Constructor Detail

AbstractRDFObjectTreeNodeRepresentationStrategy

public AbstractRDFObjectTreeNodeRepresentationStrategy(com.globalmentor.rdf.RDFXMLGenerator rdfXMLifier)

RDF XMLifier constructor.

Parameters:

rdfXMLifier - The RDF XMLifier to use for creating labels.

Throws:

java.lang.NullPointerException - if the given RDF XMLifier is null.

Method Detail

getXMLGenerator

public com.globalmentor.rdf.RDFXMLGenerator getXMLGenerator()

Returns:

The RDF XMLifier to use for creating labels.

createComponent

public <N extends V> Label createComponent(TreeControl treeControl,
                                           TreeModel model,
                                           TreeNodeModel<N> treeNode,
                                           boolean editable,
                                           boolean selected,
                                           boolean focused)

Creates a component to represent the given tree node. This implementation returns a label with an appropriate string value to represent the RDF object.

Type Parameters:

N - The type of value contained in the node.

Parameters:

treeControl - The component containing the model.

model - The model containing the value.

treeNode - The node containing the value.

editable - Whether values in this column are editable.

selected - true if the value is selected.

focused - true if the value has the focus.

Returns:

A new component to represent the given value.

createInfoModel

protected <N extends V> InfoModel createInfoModel(TreeControl treeControl,
                                                  TreeModel model,
                                                  TreeNodeModel<N> treeNode)

Creates an info model for the representation label.

Type Parameters:

N - The type of value contained in the node.

Parameters:

treeControl - The component containing the model.

model - The model containing the value.

treeNode - The node containing the value.

Returns:

The label model to use for the label.

buildLabelText

protected java.lang.StringBuilder buildLabelText(java.lang.StringBuilder stringBuilder,
                                                 TreeControl treeControl,
                                                 TreeModel model,
                                                 TreeNodeModel<? extends V> treeNode,
                                                 V value)

Builds the label to be used for a tree node. If the tree node is an RDFObjectTreeNodeModel, this version prepends a representation of its property.

Type Parameters:

N - The type of value contained in the node.

Parameters:

stringBuilder - The string builder to hold the label text.

treeControl - The component containing the model.

model - The model containing the value.

treeNode - The node containing the value.

value - The value contained in the node.

Returns:

The string builder used to construct the label.
