Known Indirect Subclasses | 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.

Public methods
read
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 |
