StringBufferInputStream (Java Platform SE 7 ) (original) (raw)

• java.lang.Object

• • java.io.InputStream
  • • java.io.StringBufferInputStream

• 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 aByteArrayInputStream.
Only the low eight bits of each character in the string are used by this class.
Since:
JDK1.0
See Also:
ByteArrayInputStream, StringReader

• • Field Detail

     * #### buffer  
     protected [String](../../java/lang/String.html "class in java.lang") 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.

     [buffer](../../java/io/StringBufferInputStream.html#buffer)  
     * #### count  
     protected int count  
     Deprecated.  
     The number of valid characters in the input stream buffer.  
     See Also:  
     [buffer](../../java/io/StringBufferInputStream.html#buffer)  

  • Constructor Detail

    * #### StringBufferInputStream  
    public StringBufferInputStream([String](../../java/lang/String.html "class in java.lang") 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](../../java/io/InputStream.html#read%28%29)` in class `[InputStream](../../java/io/InputStream.html "class in java.io")`  
    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](../../java/io/InputStream.html#read%28byte[],%20int,%20int%29)` in class `[InputStream](../../java/io/InputStream.html "class in java.io")`  
    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()](../../java/io/InputStream.html#read%28%29)  
    * #### 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](../../java/io/InputStream.html#skip%28long%29)` in class `[InputStream](../../java/io/InputStream.html "class in java.io")`  
    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](../../java/io/InputStream.html#available%28%29)` in class `[InputStream](../../java/io/InputStream.html "class in java.io")`  
    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](../../java/io/InputStream.html#reset%28%29)` in class `[InputStream](../../java/io/InputStream.html "class in java.io")`  
    See Also:
