use of org.eclipse.n4js.runner.exceptions.DependencyCycleDetectedException in project n4js by eclipse.

the class SupportingRunnerPropertyTester method test.

/**
 * Check if given receiver object is supported by given runner. Runner is specified by first arguments in args
 * parameter which is expected to be runner key value.
 *
 * @param receiver
 *            is either {@link FileEditorInput} or {@link IFile} to be check against runner.
 * @param property
 *            used to verify callers are invoking correct tester.
 * @param args
 *            expected to contain {@link String} representing runner key of the runner to test.
 * @param expectedValue
 *            not really used
