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 Reads text from character files using a default buffer size. 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.

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
