29 * Implementations of this interface can supply type-safe classes for statements. Implementation
30 * classes are typically invoked when the YANG statement tree is being built from the YANG DOM tree.
31 * For YANG core statements as defined in RFC 7950, {@link YangCoreClassSupplier} will be used. Other
32 * implementations typically handle extensions.

36 public interface StatementClassSupplier {
39 * Returns information about the statements that this implementation can handle.
41 * The map keys are the names of modules. The map value is a list of statement names
42 * that are defined within that module, and which the implementation can handle.
44 Map<String, List<String>> getHandledStatements();
47 * Returns the Java class that represents the YANG statement.
49 * Implementations will return either a specific class that can handle the statement or null.
51 * If the statement represents an extension, either {@link ExtensionStatement} or a subclass of
52 * {@link ExtensionStatement} must be returned. Failure to do so will lead to parse errors.
54 * The supplied method <b>must</b> have a constructor as follows, and invoke super:
57 * public class MyStatement extends ExtensionStatement {
59 * public MyStatement(final AbstractStatement parentStatement, final YangDomElement domElement) {
60 * super(parentStatement, domElement);
66 <T extends AbstractStatement> Class<T> getJavaClazzForStatement(String moduleName, String statementName);
