Class LinkRegistryAdapter

java.lang.Object
  freemind.modes.LinkRegistryAdapter

All Implemented Interfaces:

MindMapLinkRegistry

public class LinkRegistryAdapter

extends java.lang.Object

implements MindMapLinkRegistry

Interface for the registry, which manages the ids of nodes and the existing links in a map. Thus, this interface is bound to a map model, because other maps have a different registry.

Nested Class Summary

class	LinkRegistryAdapter.ID_BasicStateAdapter State parent interface.
class	LinkRegistryAdapter.ID_BlankAdapter This state interface expresses the state that a node is blank (i.e.
protected class	LinkRegistryAdapter.ID_RegisteredAdapter This state interface expresses the state that a node has an ID.
protected class	LinkRegistryAdapter.ID_UsedStateAdapter This state interface expresses the state that a node has an ID, but is abstract.

Method Detail

generateUniqueID

public java.lang.String generateUniqueID(java.lang.String proposedID)

Description copied from interface: MindMapLinkRegistry

This can be used, if the id has to be known, before a node can be labled.

Specified by:

generateUniqueID in interface MindMapLinkRegistry

generateUniqueLinkID

public java.lang.String generateUniqueLinkID(java.lang.String proposedID)

Description copied from interface: MindMapLinkRegistry

This can be used, if the id has to be known, before a link can be labled.

Specified by:

generateUniqueLinkID in interface MindMapLinkRegistry

registerLinkTarget

public MindMapLinkRegistry.ID_Registered registerLinkTarget(MindMapNode target)

The main method. Registeres a node with a new (or an existing) node-id. If the state of the id is pending, then it is set to registered again.

Specified by:

registerLinkTarget in interface MindMapLinkRegistry

registerLinkTarget

public MindMapLinkRegistry.ID_Registered registerLinkTarget(MindMapNode target,
                                                            java.lang.String proposedID)

Description copied from interface: MindMapLinkRegistry

The second variant of the main method. The difference is that here an ID is proposed, but has not to be taken, though.

Specified by:

registerLinkTarget in interface MindMapLinkRegistry

getState

public MindMapLinkRegistry.ID_BasicState getState(MindMapNode node)

Specified by:

getState in interface MindMapLinkRegistry

getTargetForID

public MindMapNode getTargetForID(java.lang.String ID)

Description copied from interface: MindMapLinkRegistry

Reverses the getLabel method: searches for a node with the id given as the argument.

Specified by:

getTargetForID in interface MindMapLinkRegistry

deregisterLinkTarget

public void deregisterLinkTarget(MindMapNode target)
                          throws java.lang.IllegalArgumentException

Exception if there are still targets registered.

Specified by:

deregisterLinkTarget in interface MindMapLinkRegistry

Throws:

java.lang.IllegalArgumentException

registerLink

public void registerLink(MindMapLink link)
                  throws java.lang.IllegalArgumentException

Method to keep track of the sources associated to a target node. This method also sets the new id to the target. Moreover, it is not required that the target node is already registered. This will be done on the fly.

Specified by:

registerLink in interface MindMapLinkRegistry

Throws:

java.lang.IllegalArgumentException

deregisterLink

public void deregisterLink(MindMapLink link)

Specified by:

deregisterLink in interface MindMapLinkRegistry

getLinkForID

public MindMapLink getLinkForID(java.lang.String ID)

Description copied from interface: MindMapLinkRegistry

Reverses the getUniqueID method: searches for a link with the id given as the argument.

Specified by:

getLinkForID in interface MindMapLinkRegistry

getAllSources

public java.util.Vector getAllSources(MindMapNode target)

Returns a Vector of Nodes that point to the given target node.

Specified by:

getAllSources in interface MindMapLinkRegistry

getAllLinks

public java.util.Vector getAllLinks(MindMapNode node)

Specified by:

getAllLinks in interface MindMapLinkRegistry

Returns:

returns all links from or to this node.

getAllLinksIntoMe

public java.util.Vector getAllLinksIntoMe(MindMapNode target)

Specified by:

getAllLinksIntoMe in interface MindMapLinkRegistry

Returns:

returns all links to this node.

getAllLinksFromMe

public java.util.Vector getAllLinksFromMe(MindMapNode source)

Specified by:

getAllLinksFromMe in interface MindMapLinkRegistry

Returns:

returns all links from this node.

getLabel

public java.lang.String getLabel(MindMapNode target)

Specified by:

getLabel in interface MindMapLinkRegistry

cutNode

public void cutNode(MindMapNode target)

Description copied from interface: MindMapLinkRegistry

Removes links to all nodes beginning from target with its children.

Specified by:

cutNode in interface MindMapLinkRegistry

clearCuttedNodeBuffer

public void clearCuttedNodeBuffer()

Clears the set of recent cutted nodes.

Specified by:

clearCuttedNodeBuffer in interface MindMapLinkRegistry

getCuttedNode

public java.util.Vector getCuttedNode(java.lang.String oldTargetID)

Specified by:

getCuttedNode in interface MindMapLinkRegistry

Returns:
