Public Class CoderReader Implements Reader

A Reader whose bytes are what another Reader's come to through a Coder, as CoderReader(file, GzipDecompressor()) reads a .gz file's: it reads the other Reader a chunk at a time, and once that ends, gives what the Coder has left, and then ends. Read throws the IOError the Coder or the Reader does, like a Decompressor's for bytes that aren't its format, or that end early, and a Read after that throws again, or ends.

Examples

Local gz = Gzip.Compress("read back".Bytes)
Local reader = CoderReader(MemoryStream(gz), GzipDecompressor())
Expect(Try ReadAllText(reader) == "read back")

Public New(inner: Reader, through: Coder) constructor #

A CoderReader that reads what through makes of what inner gives.
Public Method Read(into: Buffer<UInt8>): Int64 Throws IOError method #

Reads what the other Reader's bytes come to through the Coder into into, and gives how many it read, or 0 once both have ended. Throws the IOError the Coder or the other Reader does.
