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.

Since:
1.0

    • 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.

  • Constructor Details

    • 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.

      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.
      See Also:
      InputStream.skipNBytes(long)

    • 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
