Method Detail

available	back to summary
public int available() throws IOException Overrides java.io.FilterInputStream.available. Doc from java.io.FilterInputStream.available. Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes. Returns:int an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking. Exceptions IOException: if an I/O error occurs.

public int available() throws IOException

Overrides java.io.FilterInputStream.available.

Doc from java.io.FilterInputStream.available.

Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes.

Returns:int

an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking.

Exceptions

IOException:: if an I/O error occurs.

mark back to summary

mark	back to summary
public synchronized void mark(int readlimit) Overrides java.io.FilterInputStream.mark. Doc from java.io.FilterInputStream.mark. 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` argument tells this input stream to allow that many bytes to be read before the mark position gets invalidated. Parameters readlimit:int the maximum limit of bytes that can be read before the mark position becomes invalid.

public synchronized void mark(int readlimit)

Overrides java.io.FilterInputStream.mark.

Doc from java.io.FilterInputStream.mark.

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

Parameters

readlimit:int: the maximum limit of bytes that can be read before the mark position becomes invalid.

markSupported back to summary

markSupported	back to summary
public boolean markSupported() Overrides java.io.FilterInputStream.markSupported. Doc from java.io.FilterInputStream.markSupported. Tests if this input stream supports the `mark` and `reset` methods. Returns:boolean `true` if this stream type supports the `mark` and `reset` method; `false` otherwise.

public boolean markSupported()

Overrides java.io.FilterInputStream.markSupported.

Doc from java.io.FilterInputStream.markSupported.

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

Returns:boolean: true if this stream type supports the mark and reset method; false otherwise.

read back to summary

read	back to summary
public int read() throws IOException Overrides java.io.FilterInputStream.read. Doc from java.io.FilterInputStream.read. Reads the next byte of data from the 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. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown. Returns:int the next byte of data, or `-1` if the end of the stream is reached. Exceptions IOException: if an I/O error occurs.

public int read() throws IOException

Overrides java.io.FilterInputStream.read.

Doc from java.io.FilterInputStream.read.

Reads the next byte of data from the 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. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Returns:int

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

Exceptions

IOException:: if an I/O error occurs.

read back to summary

read	back to summary
public int read(byte[] b, int off, int len) throws IOException Overrides java.io.FilterInputStream.read. Doc from java.io.FilterInputStream.read. Reads up to `len` bytes of data from this input stream into an array of bytes. If `len` is not zero, the method blocks until some input is available; otherwise, no bytes are read and `0` is returned. Parameters b:byte[] the buffer into which the data is read. off:int the start offset in array `b` at which the data is written. len:int the maximum number of bytes to read. Returns:int 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. Exceptions IOException: if an I/O error occurs.

public int read(byte[] b, int off, int len) throws IOException

Overrides java.io.FilterInputStream.read.

Doc from java.io.FilterInputStream.read.

Reads up to len bytes of data from this input stream into an array of bytes. If len is not zero, the method blocks until some input is available; otherwise, no bytes are read and 0 is returned.

Parameters

b:byte[]: the buffer into which the data is read.
off:int: the start offset in array b at which the data is written.
len:int: the maximum number of bytes to read.

Returns:int

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.

Exceptions

IOException:: if an I/O error occurs.

readHeader	back to summary
public void readHeader() throws IOException

reset back to summary

reset	back to summary
public synchronized void reset() throws IOException Overrides java.io.FilterInputStream.reset. Doc from java.io.FilterInputStream.reset. Repositions this stream to the position at the time the `mark` method was last called on this input stream. Stream marks are intended to be used in situations where you need to read ahead a little to see what's in the stream. Often this is most easily done by invoking some general parser. If the stream is of the type handled by the parse, it just chugs along happily. If the stream is not of that type, the parser should toss an exception when it fails. If this happens within readlimit bytes, it allows the outer code to reset the stream and try another parser. Exceptions IOException: if this stream has not been marked or if the mark has been invalidated.

public synchronized void reset() throws IOException

Overrides java.io.FilterInputStream.reset.

Doc from java.io.FilterInputStream.reset.

skip back to summary

skip	back to summary
public long skip(long n) throws IOException Overrides java.io.FilterInputStream.skip. Doc from java.io.FilterInputStream.skip. Skips over and discards `n` bytes of data from the input stream. The `skip` method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly `0`. The actual number of bytes skipped is returned. Parameters n:long the number of bytes to be skipped. Returns:long the actual number of bytes skipped. Exceptions IOException: if `in.skip(n)` throws an IOException.

public long skip(long n) throws IOException

Overrides java.io.FilterInputStream.skip.

Doc from java.io.FilterInputStream.skip.

Skips over and discards n bytes of data from the input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned.

Parameters

n:long: the number of bytes to be skipped.

Returns:long

the actual number of bytes skipped.

Exceptions

IOException:: if in.skip(n) throws an IOException.
