private void lock()

unlock

private void unlock()

getProjectGAVs

public java.util.Set<GAV> getProjectGAVs()

Description copied from interface: TychoRepositoryIndex

Receive the set of GAVs contained in this index

Specified by:

getProjectGAVs in interface TychoRepositoryIndex

Returns:

an unmodifiable defensive copy of the GAV set contained in this index

addGav

public void addGav(GAV gav)

Description copied from interface: TychoRepositoryIndex

Adds a GAV to the index

Specified by:

addGav in interface TychoRepositoryIndex

Parameters:

gav - not null

removeGav

public void removeGav(GAV gav)

Description copied from interface: TychoRepositoryIndex

Remove a GAV from the index.

Specified by:

removeGav in interface TychoRepositoryIndex

save

public void save()
          throws java.io.IOException

Description copied from interface: TychoRepositoryIndex

Changes performed via TychoRepositoryIndex.addGav(GAV) , TychoRepositoryIndex.removeGav(GAV) will only be reflected in the memory state of the index.

Specified by:

save in interface TychoRepositoryIndex

Throws:

java.io.IOException
