Readable

interface Readable

java.lang.Readable

Known Direct Subclasses

CharBuffer, Reader

CharBuffer	A char buffer.
Reader	Abstract class for reading character streams.

Known Indirect Subclasses

BufferedReader, CharArrayReader, FileReader, FilterReader, InputStreamReader, LineNumberReader, PipedReader, PushbackReader, 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.
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 .
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.
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(cb: CharBuffer!)` Attempts to read characters into the specified character buffer.

Public methods

read

Added in API level 1

abstract fun read(cb: CharBuffer!): Int

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

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

Exceptions
`java.io.IOException`	if an I/O error occurs
`java.lang.NullPointerException`	if cb is null
`java.nio.ReadOnlyBufferException`	if cb is a read only buffer
