Method Detail

addNamedObj

public void addNamedObj(NamedObj namedObj)

Add a NamedObject to the ObjectManager. These are searched when getting an object by LSID.

Parameters:

namedObj -

Throws:

java.lang.Exception

removeNamedObj

public NamedObj removeNamedObj(NamedObj namedObj)

Attempt to remove NamedObj from ObjectManager: if getIdFor(namedObj) returns an LSID for an object in the ObjectManager, it will be removed.

Parameters:

namedObj -

Returns:

removed NamedObj, or null if none.

removeNamedObjs

public java.util.ArrayList<NamedObj> removeNamedObjs(NamedObj namedObj)

Attempt to remove NamedObj from ObjectManager: if getIdFor(namedObj) returns an LSID for an object in the ObjectManager, it will be removed.

Parameters:

namedObj -

Returns:

removed NamedObj, or null if none.

removeObject

public NamedObj removeObject(KeplerLSID lsid)
                      throws java.lang.Exception

Attempts to remove object from ObjectManager: if getObjectRevision(lsid) returns a NamedObj, calls removeNamedObj on this NamedObj. NOTE: Chances are good this won't remove the NamedObj you want.

Parameters:

lsid -

Returns:

removed NamedObj, or null if none.

Throws:

java.lang.Exception

removeObjectForLSID

public NamedObj removeObjectForLSID(KeplerLSID lsid)

Parameters:

lsid - for the NamedObj to remove from ObjectManager

Returns:

the NamedObj removed, or null if none.

removeObjectsForLSIDWithoutRevision

public java.util.ArrayList<NamedObj> removeObjectsForLSIDWithoutRevision(java.lang.String lsidWithoutRevision)

Remove all NamedObjects from ObjectManager that match this lsid without revision.

Parameters:

lsidWithoutRevision -

Returns:

ArrayList of NamedObjs that were removed.

getObjectType

public java.lang.String getObjectType(KeplerLSID lsid)
                               throws java.lang.Exception

Parameters:

lsid -

Returns:

Throws:

java.lang.Exception

getObjectRevision

public NamedObj getObjectRevision(KeplerLSID lsid)
                           throws java.lang.Exception

Parameters:

lsid -

Returns:

Throws:

java.lang.Exception

getHighestObjectRevision

public NamedObj getHighestObjectRevision(KeplerLSID lsid)
                                  throws java.lang.Exception

Return the NamedObj that has the highest revision number for a given LSID after searching through all the NamedObjs accessible by the ObjectManager. If no NamedObj is found at all then try to get the highest revision from the cache. If that doesn't find anything then return null. This method will replace the existing getObject(KeplerLSID) method

Parameters:

lsid -

Returns:

Throws:
