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
See Also:
  • ByteArrayInputStream
  • StringReader

Creates a string input stream to read data from the specified string.

Method Summary

Modifier and Type Method Description
int available()
Deprecated.
Returns the number of bytes that can be read from the input stream without blocking.
int read()
Deprecated.
Reads the next byte of data from this input stream.
int read(byte[] b, int off, int len)
Deprecated.

Methods declared in class InputStream

Modifier and Type Method Description
void close()
Closes this input stream and releases any system resources associated with the stream.
void mark(int readlimit)
Marks the current position in this input stream.
boolean markSupported()
Tests if this input stream supports the mark and reset methods.
static InputStream nullInputStream()
Returns a new InputStream that reads no bytes.
int read(byte[] b)
Reads some number of bytes from the input stream and stores them into the buffer array b.
byte[] readAllBytes()

Reads up to a specified number of bytes from the input stream.
void skipNBytes(long n)
Skips over and discards exactly n bytes of data from this input stream.
long transferTo(OutputStream out)
Reads all bytes from this input stream and writes the bytes to the given output stream in the order that they are read.

Modifier and Type Method Description
protected Object clone()
Creates and returns a copy of this object.
boolean equals(Object obj)

String toString()
Returns a string representation of the object.
final void wait()
Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
final void wait(long timeoutMillis)
Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
final void wait(long timeoutMillis, int nanos)
Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Field Details

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.
See Also:
  • buffer

count

protected int count
Deprecated.
The number of valid characters in the input stream buffer.
See Also:
  • 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.
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.
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
