Constructor Details

PairedEmuFileContents

public PairedEmuFileContents(EmuFileContents<L> left,
 EmuFileContents<R> right)

Create a paired file contents

Parameters:

left - the left contents

right - the right contents

Method Details

read

public long read(long offset,
 org.apache.commons.lang3.tuple.Pair<L,R> buf,
 long fileSize)

Description copied from interface: EmuFileContents

Copy values from the file into the given buffer

Specified by:

read in interface EmuFileContents<L>

Parameters:

offset - the offset in the file to read

buf - the destination buffer, whose size must be known

fileSize - the size of the file

Returns:

the number of bytes (not necessarily concrete) read

write

public long write(long offset,
 org.apache.commons.lang3.tuple.Pair<L,R> buf,
 long curSize)

Description copied from interface: EmuFileContents

Write values from the given buffer into the file

Specified by:

write in interface EmuFileContents<L>

Parameters:

offset - the offset in the file to write

buf - the source buffer, whose size must be known

curSize - the current size of the file

Returns:

the number of bytes (not necessarily concrete) written

truncate

public void truncate()

Description copied from interface: EmuFileContents

Erase the contents

Note that the file's size will be set to 0, so actual erasure of the contents may not be necessary, but if the contents are expensive to store, they ought to be disposed.

Specified by:

truncate in interface EmuFileContents<L>
