## Package org.apache.tools.ant.types.selectors.modifiedselector

Interface Summary
Algorithm: The Algorithm defines how a value for a file is computed.
Cache: A Cache let the user store key-value-pairs in a permanent manner and access them.

Class Summary
ChecksumAlgorithm: Computes a 'checksum' for the content of file using java.util.zip.CRC32 and java.util.zip.Adler32.
DigestAlgorithm: Computes a 'hashvalue' for the content of file using java.security.MessageDigest.
EqualComparator: Simple implementation of Comparator for use in CacheSelector.
HashvalueAlgorithm: Computes a 'hashvalue' for the content of file using String.hashValue().
ModifiedSelector: Selector class that uses Algorithm, Cache and Comparator for its work.
ModifiedSelector.AlgorithmName: The enumerated type for algorithm.
ModifiedSelector.CacheName: The enumerated type for cache.
ModifiedSelector.ComparatorName: The enumerated type for algorithm.
PropertiesfileCache: Use java.util.Properties for storing the values.
