Method Detail

getChildRepoFile

public RepoFile getChildRepoFile(RepoFile parent,
                        String name)

Get the child of the given parent with the specified name.

Parameters:

parent - the parent of the queried child.

name - the name of the queried child.

Returns:

the child matching the given criteria; null, if there is no such object in the database.

getRepoFile

public RepoFile getRepoFile(File localRoot,
                   File file)
                     throws IllegalArgumentException

Get the RepoFile for the given file in the file system.

Parameters:

localRoot - the repository's root directory in the file system. Must not be null.

file - the file in the file system for which to query the associated RepoFile. Must not be null.

Returns:

the RepoFile for the given file in the file system; null, if no such object exists in the database.

Throws:

IllegalArgumentException - if one of the parameters is null or if the given file is not located inside the repository - i.e. it is not a direct or indirect child of the given localRoot.

getLocalRootDirectory

public Directory getLocalRootDirectory()

getChildRepoFiles

public Collection<RepoFile> getChildRepoFiles(RepoFile parent)

Get the children of the given parent.

The children are those RepoFiles whose parent equals the given parent parameter.

Parameters:

parent - the parent whose children are to be queried. This may be null, but since there is only one single instance with RepoFile.parent being null - the root directory - this is usually never null.

Returns:

the children of the given parent. Never null, but maybe empty.

getRepoFilesChangedAfterExclLastSyncFromRepositoryId

public Collection<RepoFile> getRepoFilesChangedAfterExclLastSyncFromRepositoryId(long localRevision,
                                                                        UUID exclLastSyncFromRepositoryId)

Get those RepoFiles whose localRevision is greater than the given localRevision.

Parameters:

localRevision - the localRevision, after which the files to be queried where modified.

exclLastSyncFromRepositoryId - the lastSyncFromRepositoryId to exclude from the result set. This is used to prevent changes originating from a repository to be synced back to its origin (unnecessary and maybe causing a collision there). See issue 25.

Returns:

those RepoFiles which were modified after the given localRevision. Never null, but maybe empty.

deletePersistent

public void deletePersistent(RepoFile entity)

Overrides:
