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.

public class StringBufferInputStream

extends InputStream

Untamed: 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

Constructor Detail

StringBufferInputStream

public StringBufferInputStream(String s)

Deprecated.

Enabled: 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.

Enabled: 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.

Enabled: 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:

java.io.InputStream#read()

skip

public long skip(long n)

Deprecated.

Enabled: 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.

Enabled: 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.

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

Overrides:

reset in class InputStream
