从接口复制的说明: DataInputView

Skips numBytes bytes of memory. In contrast to the DataInput.skipBytes(int) method, this method always skips the desired number of bytes or throws an EOFException.

指定者:

skipBytesToRead 在接口中 DataInputView

参数:

numBytes - The number of bytes to skip.

抛出:

IOException - Thrown, if any I/O related problem occurred such that the input could not be advanced to the desired position.

read

                int len)
         throws IOException

从接口复制的说明: DataInputView

Reads up to len bytes of memory and stores it into b starting at offset off. It returns the number of read bytes or -1 if there is no more data left.

指定者:

read 在接口中 DataInputView

参数:

b - byte array to store the data to

off - offset into byte array

len - byte length to read

返回:

the number of actually read bytes of -1 if there is no more data left

抛出:

IOException

read

public int read(@Nonnull
                byte[] b)
         throws IOException

指定者:

read 在接口中 DataInputView

参数:

b - byte array to store the data to

返回:

the number of read bytes or -1 if there is no more data left

抛出:

IOException

getPosition

public int getPosition()
