Member Function Documentation

createGhostAnchors()

int createGhostAnchors ( const DataExecution::ObjectArray &  anchorDifferences, DataExecution::Workspace &  workspace, ComparisonRole  desc  ) const

protected

Parameters

anchorDifferences	Array of differences between anchors in a pair of workspaces in two different workflows.
workspace	The workspace onto which to add anchors that do not exist.
desc	The workflow descriptor indicating whether workspace is taking the role of workflow A or workflow B in the comparison

Returns

The number of anchors created.

createGhostConnections()

int createGhostConnections ( const DataExecution::ObjectArray &  operationDifferences, DataExecution::Workspace &  workspace  ) const

protected

Parameters

operationDifferences	Array of differences between a set of operations in two different workflows.
workspace	The workspace containing some of the operations referenced in the differences array.

Returns

The number of connections created.

createGhostInputs()

int createGhostInputs ( const DataExecution::ObjectArray &  inputDifferences, DataExecution::Operation &  operation, ComparisonRole  desc  ) const

protected

Parameters

inputDifferences	Array of differences between inputs in two different workflows.
operation	The operation onto which to add inputs that do not exist.
desc	The workflow descriptor indicating whether workspace is taking the role of workflow A or workflow B in the comparison

Returns

The number of inputs created.

createGhostNotes()

int createGhostNotes ( const DataExecution::ObjectArray &  noteDifferences, DataExecution::Workspace &  workspace, ComparisonRole  desc  ) const

protected

Parameters

noteDifferences	Array of differences between notes in a pair of workspaces in two different workflows.
workspace	The workspace into which to add notes that do not exist.
desc	The workflow descriptor indicating whether workspace is taking the role of workflow A or workflow B in the comparison

Returns

The number of notes created.

createGhostOperation()

DataExecution::Operation & createGhostOperation ( const DataExecution::Operation &  altOp, DataExecution::Workspace &  workspace  ) const

protected

Parameters

altOp	The original operation (which exists in the alternate workflow) for which a ghost operation is required in workspace.
workspace	The workspace in which to create the new ghost operation.

Creates a ghost operation; a Placeholder clone of the specified operation with exactly the same inputs / outputs.

createGhostOutputs()

int createGhostOutputs ( const DataExecution::ObjectArray &  outputDifferences, DataExecution::Operation &  operation, ComparisonRole  desc  ) const

protected

Parameters

outputDifferences	Array of differences between outputs in two different workflows.
operation	The operation onto which to add outputs that do not exist.
desc	The workflow descriptor indicating whether workspace is taking the role of workflow A or workflow B in the comparison

Returns

The number of outputs created.

findOperation()

bool findOperation ( QUuid  guid, DataExecution::Operation **  operation, DataExecution::Workspace **  workspace  )

static

Looks for an operation given a target uuid and a parent workspace. The workspace is searched recursively

If the operation is found, then the workspace is updated to hold the direct parent workspace of the operation

Parameters

guid	The Uuid of the target operation
operation	Operation address returned (if found)
workspace	Parent workspace. Set this to a top-level workspace that should

Returns

true if the operation is found

findWorkspace()

bool findWorkspace ( QUuid  guid, DataExecution::Workspace **  workspace  )

static

processDifferences()

void processDifferences	(	const DataExecution::ObjectArray &	differences,
		DataExecution::Workspace &	workspace,
		ComparisonRole	desc,
		DataExecution::Workspace &	otherWorkspace
	)

Now that we've created any and all ghost operations, we can look for missing connections. There are two ways missing connections will be identified:

1. Where there are connection differences recorded
2. Where ghost operations are created. No connection differences will be recorded in this case, because the specific operation the connection differences are stored against is not present in this workflow.
