Type Members

1. class Counter extends AnyRef

   

   Thread-safe counters.

   Thread-safe counters. This class provides an operation that can be used to generate a sequence of integer values. Instances of this class are useful for generating things like unique names for generated entities. The methods synchronize on the counter value so they can be called safely from more than one thread.

   init is the initial value of the counter (default: -1).

2. abstract class Emitter extends AnyRef

   

   Class of objects that can emit text.

3. abstract class Entity extends AnyRef

   

   An entity that represents some program object.

4. trait Environments[E <: Entity] extends AnyRef

   

   General implementation of environments as stacked scopes.

   General implementation of environments as stacked scopes. The objects associated with names in environments are of type E which must be a subtype of the general Entity class.

5. class FileEmitter extends StringEmitter

   

   A string emitter that also provides a close method to send the result to the named UTF-8 encoded file.

6. case class FileSource(name: String, encoding: String = "UTF-8") extends Source with Product with Serializable

   

   A source that is a named file.

7. class Memoiser[T, U] extends AnyRef

   

   A memoiser that can store arbitrary values of type U under keys of type T.

   A memoiser that can store arbitrary values of type U under keys of type T. The behaviour of the memoiser can be adjusted by selecting an appropriate type.

8. sealed abstract class MemoiserType extends AnyRef

   

   The types of memoiser that can be created.

9. case class Message(value: AnyRef, label: String) extends Product with Serializable

   

   A message record consisting of a value with which the message is associated, a label string, and a severity (which defaults to error).

10. class Messaging extends AnyRef

    

    General facility for processing messages relative to positioned values.

11. class OutputEmitter extends Emitter

    

    Class of objects that can emit arbitrary output.

    Class of objects that can emit arbitrary output. The output is sent to standard output. Use an ErrorEmitter if your output is signalling errors, warnings, log messages or similar.

12. case class Position(line: Int, column: Int, source: Source) extends Product with Serializable

    

    Record of a source position at a particular line and column relative to a given source.

    Record of a source position at a particular line and column relative to a given source. The line and column numbers are one-indexed.

13. class Positions extends AnyRef

    

    Record of source positions that correspond to program elements.

14. trait Source extends AnyRef

    

    A simple source of characters.

15. class StringEmitter extends Emitter

    

    An emitter that records the output in a string that can be accessed via the result method.

16. case class StringSource(content: String, name: String = "") extends Source with Product with Serializable

    

    A source that is a string.

17. class WeakIdentityHashSet[T] extends AnyRef

    

    A simple set that compares elements by identity.
