Examples with NamedTransformer org.cytoscape.filter.model.NamedTransformer used on opensource projects

Example 6 with NamedTransformer

use of org.cytoscape.filter.model.NamedTransformer in project cytoscape-impl by cytoscape.

the class FilterIOTest method testLoadOldTopologyFilter.

/**
 * The topology filter was made a composite filter in 3.3. Older versions of cytoscape
 * will export a topology filter without the "transformers" field that is part of
 * composite filters. The filter json parser was enhanced to support this.
