Constructor Details

RandomAccessFileReader

public RandomAccessFileReader(RandomAccessFile file)
                       throws IOException

Deprecated.

Throws:

IOException

RandomAccessFileReader

public RandomAccessFileReader(RandomAccessFile file,
 int baseOffset)
                       throws IOException

Deprecated.

Throws:

IOException

Method Details

toUnshiftedOffset

public int toUnshiftedOffset(int localOffset)

Deprecated.

Specified by:

toUnshiftedOffset in class RandomAccessReader

getLength

public long getLength()

Deprecated.

Description copied from class: RandomAccessReader

Returns the length of the data source in bytes.

This is a simple operation for implementations (such as RandomAccessFileReader and ByteArrayReader) that have the entire data source available.

Users of this method must be aware that sequentially accessed implementations such as RandomAccessStreamReader will have to read and buffer the entire data source in order to determine the length.

Specified by:

getLength in class RandomAccessReader

Returns:

the length of the data source, in bytes.

getByte

public byte getByte(int index)
             throws IOException

Deprecated.

Description copied from class: RandomAccessReader

Gets the byte value at the specified byte index.

Implementations should not perform any bounds checking in this method. That should be performed in validateIndex and isValidIndex.

Specified by:

getByte in class RandomAccessReader

Parameters:

index - The index from which to read the byte

Returns:

The read byte value

Throws:

IOException - if the byte is unable to be read

getBytes

public byte[] getBytes(int index,
 int count)
                throws IOException

Deprecated.

Description copied from class: RandomAccessReader

Returns the required number of bytes from the specified index from the underlying source.

Specified by:

getBytes in class RandomAccessReader

Parameters:

index - The index from which the bytes begins in the underlying source

count - The number of bytes to be returned

Returns:

The requested bytes

Throws:

IOException - if the byte is unable to be read
