Constructor Detail

ExpressionNode

public ExpressionNode(ExpressionNodeManager manager,
                      ExpressionNode parent)

Method Detail

getParentNode

public ExpressionNode getParentNode()

getChildNodes

public java.util.List<ExpressionNode> getChildNodes()

getNodeType

public abstract int getNodeType()

Return a value defined by NODETYPE_* constants.

getExpression

public abstract java.lang.String getExpression()

The full expression that this node represents. E.g. "#{aa.bb.cc}" or ".{aa.bb.cc}".

getText

public abstract java.lang.String getText()

The text that is shown for this node.

loadChildNodes

public abstract void loadChildNodes()

This method is called prior to calling getChildNodes() by the Expression Explorer. you need to create the childe node instances and add them to m_childNodes. This method is called when the user toggles a node - at this point of time the next level of nodes is read.

getImage

public java.lang.String getImage()

You may specify a special image for this node - otherwise default images are used. Pay attention: the image must refer to the editor's web application - this is the one where images are loaded from by the tool environment. A valid image name e.g. is "/editor/images/icons/lightning.png". Check the corresponding directory of the editor web application in order to see what images are available.
