Interface ChecksumAlgorithmFactorySelector

All Known Implementing Classes:

Component performing selection of ChecksumAlgorithmFactory based on known factory names. Note: this component is NOT meant to be implemented or extended by client, is exposed ONLY to make clients able to get ChecksumAlgorithmFactory instances.
This interface is not intended to be extended by clients.
This interface is not intended to be implemented by clients.
  • Method Details

    • select

      Returns factory for given algorithm name, or throws if algorithm not supported.
      IllegalArgumentException - if asked algorithm name is not supported.
    • selectList

      Returns a list of factories in same order as algorithm names are ordered, or throws if any of the algorithm name is not supported. The returned list has equal count of elements as passed in collection of names, and if names contains duplicated elements, the returned list of algorithms will have duplicates as well.
      IllegalArgumentException - if any asked algorithm name is not supported.
      NullPointerException - if passed in list of names is null.
    • getChecksumAlgorithmFactories

      Returns immutable collection of all supported algorithms. This set represents ALL the algorithms supported by Resolver, and is NOT in any relation to given repository layout used checksums, returned by method RepositoryLayout.getChecksumAlgorithmFactories() (in fact, is super set of it).
    • isChecksumExtension

      boolean isChecksumExtension(String extension)
      Returns true if passed in extension matches any known checksum extension. The extension string may start or contain dot ("."), but does not have to. In former case "ends with" is checked (i.e. "jar.sha1" -> true; ".sha1" -> true) while in latter equality (i.e. "sha1" -> true).
