  - checkRebindRuleAvailable
```
public boolean checkRebindRuleAvailable(String sourceTypeName)
```
    Description copied from interface: GeneratorContext
    
    Checks whether a rebind rule is available for a given sourceTypeName, such as can appear in a replace-with or generate-with rule.
    
    Specified by:
    
    checkRebindRuleAvailable in interface GeneratorContext
    
    Parameters:
    
    sourceTypeName - the name of a type to check for rebind rule availability.
    
    Returns:
    
    true if a rebind rule is available
  - commit
```
public void commit(TreeLogger logger,
                   PrintWriter pw)
```
    Description copied from interface: GeneratorContext
    
    Commits source generation begun with GeneratorContext.tryCreate(TreeLogger, String, String).
    
    Specified by:
    
    commit in interface GeneratorContext
  - commitArtifact
```
public void commitArtifact(TreeLogger logger,
                           Artifact<?> artifact)
                    throws UnableToCompleteException
```
    Description copied from interface: GeneratorContext
    
    Add an Artifact to the ArtifactSet that will be presented to the Linker chain at the end of the compilation cycle. Custom sub-classes of Artifact can be used to write cooperating Generator and Linker combinations. This method is semantically equivalent to calling ArtifactSet.replace(Artifact) if an equivalent Artifact had previously been committed.
    
    Specified by:
    
    commitArtifact in interface GeneratorContext
    
    Parameters:
    
    logger - a logger; normally the logger passed into the currently invoked generator or a branch thereof
    
    artifact - the Artifact to provide to the Linker chain.
    
    Throws:
    
    UnableToCompleteException
  - commitResource
```
public GeneratedResource commitResource(TreeLogger logger,
                                        OutputStream os)
                                 throws UnableToCompleteException
```
    Description copied from interface: GeneratorContext
    
    Commits resource generation begun with GeneratorContext.tryCreateResource(TreeLogger, String).
    
    Specified by:
    
    commitResource in interface GeneratorContext
    
    Returns:
    
    the GeneratedResource that was created as a result of committing the OutputStream.
    
    Throws:
    
    UnableToCompleteException - if the resource cannot be written to disk, if the specified stream is unknown, or if the stream has already been committed
  - getCachedGeneratorResult
```
public CachedGeneratorResult getCachedGeneratorResult()
```
    Description copied from interface: GeneratorContext
    
    Get the cached rebind result that has been provided to the context, if available. The provided result will be the most recent previously generated result for the currently active rebind rule and requested type name.
    
    Specified by:
    
    getCachedGeneratorResult in interface GeneratorContext
    
    Returns:
    
    A CachedGeneratorResult object, if one has been provided to the context. Null is returned if there is no previous result available.
  - getPropertyOracle
```
public PropertyOracle getPropertyOracle()
```
    Description copied from interface: GeneratorContext
    
    Gets the property oracle for the current generator context. Generators can use the property oracle to query deferred binding properties.
    
    Specified by:
    
    getPropertyOracle in interface GeneratorContext
  - getResourcesOracle
```
public ResourceOracle getResourcesOracle()
```
    Description copied from interface: GeneratorContext
    
    Returns a resource oracle containing all resources that are mapped into the module's source (or super-source) paths. Conceptually, this resource oracle exposes resources which are "siblings" to GWT-compatible Java classes. For example, if the module includes com.google.gwt.core.client as a source package, then a resource at com/google/gwt/core/client/Foo.properties would be exposed by this resource oracle.
    
    Specified by:
    
    getResourcesOracle in interface GeneratorContext
  - getTypeOracle
```
public TypeOracle getTypeOracle()
```
    Description copied from interface: GeneratorContext
    
    Gets the type oracle for the current generator context. Generators can use the type oracle to ask questions about the entire translatable code base.
    
    Specified by:
    
    getTypeOracle in interface GeneratorContext
    
    Returns:
    
    a TypeOracle over all the relevant translatable compilation units in the source path
  - isGeneratorResultCachingEnabled
```
public boolean isGeneratorResultCachingEnabled()
```
    Description copied from interface: GeneratorContext
    
    Check whether generator result caching is currently enabled.
    
    Specified by:
    
    isGeneratorResultCachingEnabled in interface GeneratorContext
  - isProdMode
```
public boolean isProdMode()
```
    Description copied from interface: GeneratorContext
    
    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.
    
    Specified by:
    
    isProdMode in interface GeneratorContext
  - tryCreate
```
public PrintWriter tryCreate(TreeLogger logger,
                             String packageName,
                             String simpleName)
```
    Description copied from interface: GeneratorContext
    
    Attempts to get a PrintWriter so that the caller can generate the source code for the named type. If the named types already exists, null is returned to indicate that no work needs to be done. The file is not committed until GeneratorContext.commit(TreeLogger, PrintWriter) is called.
    
    Specified by:
    
    tryCreate in interface GeneratorContext
    
    Parameters:
    
    logger - a logger; normally the logger passed into the currently invoked generator, or a branch thereof
    
    packageName - the name of the package to which the create type belongs
    
    simpleName - the unqualified source name of the type being generated
    
    Returns:
    
    null if the package and class already exists, otherwise a PrintWriter is returned.
  - tryCreateResource
```
public OutputStream tryCreateResource(TreeLogger logger,
                                      String partialPath)
                               throws UnableToCompleteException
```
    Description copied from interface: GeneratorContext
    
    Attempts to get an OutputStream so that the caller can write file contents into the named file underneath the compilation output directory. The file is not committed until GeneratorContext.commitResource(TreeLogger, OutputStream) is called.
    
    Specified by:
    
    tryCreateResource in interface GeneratorContext
    
    Parameters:
    
    logger - a logger; normally the logger passed into the currently invoked generator, or a branch thereof
    
    partialPath - the name of the file whose contents are to be written; the name can include subdirectories separated by forward slashes ('/')
    
    Returns:
    
    an OutputStream into which file contents can be written, or null if a resource by that name is already pending or already exists
    
    Throws:
    
    UnableToCompleteException - if the resource could not be initialized for some reason, such as if the specified partial path is invalid
  - tryReuseTypeFromCache
```
public boolean tryReuseTypeFromCache(String typeName)
```
    Description copied from interface: GeneratorContext
    
    Mark a type to be reused from the generator result cache, if available. 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 IncrementalGenerator.generateIncrementally(com.google.gwt.core.ext.TreeLogger, com.google.gwt.core.ext.GeneratorContext, java.lang.String), with a result containing RebindMode.USE_PARTIAL_CACHED.
    
    Specified by:
    
    tryReuseTypeFromCache in interface GeneratorContext
    
    Parameters:
    
    typeName - the fully qualified source name of a type.
    
    Returns:
    
    true if the requested type is available from the generator result cache, false otherwise.
