Interface GraphFormatter<V,E>

All Known Implementing Classes:

GraphFormatterBare, PropertyBasedFormatter

public interface GraphFormatter<V,E>

A GraphFormatter is an auxiliary object that assists when exporting a graph to another format. One (and the primary) use of this interface is in the generation of "fancy" DOT files. For example, nodes can have different colors depending on some attribute or contition. In such a case, it possible to write a formatter that adds the required extra attributes using the DOT language. Thus, this interface tries to isolate the exporter (see DotExporter) from the details of deciding which DOT attributes to emit.

Note that the return value of each method below is context-dependent, so the comments are only general.
