Method Detail

getTargets

java.util.List<java.lang.String> getTargets()

The targets (normally URLs) for downloading the artifact. These should be tried in-order until one works.

getFilename

java.lang.String getFilename()

The name of the artifact. The caller is free to use this name, or not. But using this name gives consistency particularly between brooklyn local-repos and brooklyn install directories.

getUnpackedDirectoryName

java.lang.String getUnpackedDirectoryName(java.lang.String defaultVal)

The name of the directory in the expanded artifact (e.g. if it's a tar.gz file then the name of the directory within it). If no value is known, the defaultVal will be returned. This can return null if the artifact is not an archive (and if defaultVal is null). TODO The driver needs to know what will happen when an install archive is unpacked (e.g. an AS7 install tgz may be automatically expanded into a directory named "jboss-as-7.1.1-FINAL"). However, it's unclear where the best place to encode that is. The driver supplying the default seems sensible.
