| Modifier and Type | Method and Description |
|---|---|
void |
close()
Closes this input stream and releases any system resources
associated with the stream.
|
boolean |
isClosed()
Returns, whether this stream is already closed.
|
protected abstract void |
raiseError(long pSizeMax,
long pCount)
Called to indicate, that the input streams limit has
been exceeded.
|
int |
read()
Reads the next byte of data from this input stream.
|
int |
read(byte[] b,
int off,
int len)
Reads up to
len bytes of data from this input stream
into an array of bytes. |

inputStream - The input stream, which shall be limited.pSizeMax - The limit; no more than this number of bytes
shall be returned by the source stream.protected abstract void raiseError(long pSizeMax,
long pCount)
throws java.io.IOException
pSizeMax - The input streams limit, in bytes.pCount - The actual number of bytes.java.io.IOException - The called method is expected
to raise an IOException.public int read()
throws java.io.IOException
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.
This method
simply performs in.read() and returns the result.

int off,
int len)
throws java.io.IOException
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.
This method simply performs in.read(b, off, len)
and returns the result.
