Modifier and Type	Method and Description
java.util.List	getApplicableDataAndPositions(CmtModel model, java.util.List positions, oracle.javatools.datatransfer.ExtendedTransferable transferable) Gets the possible TransferDataInfos upon which this action could be applied near the given position, and also returns the actual position at which the operation could be performed.

getApplicableDataAndPositions

public final java.util.List getApplicableDataAndPositions(CmtModel model,
                                                          java.util.List positions,
                                                          oracle.javatools.datatransfer.ExtendedTransferable transferable)

Description copied from class: Operation

Gets the possible TransferDataInfos upon which this action could be applied near the given position, and also returns the actual position at which the operation could be performed.

Specified by:

getApplicableDataAndPositions in class Operation

Parameters:

model - Model on which the operation may be applied

positions - List of CmtModelNodes to consider. The order of this list should be preserved in any return DataAndPosition.

transferable - Data being transfered

Returns:

List of DataAndPositions to be applied "near" the given position list, ordered by suitability (first return is most preferable datum). Each DataAndPosition's position list should be in a similar order to the positions parameter.

getApplicableDataAndPositionsImpl

protected abstract java.util.List getApplicableDataAndPositionsImpl(CmtModel model,
                                                                    java.util.List positions,
                                                                    java.util.List dataInfos)

Returns the list of DataAndPositions instances, like getApplicableDataAndPositions(oracle.jdeveloper.cmt.CmtModel, java.util.List, oracle.javatools.datatransfer.ExtendedTransferable).

Parameters:

model - Abstract model

positions - List of positions to consider

dataInfos - List of data infos to consider, all of which will be of the getRequiredDataFlavor() flavor.

getRequiredDataFlavor

protected abstract java.awt.datatransfer.DataFlavor getRequiredDataFlavor()

Gets the data flavor this operation requires. If this operation consumes more than one flavor, this abstract class is not suitable.
