{DefaultSeekableBufferedInputStream-of t:Type} (class)
public DefaultSeekableBufferedInputStream-of {inherits {DefaultBufferedInputStream-of t}, {InputStreamBufferSeekable-of t}, {SeekableBufferedInputStream-of t}}
Package: CURL.IO.STREAM
Direct Known Subclasses: DefaultSeekableTextInputStream

This is a generic full implementation of a SeekableBufferedInputStream-of that takes an unbuffered SeekableInputStream-of and buffers calls to it.

Constructor Details
default (constructor)
public {DefaultSeekableBufferedInputStream-of.default
    stream:{SeekableInputStream-of t},
    close-stream-on-close?:bool = true,
    buffer-size:int = {calculate-instances-per-memory-size default-buffer-memory-size, t },
    unread-size:int = {max {min 4, buffer-size div 4}, 1}
}
stream: SeekableInputStream-of to be wrapped by buffering.
close-stream-on-close?: specifies whether this class's close method should invoke close on the underlying stream.
buffer-size: Approximately how many items the main buffer should hold. Must be greater than 0.
unread-size: Approximately how many items should be able to be held for successive unread-one operations.

Notes

The amount of space available for unreading can grow dynamically, but such growth is expensive. Unread space is never used for other purposes. The main buffer will not grow.

Property Details
input-seekable (accessor)
accessor protected DefaultSeekableBufferedInputStream-of.input-seekable:Seekable

Returns the underlying Seekable.

Overriding

Must be provided by a subclass.

seek-input-stream-buffer (accessor)
accessor protected DefaultSeekableBufferedInputStream-of.seek-input-stream-buffer:{InputStreamBuffer-of t}

Returns the underlying InputStreamBuffer-of.

Overriding

Must be provided by a subclass.
