Method Detail

getMOMapDiff

public static ConnectionsMergeDiffDetails getMOMapDiff(ConnectionsMergeDiffDetails moInitial,
                                                       ConnectionsMergeDiffDetails moToCompare)

Returns a data structure ConnectionsMergeDiffDetails after computing the delta between the branchpoint MO and the MainlineMO or SandBoxTipMO

Parameters:

moInitial - - MO to comapre against

moToCompare - - MO to be compared

Returns:

data structure ConnectionsMergeDiffDetails containing the delta changes for all connections in a doc

getCandidateMergeConflicts

public static java.util.Map<java.lang.String,ConnectionsMergeDiffDetails> getCandidateMergeConflicts(ConnectionsMergeDiffDetails MLDiff,
                                                                                                     ConnectionsMergeDiffDetails SBDiff)

Returns a Map containg the connectionname(name+classname) and the conflict details for that connection after computing the delta between the MainlineMO and SandboxTipMO

Parameters:

MLDiff - - Mainline delta

SBDiff - - Sandbox delta

Returns:

- Map where the key is connectionname(name+classname) and the value is the delta of MainlineMO and SandboxTipMO

conflictMerge

public static boolean conflictMerge(org.w3c.dom.Document document,
                                    java.lang.String conflictKey,
                                    ReferenceDetails conflictConnection)
                             throws java.lang.Exception

Resolves the hard conflict cases that may exist between Mainline and Sandbox tip. The hard conflicts cases are the real conflict where the handler needs to decide whether to keep the sandbox changes or the mainline changes.

Parameters:

document - - The document to be updated. It will be the Sandbox document retrieved from SandboxMO

conflictKey - - The connectionname(name+classname) for which the conflict needs to be resolved.

conflictConnection - - The refernece node content, that will be used to update the Sandbox document. This is obtained from mainline document.

Returns:

true/false - A true value indicates that the merge was successfull and a false indicating it was unsuccessfull.

Throws:

java.lang.Exception - - In case of an exception to indicate the caller that the merge was not successfull so that the mergestatus can be set accordingly.

autoMerge

public static boolean autoMerge(org.w3c.dom.Document document,
                                java.lang.String nonConflictKey,
                                ReferenceDetails conflictConnection,
                                ConnectionsMergeDiffDetails conflicts)
                         throws java.lang.Exception

Resolves the soft conflict cases(automerge) that may exist between Mainline and Sandbox tip. This will be cases where there has been changes in mainline and sanbox for different connectionname(name+classname)s.The outcome should be to retain both the changes. So the mainline content will be copied over to sandbox and the sandbox content if changes will be retained as is.

Parameters:

document - - The document to be updated. It will be the Sandbox document retrieved from SandboxMO

nonConflictKey - - The changed connectionname(name+classname) from mainline and sandbox , but sandbox keys are not processed as nothing to do in case of sandbox changes and retained as is.

conflictConnection - - The changed reference content from both mainline and sandbox, but sandbox content is not processed.

conflicts - - The conflict details which contains the delta and other details like conflict type, MO origin etc.

Returns:

true/false - A true value indicates that the automerge was successfull and a false indicating it was unsuccessfull.

Throws:

java.lang.Exception - - In case of an exception to indicate the caller that the merge was not successfull so that the mergestatus can be set accordingly.

logObjectMergeDetails

public static void logObjectMergeDetails(java.lang.String key,
                                         ConnectionsMergeDiffDetails conflicts,
                                         int mode,
                                         oracle.mds.core.MetadataObject mainlineMO,
                                         ReferenceDetails SBPreMergeConnection)

Generates a report consisting of conflict/non-conflict changes done by the merge handler.

Parameters:

key - - connectionname(name+classname) to report

conflicts - - The conflict details which contains the delta and other details like conflict type, MO origin etc for a connectionname(name+classname)

mode - - The resolver mode set on the ResourceBundleMergeResolver(default being main wins).

mainlineMO - - Mainline MO

SBPreMergeConnection - - Pre merge content of the sandbox MO to report the pre-refresh sandbox content.
