Readable

public interface Readable

java.lang.Readable

Known indirect subclasses

BufferedReader, CharArrayReader, CharBuffer, FileReader, FilterReader, InputStreamReader, LineNumberReader, PipedReader, PushbackReader, Reader, StringReader

BufferedReader	Reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.
CharArrayReader	This class implements a character buffer that can be used as a character-input stream.
CharBuffer	A char buffer.
FileReader	Convenience class for reading character files.
FilterReader	Abstract class for reading filtered character streams.
InputStreamReader	An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and decodes them into characters using a specified `charset`.
LineNumberReader	A buffered character-input stream that keeps track of line numbers.
PipedReader	Piped character-input streams.
PushbackReader	A character-stream reader that allows characters to be pushed back into the stream.
Reader	Abstract class for reading character streams.
StringReader	A character stream whose source is a string.

A Readable is a source of characters. Characters from a Readable are made available to callers of the read method via a CharBuffer.

Summary

Public methods
`abstract int`	`read(CharBuffer cb)` Attempts to read characters into the specified character buffer.

Public methods

read

public abstract int read (CharBuffer cb)

Attempts to read characters into the specified character buffer. The buffer is used as a repository of characters as-is: the only changes made are the results of a put operation. No flipping or rewinding of the buffer is performed.

Parameters
`cb`	`CharBuffer`: the buffer to read characters into

Returns
`int`	The number of `char` values added to the buffer, or -1 if this source of characters is at its end

Throws
`IOException`	if an I/O error occurs
`NullPointerException`	if cb is null
`ReadOnlyBufferException`	if cb is a read only buffer
