public interface BuilderNode

In a groovy node builder environment, there is often one class per node that is possible in a builder. This interface provides the necessary validation and interaction methods for the mediator (The GroovyNodeBuilder object) to figure out who should handle what.

Method Summary

Object	createNewNode(Object current, Map attributes) Execute the handler for the given node builder.
String	getNodeName() Retrieve the name of the node.
Set	getSupportedAttributes() Retrieve a map of supported attribute names.
void	validateScriptedAttributes(Map specifiedAttributes) Validates a given map of attributes as supplied by the GroovyNodeBuilder against the node's supported attributes.

Method Detail

getNodeName

String getNodeName()

Retrieve the name of the node. Examples could be 'container' or 'component'.

Returns:

String

getSupportedAttributes

Set getSupportedAttributes()

Retrieve a map of supported attribute names.

void validateScriptedAttributes(Map specifiedAttributes)
                                throws org.nanocontainer.script.NanoContainerMarkupException

Parameters:

specifiedAttributes - Map

Throws:

org.nanocontainer.script.NanoContainerMarkupException

createNewNode

Object createNewNode(Object current,
                     Map attributes)
                     throws org.nanocontainer.script.NanoContainerMarkupException

Execute the handler for the given node builder.

Parameters:

current - the current object. May be null for no parent container.
