## java.io
Class StringBufferInputStream

    java.lang.Object
      java.io.InputStream
          java.io.StringBufferInputStream

All Implemented Interfaces:
  Closeable

Deprecated. This class does not properly convert characters into bytes. As of JDK 1.1, the preferred way to create a stream from a string is via the `StringReader` class.

    @Deprecated
    public class StringBufferInputStream

extends InputStream

This class allows an application to create an input stream in which the bytes read are supplied by the contents of a string. Applications can also read bytes from a byte array by using a `ByteArrayInputStream`.

Only the low eight bits of each character in the string are used by this class.

Since:
  JDK1.0
See Also:
  `ByteArrayInputStream`, `StringReader`

Field Summary
`protected String` | `buffer` Deprecated. The string from which bytes are read.
`protected int` | `count` Deprecated. The number of valid characters in the input stream buffer.
`protected int` | `pos` Deprecated. The index of the next character to read from the input stream buffer.

Constructor Summary
`StringBufferInputStream(String s)` Deprecated. Creates a string input stream to read data from the specified string.

Method Summary
`int` | `available()` Deprecated. Returns the number of bytes that can be read from the input stream without blocking.
`int` | `read()` Deprecated. Reads the next byte of data from this input stream.
`int` | `read(byte[] b, int off, int len)` Deprecated. Reads up to `len` bytes of data from this input stream into an array of bytes.
`void` | `reset()` Deprecated. Resets the input stream to begin reading from the first character of this input stream's underlying buffer.
`long` | `skip(long n)` Deprecated. Skips `n` bytes of input from this input stream.

Field Detail

### buffer

    protected String buffer

  Deprecated.
  The string from which bytes are read.

### pos

    protected int pos

  Deprecated.
  The index of the next character to read from the input stream buffer.

  See Also:
    `buffer`

### count

    protected int count

  Deprecated.
  The number of valid characters in the input stream buffer.

  See Also:
    `buffer`

Constructor Detail

### StringBufferInputStream

    public StringBufferInputStream(String s)

  Deprecated.
  Creates a string input stream to read data from the specified string.

  Parameters:
    `s` - the underlying input buffer.

Method Detail

### read

    public int read()

  Deprecated.
  Reads the next byte of data from this input stream. The value byte is returned as an `int` in the range `0` to `255`. If no byte is available because the end of the stream has been reached, the value `-1` is returned.

  The `read` method of `StringBufferInputStream` cannot block. It returns the low eight bits of the next character in this input stream's buffer.

  Specified by:
    `read` in class `InputStream`
  Returns:
    the next byte of data, or `-1` if the end of the stream is reached.

### read

    public int read(byte[] b,
                    int off,
                    int len)

  Deprecated.
  Reads up to `len` bytes of data from this input stream into an array of bytes.

  The `read` method of `StringBufferInputStream` cannot block. It copies the low eight bits from the characters in this input stream's buffer into the byte array argument.

  Overrides:
    `read` in class `InputStream`
  Parameters:
    `b` - the buffer into which the data is read.
    `off` - the start offset of the data.
    `len` - the maximum number of bytes read.
  Returns:
    the total number of bytes read into the buffer, or `-1` if there is no more data because the end of the stream has been reached.
  See Also:
    `InputStream.read()`

### skip

    public long skip(long n)

  Deprecated.
  Skips `n` bytes of input from this input stream. Fewer bytes might be skipped if the end of the input stream is reached.

  Overrides:
    `skip` in class `InputStream`
  Parameters:
    `n` - the number of bytes to be skipped.
  Returns:
    the actual number of bytes skipped.

### available

    public int available()

  Deprecated.
  Returns the number of bytes that can be read from the input stream without blocking.

  Overrides:
    `available` in class `InputStream`
  Returns:
    the value of `count - pos`, which is the number of bytes remaining to be read from the input buffer.

### reset

    public void reset()

  Deprecated.
  Resets the input stream to begin reading from the first character of this input stream's underlying buffer.

  Overrides:
    `reset` in class `InputStream`
  See Also:
    `InputStream.mark(int)`, `IOException`
