All Known Implementing Classes:

AbstractContentGenerator
```
public interface ContentGenerator
```
Interface to support dynamic content generation. This was originally intended for generating metadata files when they aren't present on remote repositories. However, it's designed to accommodate all sorts of dynamic content.

Method Detail

generateFileContent

org.commonjava.maven.galley.model.Transfer generateFileContent(org.commonjava.indy.model.core.ArtifactStore store,
                                                               String path,
                                                               org.commonjava.maven.galley.event.EventMetadata eventMetadata)
                                                        throws IndyWorkflowException

Generate dynamic content in the event it's not found in the ArtifactStore. This is secondary to the main content retrieval logic, as a last effort to avoid returning a missing result.

Throws:: IndyWorkflowException

generateDirectoryContent

List<StoreResource> generateDirectoryContent(org.commonjava.indy.model.core.ArtifactStore store,
                                             String path,
                                             List<StoreResource> existing,
                                             org.commonjava.maven.galley.event.EventMetadata eventMetadata)
                                      throws IndyWorkflowException

Generate resources for any missing files that this generator can create. This is meant to contribute to an existing directory listing, so the existing resources are given in order to allow the generator to determine whether a new resources is warranted.

Throws:: IndyWorkflowException

generateGroupFileContent

org.commonjava.maven.galley.model.Transfer generateGroupFileContent(org.commonjava.indy.model.core.Group group,
                                                                    List<org.commonjava.indy.model.core.ArtifactStore> members,
                                                                    String path,
                                                                    org.commonjava.maven.galley.event.EventMetadata eventMetadata)
                                                             throws IndyWorkflowException

Generate dynamic content for a group. This is the PRIMARY form of group access, with secondary action being to attempt normal retrieval from one of the member stores.

Throws:: IndyWorkflowException

generateGroupDirectoryContent

List<StoreResource> generateGroupDirectoryContent(org.commonjava.indy.model.core.Group group,
                                                  List<org.commonjava.indy.model.core.ArtifactStore> members,
                                                  String path,
                                                  org.commonjava.maven.galley.event.EventMetadata eventMetadata)
                                           throws IndyWorkflowException

Generate resources for merged group files that this generator can create.

Throws:: IndyWorkflowException

handleContentStorage

void handleContentStorage(org.commonjava.indy.model.core.ArtifactStore store,
                          String path,
                          org.commonjava.maven.galley.model.Transfer result,
                          org.commonjava.maven.galley.event.EventMetadata eventMetadata)
                   throws IndyWorkflowException

Tidy up any generated content associated with the stored file

Throws:: IndyWorkflowException

handleContentDeletion

void handleContentDeletion(org.commonjava.indy.model.core.ArtifactStore store,
                           String path,
                           org.commonjava.maven.galley.event.EventMetadata eventMetadata)
                    throws IndyWorkflowException

Tidy up any generated content associated with the deleted file

Throws:: IndyWorkflowException

canProcess
```
boolean canProcess(String path)
```
