Constructor Detail

QueryTreeModel

public QueryTreeModel(QueryInformationModel q,
                      AttributeList filter,
                      int debugLevel)
               throws DicomException

Construct a tree model with a root node on top.

The root node is the name of the called AET in the query information model.

The contents are added as required by actually performing queries as nodes are expanded.

Parameters:

q - the query information model to build the tree from

filter - the query request identifier as a list of DICOM attributes

debugLevel - 0 is no debugging (silent), > 0 more verbose levels of debugging

Throws:

DicomException - thrown if there are problems building the tree
