Class JavaDiagnosticReader

java.lang.Object

org.checkerframework.framework.test.diagnostics.JavaDiagnosticReader

All Implemented Interfaces:

Iterator<TestDiagnosticLine>

public class JavaDiagnosticReader
extends Object
implements Iterator<TestDiagnosticLine>

Reads a file that has serialized javac diagnostics and returns either a list of TestDiagnosticLines or TestDiagnostics. This file might either:

• a Java file, which is read by creating a JavaDiagnosticReader with the JAVA_COMMENT_CODEC
• a "Diagnostic" file, which is read by creating a JavaDiagnosticReader with a DIAGNOSTIC_FILE_CODEC
