Method Details

visitAssembly

public RESULT visitAssembly(IAssemblyNodeItem item,
 CONTEXT context)

Description copied from interface: INodeItemVisitor

This callback is called when an IAssemblyNodeItem is visited.

Specified by:

visitAssembly in interface INodeItemVisitor<CONTEXT,RESULT>

Overrides:

visitAssembly in class AbstractNodeItemVisitor<CONTEXT,RESULT>

Parameters:

item - the visited item

context - provides contextual information for use by the visitor

Returns:

the visitation result

isDecendant

protected boolean isDecendant(IAssemblyNodeItem node,
 IAssemblyDefinition assemblyDefinition)

Determines if the provided node is a descendant of the assembly definition.

Parameters:

node - the node item to test

assemblyDefinition - the assembly definition to determine as an ancestor of the node

Returns:

true if the assembly definition is the node's ancestor, or false otherwise
