Class StringBufferInputStream

Table des matières
  • All Implemented Interfaces:
    Closeable, AutoCloseable
    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

      • 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.

      • count

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

        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.
