Constructor Details

MMidPoint

protected MMidPoint(MPolyline l,
 int i,
 double x,
 double y,
 double z)

Contructs a middle point object.

Parameters:

l - the parent polyline

i - polyline point index

x - the x coordinate

y - the y coordinate

z - the z coordinate

MMidPoint

protected MMidPoint(MMidPoint p)

Copy constructor.

Parameters:

p - the point

Method Details

hashCode

public int hashCode()

Overrides:

hashCode in class MPoint

equals

public boolean equals(Object o)

Two midpoints equal if their parent lines are the same and the polyline point indices also equal.

Overrides:

equals in class MPoint

Parameters:

o - the other point

Returns:

true if they equal, false otherwise

clone

public MMidPoint clone()

Description copied from class: MObject

Creates a clone.

Overrides:

clone in class MPoint

Returns:

the clone

isSelectableNow

public boolean isSelectableNow()

Description copied from class: MObject

Is the object selectable now?

Overrides:

isSelectableNow in class MObject

Returns:

true for ordinary objects, false for some internal selectables

isChildOf

public boolean isChildOf(MObject o)

Is this object a children of another one?

Overrides:

isChildOf in class MPoint

Parameters:

o - a possible parent

Returns:

true if the other object is the parent line, false otherwise

getPositionInPolyline

public int getPositionInPolyline()

Gets the position in the polyline.

Returns:

the position

getParentLine

public MPolyline getParentLine()

Gets the parent line.

Returns:

the parent line

addNotify

public void addNotify(MDocument doc)

Point added to a document.

Overrides:

addNotify in class MObject

Parameters:

doc - The document the object is being added to.

removeNotify

public void removeNotify(MDocument doc)

Point removed from a document.

Overrides:

removeNotify in class MObject

Parameters:

doc - The document from which the object is removed.

getLocation

public void getLocation(DPoint3 q,
 CTransform3D t)

Gets the location.

Overrides:

getLocation in class MPoint

Parameters:

q - the output point object

t - the transformation matrix or null

getFixedLocation

protected void getFixedLocation(DPoint3 q,
 CTransform3D t)

Gets the fixed location in the polyline.

Parameters:

q - the output point object

t - the transformation matrix or null

setLocation

public void setLocation(DPoint3 p,
 CTransform3D trot)

Sets the location

Overrides:

setLocation in class MPoint

Parameters:

p - the new location

trot - the viewing transformation or null

transform

public void transform(CTransform3D t,
 int opts,
 CTransform3D trot)

Transforms all points.

Overrides:

transform in class MPoint

Parameters:

t - the transformation matrix

opts - the transform options

trot - the viewing transformation or null

• MObject.TRANSFORM_DISTORT

toString

public String toString()

Overrides Object.toString() to ease debugging. Returns a string consisting of the classname (without the package name!), the at-sign character `@', the unsigned hexadecimal representation of the hash code of the object and location information in square brackets. The location information consists of the parent polyline's toString representation and the section index, separated by a comma.

Overrides:

toString in class MPoint

Returns:

a string representation of the object
