Type Members

1.  trait ByteData extends AnyRef

   Encapsulates an Array[Byte] and provides convenience methods for reading the data out of it.

2.  class Bytes extends AnyRef

   Trivial wrapper around Array[Byte] with sane equality and useful toString

3.  trait Generator[+A] extends AnyRef

   Provides the geny.Gen data type, A Generator of elements of type A.

   Provides the geny.Gen data type, A Generator of elements of type A.

   Generator is basically the inverse of a scala.Iterator: instead of the core functionality being the pull-based hasNext and next: T methods, the core is based around the push-based generate method. generate is basically an extra-customizable version of foreach, which allows the person calling it to provide basic control-flow instructions to the upstream Gens.

   Unlike a scala.Iterator, subclasses of Generator can guarantee any clean up logic is performed by placing it after the generate call is made.

   Transformations on a Generator are lazy: calling methods like filter or map do not evaluate the entire Gen, but instead construct a new Gen that delegates to the original. The only methods that evaluate the Generator are the "Action" methods like generate/foreach/find, or the "Conversion" methods like toArray or similar.

   generate takes a function returning Gen.Action rather that Unit. This allows a downstream Gen to provide basic control commands to the upstream Gens: i.e. Generator.End to cease enumeration of the upstream Gen. This allows it to avoid traversing and processing elements that the downstream Gen doesn't want/need to see anyway.

4.  trait Readable extends Writable

   A Readable is a source of bytes that can be read from an InputStream

   A Readable is a source of bytes that can be read from an InputStream

   A subtype of Writable, every Readable can be trivially used as a Writable by transferring the bytes from the InputStream to the OutputStream, but not every Writable is a Readable.

   Note that the InputStream is only available inside the readBytesThrough, and may be closed and cleaned up (along with any associated resources) once the callback returns.

5.  trait Writable extends AnyRef

   A Writable is a source of bytes that can be written to an OutputStream.

   A Writable is a source of bytes that can be written to an OutputStream.

   Essentially a push-based version of java.io.InputStream, that allows an implementation to guarantee that cleanup logic runs after the bytes are written.

   Writable is also much easier to implement than java.io.InputStream: any code that previously wrote output to an ByteArrayOutputStream or StringBuilder can trivially satisfy the Writable interface. That makes Writable very convenient to use for allowing zero-friction zero-overhead streaming data exchange between different libraries.

   Writable comes with implicit constructors from Array[Byte], String and InputStream, and is itself a tiny interface with minimal functionality. Libraries using Writable are expected to extend it to provide additional methods or additional implicit constructors that make sense in their context.
