Examples with ArtifactTransformer org.apache.felix.fileinstall.ArtifactTransformer used on opensource projects

Example 1 with ArtifactTransformer

use of org.apache.felix.fileinstall.ArtifactTransformer in project felix by apache.

the class DirectoryWatcher method install.

/**
 * Install an artifact and return the bundle object.
 * It uses {@link Artifact#getPath()} as location
 * of the new bundle. Before installing a file,
 * it sees if the file has been identified as a bad file in
 * earlier run. If yes, then it compares to see if the file has changed
 * since then. It installs the file if the file has changed.
 * If the file has not been identified as a bad file in earlier run,
 * then it always installs it.
 *
 * @param artifact the artifact to be installed
 * @return Bundle object that was installed
