Constructor Detail

GrappaPoint

public GrappaPoint()

Constructs and initializes a GrappaPoint with coordinates (0, 0).

GrappaPoint

public GrappaPoint(double x,
                   double y)

Constructs and initializes a GrappaPoint with the specified coordinates.

Parameters:

x, y - the coordinates to which to set the newly constructed GrappaPoint

GrappaPoint

public GrappaPoint(java.lang.String coordString)

Constructs and initializes a GrappaPoint with the coordinates derived from the specified String representation. The String format should be: "x-coord,y-coord"

Parameters:

coordString - String representing the coordinates to which to set the newly constructed GrappaPoint

Method Detail

toAttributeString

public java.lang.String toAttributeString()

Returns:

attribute-suitable string representation of this GrappaPoint.

toFormattedString

public java.lang.String toFormattedString(java.lang.String format)

Provides a formatted string representation of this object.

Parameters:

format - the format used to build the string (%p is the base directive for a GrappaPoint).

Returns:

a string representation of this GrappaPoint.

toString

public java.lang.String toString()

Provides a generic string representation of this object.

Overrides:

toString in class java.awt.geom.Point2D.Double

Returns:

a generic string representation of this GrappaPoint.
