether generator result caching is currently enabled.

isProdMode

boolean isProdMode()

Returns true if generators are being run to produce code for a production compile. Returns false for dev mode. Generators can use this information to produce code optimized for the target.

reuseTypeFromCacheIfAvailable

boolean reuseTypeFromCacheIfAvailable(java.lang.String typeName)

Mark a type to be reused from the generator result cache. Calling this method with a successful response indicates that the calling generator will not re-generate this type. A cached version of this type will be added to the context once the calling generator returns from GeneratorExt.generateIncrementally(com.google.gwt.core.ext.TreeLogger, com.google.gwt.core.ext.GeneratorContextExt, java.lang.String), with a result containing RebindStatus.USE_PARTIAL_CACHED.

Parameters:

typeName - the fully qualified name of a type.

Returns:

true if the requested type is available from the generator result cache, false otherwise.
