Class StringBufferInputStream

java.lang.Object
java.io.InputStream
java.io.StringBufferInputStream
All Implemented Interfaces:
Closeable, AutoCloseable
@Deprecated public class StringBufferInputStream extends InputStream
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.
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.

1.0

    • 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 Details

    • 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.
      Specified by:
      read in class InputStream
      Implementation Requirements:
      The read method of StringBufferInputStream cannot block. It returns the low eight bits of the next character in this input stream's buffer.
      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.
      Overrides:
      read in class InputStream
      Implementation Requirements:
      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.
      Parameters:
      b - the buffer into which the data is read.
      off - the start offset in array b at which the data is written.
      len - the maximum number of bytes to 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.

    • 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.
      See Also:

    • 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
