Examples with ComponentGenerationException com.vaadin.generator.exception.ComponentGenerationException used on opensource projects

Example 1 with ComponentGenerationException

use of com.vaadin.generator.exception.ComponentGenerationException in project flow by vaadin.

the class ComponentGenerator method generateClass.

/**
 * Generates the Java class by using the {@link ComponentMetadata} object.
 *
 * @param metadata
 *            The webcomponent metadata.
 * @param targetPath
 *            The output base directory for the generated Java file.
 * @param basePackage
 *            The base package to be used for the generated Java class. The
 *            final package of the class is basePackage plus the
 *            {@link ComponentMetadata#getBaseUrl()}.
 * @param licenseNote
 *            A note to be added on top of the class as a comment. Usually
 *            used for license headers.
 * @throws ComponentGenerationException
 *             If an error occurs when generating the class.
