| * Send your graphs to <b>IGV</b> via a socket or a file. This package allows one to easily encode |
| * any graph-like data structure and send it for visualization to <em>OracleLab's Ideal Graph |
| * Visualizer</em> tool. Assuming you already have your own data structure that contains |
| * <b>nodes</b> and <b>edges</b> among them, creating a {@link org.graalvm.graphio.GraphOutput} |
| * specialized for your data is a matter of implementing a single interface: |
| * |
| * {@link org.graalvm.graphio.GraphJavadocSnippets#acmeGraphStructure} |
| * |
| * The {@link org.graalvm.graphio.GraphStructure} interface defines the set of operations that are |
| * needed by the <em>graph protocol</em> to encode a graph into the <b>IGV</b> expected format. The |
| * graph structure is implemented as a so called |
| * <a href="http://wiki.apidesign.org/wiki/Singletonizer">singletonizer</a> API pattern: there is no |
| * need to change your data structures or implement some special interfaces - everything needed is |
| * provided by implementing the {@link org.graalvm.graphio.GraphStructure} operations. |
| * <p> |
| * The next step is to turn this graph structure into an instance of |
| * {@link org.graalvm.graphio.GraphOutput}. To do so use the associated |
| * {@link org.graalvm.graphio.GraphOutput.Builder builder} just like shown in the following method: |
| * |
| * {@link org.graalvm.graphio.GraphJavadocSnippets#buildOutput} |
| * |
| * Now you are ready to dump your graph into <b>IGV</b>. Where to obtain the right channel? One |
| * option is to create a {@link java.nio.channels.FileChannel} and dump the data into a file |
| * (preferrably with <code>.bgv</code> extension). The other is to open a socket to port |
| * <code>4445</code> (the default port <b>IGV</b> listens to) and dump the data there. Here is an |
| * example: |
| * |
| * {@link org.graalvm.graphio.GraphJavadocSnippets#dump} |
| * |
| * Call the {@code dump} method with pointer to file {@code diamond.bgv} and then you can open the |
| * file in <b>IGV</b>. The result will look like this: |
| * <p> |
| * <img src="doc-files/diamond.png"> |
| * <p> |
| * You can verify the behavior directly in the <b>IGV</b> by downloading |
| * <a href="doc-files/diamond.bgv">diamond.bgv</a> file generated from the above diamond structure |
| * graph. |
| * <p> |
| * The primary <b>IGV</b> focus is on graphs used by Graal compiler. As such they aren't plain |
| * graphs, but contain various compiler oriented attributes: |
| * <ul> |
| * <li>{@linkplain org.graalvm.graphio.GraphBlocks code blocks} information</li> |
| * <li>{@linkplain org.graalvm.graphio.GraphElements method and fields} information</li> |
| * <li>Advanced support for {@linkplain org.graalvm.graphio.GraphTypes recognizing types}</li> |
| * </ul> |
| * all these additional interfaces ({@link org.graalvm.graphio.GraphBlocks}, |
| * {@link org.graalvm.graphio.GraphElements} and {@link org.graalvm.graphio.GraphTypes}) are |
| * optional - they don't have to be provided. As such they can be specified via |
| * {@link org.graalvm.graphio.GraphOutput.Builder} instance methods, which may, but need not be |
| * called at all. Here is an example: |
| * |
| * {@link org.graalvm.graphio.GraphJavadocSnippets#buildAll} |
| * |
| * All these interfaces follow the |
| * <a href="http://wiki.apidesign.org/wiki/Singletonizer">singletonizer</a> API pattern again - e.g. |
| * no need to change your existing data structures, just implement the operations provided by the |
| * interfaces you pass into the builder. By combining these interfaces together you can get as rich, |
| * colorful, source linked graphs as Graal compiler produces to describe its optimizations. |
