JrtClassPath

dotty.tools.dotc.classpath.JrtClassPath
See theJrtClassPath companion object
final class JrtClassPath(fs: FileSystem) extends ClassPath

Implementation ClassPath based on the JDK 9 encapsulated runtime modules (JEP-220)

https://bugs.openjdk.java.net/browse/JDK-8066492 is the most up to date reference for the structure of the jrt:// filesystem.

The implementation assumes that no classes exist in the empty package.

Concrete methods

def asURLs: Seq[URL]
def findClassFile(className: String): Option[AbstractFile]

Returns the classfile for an external name, e.g., "java.lang.String". This method does not return source files.

Returns the classfile for an external name, e.g., "java.lang.String". This method does not return source files.

This method is used by the classfile parser. When parsing a Java class, its own inner classes are entered with a ClassfileLoader that parses the classfile returned by this method. It is also used in the backend, by the inliner, to obtain the bytecode when inlining from the classpath. It's also used by scalap.

def findClass(className: String): Option[ClassRepresentation]

Returns the class file and / or source file for a given external name, e.g., "java.lang.String". If there is both a class file and source file, the compiler can decide whether to read the class file or compile the source file.

Returns the class file and / or source file for a given external name, e.g., "java.lang.String". If there is both a class file and source file, the compiler can decide whether to read the class file or compile the source file.

Internally this seems to be used only by ScriptRunner, but only to call .isDefined. That could probably be implemented differently.

Externally, it is used by sbt's compiler interface: https://github.com/sbt/sbt/blob/v0.13.15/compile/interface/src/main/scala/xsbt/CompilerInterface.scala#L249 Jason has some improvements for that in the works (https://github.com/scala/bug/issues/10289#issuecomment-310022699)
