Interface IlvVMAPDataInput

public interface IlvVMAPDataInput

The interface that a stream must implement to provide VMAP data.

Since:

JViews 8.1

Version:

1.0

Method Summary

Modifier and Type	Method and Description
void	close() Closes this input stream and releases any system resources associated with the stream.
int	read() Reads the next byte of data from the input stream.
int	read(byte[] b, int off, int len) Reads up to len bytes of data from the input stream into an array of bytes.
void	seek(long pos) Sets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs.

Method Detail

read

int read()
  throws IOException

Reads the next byte of data from the input stream.

Returns:

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

Throws:

IOException

read

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

Reads up to len bytes of data from the input stream into an array of bytes.

Parameters:

b - The buffer into which the data is read.

off - The start offset in array b at which the data is written.

len - The maximum number of bytes to read.

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.

Throws:

IOException

close

void close()
    throws IOException

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

Throws:

IOException

seek

void seek(long pos)
   throws IOException

Sets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs. The offset may be set beyond the end of the file. Setting the offset beyond the end of the file does not change the file length. The file length will change only by writing after the offset has been set beyond the end of the file.

Parameters:

pos - The offset position, measured in bytes from the beginning of the file, at which to set the file pointer.

Throws:

IOException
