Constructor Detail

DefaultNode

public DefaultNode()

Constructor that initializes a node which contains the empty string as its node text.

DefaultNode

public DefaultNode(String pText)

Constructor.

Parameters:

pText - the node's text

DefaultNode

public DefaultNode(@Nullable
                   String pText,
                   @Nullable
                   String pKey,
                   @Nullable
                   NodeColor pColorOverride,
                   @Nullable
                   String pAnnotation,
                   @Nullable
                   List<Node> pChildren)

Method Detail

addChild

public void addChild(@Nullable
                     Node pChild)

getAnnotation

@CheckForNull
public String getAnnotation()

Description copied from interface: Node

Return a String here to display as a node annotation. May contain line breaks.

Specified by:

getAnnotation in interface Node

Returns:

the annotation, or null for no annotation

getChildren

@Nonnull
public Iterable<Node> getChildren()

Description copied from interface: Node

The node's child nodes. This method may be called multiple times, and it is expected to return the same elements on each invocation. Nodes returned by this iterator may also be null (shouldn't, but we can handle it).

Specified by:

getChildren in interface Node

Returns:

the list of child nodes, or null / empty if this is a leaf node

getColor

@CheckForNull
public NodeColor getColor()

Description copied from interface: Node

Return a color here for colored nodes. The color set here takes precedence over the tree's color scheme.

Specified by:

getColor in interface Node

Returns:

the node color, or null to use the color from the tree's color scheme. A value of NodeColor.None indicates that the node must not be colored.

getKey

@CheckForNull
public String getKey()

Description copied from interface: Node

An optional primary key for the node. This can be used to identify nodes for cycle detection. It defaults to the node text if not overridden. The value returned from this method is used only if the IdentityScheme.ByKey is explicitly selected. Otherwise, this method should be left to its default implementation.

If you actually use this value (because you've chosen IdentityScheme.ByKey), then you should make sure that it not return null. All nodes which do that will be considered the same node then (which may be what you want. I'm just saying).

Specified by:

getKey in interface Node

Returns:

an identifying String

getText

@CheckForNull
public String getText()

Description copied from interface: Node

The node's text. May contain line breaks.

Specified by:

getText in interface Node

Returns:

the node's text

setAnnotation

public void setAnnotation(@Nullable
                          String pAnnotation)

setChildren

public void setChildren(@Nullable
                        List<Node> pChildren)

setColor

public void setColor(@Nullable
                     NodeColor pColorOverride)

setKey

public void setKey(@Nullable
                   String pKey)

setText

public void setText(@Nullable
                    String pText)
