StringBufferInputStream JDK 1.6)

Methods

publicsynchronized int available () [Overrides InputStream]

Returns the number of bytes that can be read from the input stream without blocking.

Returns the number of bytes that can be read from the input
stream without blocking.
Returns: the value of count - pos, which is the number of bytes remaining to be read from the input buffer.

public void close () throws IOException [Inherited From InputStream]

Closes this input stream and releases any system resources associated with the stream.

publicsynchronized void mark (int readlimit) [Inherited From InputStream]

Marks the current position in this input stream.

Marks the current position in this input stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.

The readlimit arguments tells this input stream to allow that many bytes to be read before the mark position gets invalidated.

The general contract of mark is that, if the method markSupported returns true, the stream somehow remembers all the bytes read after the call to mark and stands ready to supply those same bytes again if and whenever the method reset is called. However, the stream is not required to remember any data at all if more than readlimit bytes are read from the stream before reset is called.

Marking a closed stream should not have any effect on the stream.

The mark method of InputStream does nothing.
Parameters:
- readlimit - the maximum limit of bytes that can be read before the mark position becomes invalid.
See Also: InputStream.reset(),

public boolean markSupported () [Inherited From InputStream]

Tests if this input stream supports the mark and reset methods.

Tests if this input stream supports the mark and
reset methods. Whether or not mark and
reset are supported is an invariant property of a
particular input stream instance. The markSupported method
of InputStream returns false.
Returns: true if this stream instance supports the mark and reset methods; false otherwise.
See Also: InputStream.mark(int), InputStream.reset(),

publicsynchronized int read () [Specified in InputStream]

Reads the next byte of data from this input stream.

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.
Returns: the next byte of data, or -1 if the end of the stream is reached.

public int read (byte[] b) throws IOException [Inherited From InputStream]

Reads some number of bytes from the input stream and stores them into the buffer array b.

Reads some number of bytes from the input stream and stores them into the buffer array b. The number of bytes actually read is returned as an integer. This method blocks until input data is available, end of file is detected, or an exception is thrown.

If the length of b is zero, then no bytes are read and 0 is returned; otherwise, there is an attempt to read at least one byte. If no byte is available because the stream is at the end of the file, the value -1 is returned; otherwise, at least one byte is read and stored into b.

The first byte read is stored into element b[0], the next one into b[1], and so on. The number of bytes read is, at most, equal to the length of b. Let k be the number of bytes actually read; these bytes will be stored in elements b[0] through b[k-1], leaving elements b[k] through b[b.length-1] unaffected.

The read(b) method for class InputStream has the same effect as:

 read(b, 0, b.length)

Returns: the total number of bytes read into the buffer, or -1 is there is no more data because the end of the stream has been reached.
Parameters:
- b - the buffer into which the data is read.
Throws:
- IOException - If the first byte cannot be read for any reason other than the end of the file, if the input stream has been closed, or if some other I/O error occurs.
- NullPointerException - if b is null.
See Also: InputStream.read(byte[], int, int),

publicsynchronized int read (byte[] b, int off, int len) [Overrides InputStream]

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.
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.
Parameters:
- b - the buffer into which the data is read.
- off - the start offset of the data.
- len - the maximum number of bytes read.

publicsynchronized void reset () [Overrides InputStream]

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

publicsynchronized long skip (long n) [Overrides InputStream]

Skips n bytes of input from this input stream.

Skips n bytes of input from this input stream. Fewer
bytes might be skipped if the end of the input stream is reached.
Returns: the actual number of bytes skipped.
Parameters:
- n - the number of bytes to be skipped.
