AggregateClassPath

case class AggregateClassPath(aggregates: Seq[ClassPath]) extends ClassPath

A classpath unifying multiple class- and sourcepath entries. The Classpath can obtain entries for classes and sources independently so it tries to do operations quite optimally - iterating only these collections which are needed in the given moment and only as far as it's necessary.

Value parameters:
aggregates

classpath instances containing entries which this class processes

Companion:
object
trait Product
trait Equals
trait ClassPath
class Object
trait Matchable
class Any

override def asSourcePathString: String

The whole sourcepath in the form of one String.

override 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.

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)

override 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.
