Interface ChecksumGenerator

@ProviderType
public interface ChecksumGenerator

Utility that generates checksums for JCR paths. The checksum is calculated using a depth first traversal and calculates an aggregate checksum on the nodes with the specified node types (via ChecksumGeneratorOptions).

Method Summary

Modifier and Type	Method and Description
Map<String,String>	generateChecksums(javax.jcr.Session session, String path) Convenience method for generateChecksums(session, path, new DefaultChecksumGeneratorOptions()).
Map<String,String>	generateChecksums(javax.jcr.Session session, String path, ChecksumGeneratorOptions options) Traverses the content tree whose root is defined by the path param, respecting the ChecksumGeneratorOptions.

Method Detail

generateChecksums

Map<String,String> generateChecksums(javax.jcr.Session session,
                                     String path)
                              throws javax.jcr.RepositoryException,
                                     IOException

Convenience method for generateChecksums(session, path, new DefaultChecksumGeneratorOptions()).

Parameters:

session - the session

path - the root path to generate checksums for

Returns:

the map of abs path ~> checksums

Throws:

javax.jcr.RepositoryException

IOException

generateChecksums

Map<String,String> generateChecksums(javax.jcr.Session session,
                                     String path,
                                     ChecksumGeneratorOptions options)
                              throws javax.jcr.RepositoryException,
                                     IOException

Traverses the content tree whose root is defined by the path param, respecting the ChecksumGeneratorOptions. Generates map of checksum hashes in the format [ ABSOLUTE PATH ] : [ CHECKSUM OF NODE SYSTEM ]

Parameters:

session - the session

path - the root path to generate checksums for

options - the ChecksumGeneratorOptions that define the checksum generation

Returns:

the map of abs path ~> checksums

Throws:

javax.jcr.RepositoryException

IOException
