Class IntraDOCPDataFlavor

java.lang.Object
  java.awt.datatransfer.DataFlavor
      com.levigo.jadice.document.flavor.IntraDOCPDataFlavor

All Implemented Interfaces:

Externalizable, Serializable, Cloneable

public class IntraDOCPDataFlavor
extends DataFlavor

A DataFlavor used for moving or copying Pages across jadice application running in different JVMs.

This flavor keeps track from which JVM it was created so that the receiving side can decide if it will support this flavor or not. Due to some JVM internal issues this must information is coded into the MIME type so that this flavor has no fixed MIME type.

Field Detail

INTRA_DOCP_MIME_TYPE_PREFIX

public static final String INTRA_DOCP_MIME_TYPE_PREFIX

The prefix of the MIME type. Additional information about the JVM instance and the version of the transfer protocol are added at runtime

Constant Field Values

VERSION

public static final String VERSION

The current version of the protocol for intra DOCP transfer. This value might change in the future so that the internal transfer mechanism can ensure backward compatibility if it exchanges data with a prior version.

Method Detail

get

public static IntraDOCPDataFlavor get()

Returns:

the IntraDOCPDataFlavor for the current JVM instance.

isIntraDOCPDataFlavor

public static boolean isIntraDOCPDataFlavor(DataFlavor flavor)

Checks if the given flavor is an IntraDOCPDataFlavor.

Parameters:

flavor - the DataFlavor to check.

Returns:

true iff the given flavor is an IntraDOCPDataFlavor.

isFromSameJVM

public static boolean isFromSameJVM(DataFlavor flavor)

Checks if the given flavor is an IntraDOCPDataFlavor from the same JVM.

Parameters:

flavor - the DataFlavor to check

Returns:

true iff the given flaovr is an IntraDOCPDataFlavor from the same JVM.

getVersion

public static String getVersion(DataFlavor flavor)

Returns the version number of the given flavor. This is used to ensure backward compatibility with prior versions if the internal transfer protocol might change in the future

Parameters:

flavor - the DataFlavor from which to retrieve the version

Returns:

the version number or null if given flavor is no IntraDOCPDataFlavor.
