readByteBuffer

public static void readByteBuffer(ByteBuffer buffer,
                                  FileChannel channel,
                                  long position,
                                  boolean throwOnEof)
                           throws IOException

Reads data from FileChannel to ByteBuffer starting from passed in position in FileChannel. Data will be read to ByteBuffer starting from current position till buffer limit.

This method is thread safe in sense that several threads can read from the same FileChannel.

Parameters:

throwOnEof - If parameter set to true then EOF exception will be thrown if end of file will be reached otherwise buffer will be filled with 0 bytes.

Throws:

IOException

readByteBuffer

public static void readByteBuffer(ByteBuffer buffer,
                                  FileChannel channel)
                           throws IOException

Reads data from FileChannel to ByteBuffer starting from current position in FileChannel. Data will be read to ByteBuffer since the start of the buffer till buffer limit.

This method is not thread safe, several threads can not read from the same channel.

Throws:

IOException

writeByteBuffer

public static void writeByteBuffer(ByteBuffer buffer,
                                   FileChannel channel,
                                   long position)
                            throws IOException

Writes data from ByteBuffer to FileChannel starting from passed in FileChannel position. Data will be written since the start of the buffer till buffer limit.

This method is thread safe in the sense that several threads can write to single FileChannel.

Throws:

IOException

writeByteBuffers

public static void writeByteBuffers(ByteBuffer[] buffers,
                                    FileChannel channel,
                                    long bytesToWrite)
                             throws IOException

Writes content of passed in buffers into FileChannel since current channels position till at least passed in limit of bytes.

All buffers content will be written starting from their zero position.

This method is not thread safe, many threads can not write into single channel.

Parameters:

bytesToWrite - Minimum amount of bytes which should be written to channel

Throws:

IOException

readByteBuffers

public static void readByteBuffers(ByteBuffer[] buffers,
                                   FileChannel channel,
                                   long bytesToRead,
                                   boolean throwOnEof)
                            throws IOException

Reads from FileChannel current position to array of ByteBuffers continues chunk of data till at least provided limit of bytes will be written.

Data will be loaded into buffers since zero position.

This methods is not thread safe, several threads can not read from the same channel.

Parameters:

bytesToRead - Minimum amount of bytes which should be read from channel.

throwOnEof - if flag is set to true EOF exception will be thrown, otherwise end of buffers will be filled by zeros.

Throws:

IOException
