public class KeySignature

extends MusicSymbol

A KeySignature has a standard code indicating the number of sharps or flats

Field Summary

_tags

Constructor Summary

KeySignature(int standardCode, Tags tags)
Creates a new KeySignature with the given parameters.

Method Summary

void	draw(java.awt.Graphics graphics) Draw this object
FinalPoint	getScreenHotspot() Get the hotspot for this object in screen coordinates.
int	getStandardCode() Returns the standard code indicating the number of sharps or flats: 0 = no sharps or flats, 1-7 =1-7 sharps, 8-14 = 1-7 flats, -1 - -7 = 1-7 naturals in the sharp positions, -8 - -14 = 1-7 naturals in the flat positions
void	invalidate() This is automatically called after the object is modified to force this to recompute all its values when the "get" method is called for the value.
boolean	isLeftPositionedSymbol() Return true if this is a symbol, like a cleff change, which appears to the left of the main symbol in the time slice, like the stem.

Constructor Detail

KeySignature

public KeySignature(int standardCode,
                    Tags tags)

Creates a new KeySignature with the given parameters.

Parameters:

standardCode - see getStandardCode()

tags - the tags for this music symbol. If this is null, then this uses an empty Tags object.

Method Detail

getStandardCode

public int getStandardCode()

Returns the standard code indicating the number of sharps or flats: 0 = no sharps or flats, 1-7 =1-7 sharps, 8-14 = 1-7 flats, -1 - -7 = 1-7 naturals in the sharp positions, -8 - -14 = 1-7 naturals in the flat positions

invalidate

public void invalidate()

This is automatically called after the object is modified to force this to recompute all its values when the "get" method is called for the value.

Overrides:

invalidate in class MusicSymbol

getScreenHotspot

public FinalPoint getScreenHotspot()

Get the hotspot for this object in screen coordinates.

Specified by:

getScreenHotspot in interface Anchored

Overrides:

getScreenHotspot in class MusicSymbol

Returns:

The position of the hotspot in screen coordinates from top-left of screen (not relative to an anchor). This is a FinalPoint and not a Point so that the class can give access to its screen hotspot object knowing that the caller will not modify it. This is more efficient that returning a new Point every time getScreenHotspot() is called.

See Also:

FinalPoint.newPoint()

draw

public void draw(java.awt.Graphics graphics)

Draw this object

Overrides:

draw in class MusicSymbol

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

isLeftPositionedSymbol

public boolean isLeftPositionedSymbol()

Description copied from class: MusicSymbol

Return true if this is a symbol, like a cleff change, which appears to the left of the main symbol in the time slice, like the stem. The default return value is false but Cleff, TimeSignature, etc. should override and return true.

Overrides:

isLeftPositionedSymbol in class MusicSymbol
