Class MSplitter.Result

java.lang.Object

eu.bandm.music.entities.MSplitter.Result

Enclosing class:

MSplitter

public class MSplitter.Result
extends Object

Represents one result of processing a sequence of qualified durations. It contains a set of all nodes which must be printed, and, for convenience, a map from each such node to the total duration which it must represent.

Modifier and Type	Class and Description
class	MSplitter.Result.WriteOut This local class performs serialization of a rhythm representation, including the opening and closing of n-plet-brackets in a minimal fashion.

Field Summary

Fields

Modifier and Type	Field and Description
protected Set<MTree>	additionalProportions Recognized dotted structures which possibly require an additional proportion.
protected List<QualifiedRational>	eventStarts The original input to the splitter process.
protected List<List<MTree>>	initialCoverage The intermediately calculated IC.
protected Set<MTree>	printed The result: Set of the nodes, the start points of which carry a note symbol.
protected Map<MTree,StemEnd>	stemEnds The beams of the printed note symbols.
protected Map<MTree,Rational>	summedDuration Convenience cache: The duration represented by the printed note symbols coming from MXs=merging transformations.
protected Map<MTree,RationalDuration.DottedBaseDuration>	symbols Cache for the note symbols for results of merging = for a node which has eaten some of its followers.

Field Detail

eventStarts

protected final List<QualifiedRational> eventStarts

The original input to the splitter process.

initialCoverage

protected List<List<MTree>> initialCoverage

The intermediately calculated IC.

printed

protected final Set<MTree> printed

The result: Set of the nodes, the start points of which carry a note symbol.

summedDuration

protected final Map<MTree,Rational> summedDuration

Convenience cache: The duration represented by the printed note symbols coming from MXs=merging transformations.

stemEnds

protected final Map<MTree,StemEnd> stemEnds

The beams of the printed note symbols.

symbols

protected final Map<MTree,RationalDuration.DottedBaseDuration> symbols

Cache for the note symbols for results of merging = for a node which has eaten some of its followers. Only one entry for sound and pauses (only one of them is in each Result).

additionalProportions

protected final Set<MTree> additionalProportions

Recognized dotted structures which possibly require an additional proportion. The first node is memorized here. FIXME NOT YET SUPPORTED

Constructor Detail

Result

public Result(List<QualifiedRational> eventStarts)

Construct an instance with all result fields not yet set.

Method Detail

getStemEnd

protected StemEnd getStemEnd(MTree node)

Get the stem end (left and right long and short beams) for the given node.

sumUp

protected void sumUp()

Add the durations of all nodes not being printed to their predecessor. A node appears as a key in summedDuration only if it the result of a merging transformation. So it holds that "domain(summedDuration) subsetEq printed". Create a new StemEnd for the printed node, if necessary. (The sum values are somehow redundant and only for the convenience of the caller.)

dump

public void dump()

Printing method for debugging and demonstration.

get_InitialCoverage

public List<List<MTree>> get_InitialCoverage()

Return the initial coverage calculated during the msplit process.
