public interface InputStreaming
This is the interface represented by the Java InputStream class.
Method Summary | |
---|---|
int |
available() Returns the number of bytes that can be read (or skipped over) from this input stream without causing a blocking I/O condition to occur. |
void |
close() Close the InputStream and release any system resources associated with it. |
void |
mark(int cbReadLimit) Marks the current read position in the InputStream in order to support the stream to be later "rewound" (using the reset() method) to the current position. |
boolean |
markSupported() Determine if this InputStream supports the mark(int) and reset() methods. |
int |
read() Read the next byte of data from the InputStream. |
int |
read(byte[] ab) Read some number of bytes from the input stream and store them into the passed array ab . |
int |
read(byte[] ab, int of, int cb) Read up to cb bytes from the input stream and store them into the passed array ab starting at offset of . |
void |
reset() Rewind this stream to the position at the time the mark(int) method was last called on this InputStream. |
long |
skip(long cb) Skips over up to the specified number of bytes of data from this InputStream. |

int read() throws java.io.IOException
int
in the range 0
to 255
. If 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.

. The number of bytes actually read is returned.
This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

if no bytes were read from the stream because the end of the stream had been reachedjava.lang.NullPointerException

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

method, thus indicating the upper bounds of the responsibility of the stream to be able to buffer what it has read in order to support this functionality.cbReadLimit
