Public Methods
public int available()
Answers a int representing then number of bytes that are available before
this InputStream will block. This method always returns 0. Subclasses
should override and indicate the correct number of bytes available.
Throws
| IOException |
|---|
public void close()
Close the InputStream. Concrete implementations of this class should free
any resources during close. This implementation does nothing.
Throws
| IOException |
|---|
public AudioFormat getFormat()
public long getFrameLength()
public void mark(int readlimit)
Set a Mark position in this InputStream. The parameter
readLimit indicates how many bytes can be read before a
mark is invalidated. Sending reset() will reposition the Stream back to
the marked position provided readLimit has not been
surpassed.
This default implementation does nothing and concrete subclasses must provide their own implementations.
Parameters
| readlimit | the number of bytes to be able to read before invalidating the mark. |
|---|
public boolean markSupported()
Answers a boolean indicating whether or not this InputStream supports
mark() and reset(). This class provides a default implementation which
answers false.
public int read(byte[] b, int off, int len)
Reads at most
length bytes from the Stream and stores them
in byte array b starting at offset. Answer
the number of bytes actually read or -1 if no bytes were read and end of
stream was encountered.
Parameters
| b | the byte array in which to store the read bytes. |
|---|---|
| off | the offset in b to store the read bytes. |
| len | the maximum number of bytes to store in b. |
Throws
| IOException |
|---|
public int read(byte[] b)
Reads bytes from the Stream and stores them in byte array
b.
Answer the number of bytes actually read or -1 if no bytes were read and
end of stream was encountered.
Parameters
| b | the byte array in which to store the read bytes. |
|---|
Throws
| IOException |
|---|
public int read()
Reads a single byte from this InputStream and returns the result as an
int. The low-order byte is returned or -1 of the end of stream was
encountered. This abstract implementation must be provided by concrete
subclasses.
Throws
| IOException |
|---|
public void reset()
Reset this InputStream to the last marked location. If the
readlimit has been passed or no mark has
been set, throw IOException. This implementation throws IOException and
concrete subclasses should provide proper implementations.
Throws
| IOException |
|---|
public long skip(long n)
Skips
n number of bytes in this InputStream. Subsequent
read()'s will not return these bytes unless
reset() is used. This method may perform multiple reads to
read n bytes. This default implementation reads
n bytes into a temporary buffer. Concrete subclasses
should provide their own implementation.
Parameters
| n | the number of bytes to skip. |
|---|
Throws
| IOException |
|---|
