MUS

public MUS()

Creates a blank MUS lump with no events.

Method Details

getPrimaryChannelCount

public int getPrimaryChannelCount()

Returns:

the amount of primary channels (from channel 0).

getSecondaryChannelCount

public int getSecondaryChannelCount()

Returns:

the amount of secondary channels (from channel 10).

getInstrumentPatchCount

public int getInstrumentPatchCount()

Returns:

the amount of instrument patches.

getInstrumentPatch

public int getInstrumentPatch(int index)

Gets an instrument patch to preload.

Parameters:

index - the instrument patch list index.

Returns:

the instrument at the corresponding index.

iterator

public Iterator<MUS.Event> iterator()

Specified by:

iterator in interface Iterable<MUS.Event>

readBytes

public void readBytes(InputStream in)
               throws IOException

Description copied from interface: BinaryObject

Reads from an InputStream and sets this object's fields. Only reads the amount of bytes that it takes to read a single instance of the object. Note that not every object may have a consistent length!

Specified by:

readBytes in interface BinaryObject

Parameters:

in - the InputStream to read from.

Throws:

IOException - if a read error occurs.

writeBytes

public void writeBytes(OutputStream out)
                throws IOException

Description copied from interface: BinaryObject

Writes this object to an OutputStream.

Specified by:

writeBytes in interface BinaryObject

Parameters:

out - the OutputStream to write to.

Throws:

IOException - if a write error occurs.
