Detailed Description
Points are the most straightforward geometries to define, and therefore the Point type and this builder have the same properties. This builder type is provided mainly for consistency with other immutable geometries.
The spatial reference must be set before using the builder and cannot be changed after the builder contains points.
This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
| Type | Default Property |
|---|---|
| SpatialReference | spatialReference |
Property Documentation
m : double |
The m-value.
x : double |
The x-coordinate.
y : double |
The y-coordinate.
z : double |
The z-coordinate.
The minimum z-value is -6,356,752 meters, which is the approximate radius of the earth (the WGS 84 datum semi-minor axis). The maximum z-value is 55,000,000 meters.
Signal Documentation
geometryChanged() |
Emitted when any of the properties of this Point changes.
Note: The corresponding handler is onGeometryChanged.
mChanged() |
Emitted when the m property of this Point changes.
Note: The corresponding handler is onMChanged.
xChanged() |
Emitted when the x property of this Point changes.
Note: The corresponding handler is onXChanged.
yChanged() |
Emitted when the y property of this Point changes.
Note: The corresponding handler is onYChanged.
zChanged() |
Emitted when the z property of this Point changes.
Note: The corresponding handler is onZChanged.
Method Documentation
void offsetBy(double offsetX, double offsetY) |
Move the builder's geometry in the x/y plane.
Returns this PointBuilder so you can easily chain method calls.
- offsetX - The offset along x-axis (negative value moves the point west).
- offsetY - The offset along y-axis (negative value moves the point south).
void setXY(double x, double y) |
Sets the x,y-coordinates of the point.
- x - The x-coordinate.
- y - The y-coordinate.
string toText() |
Returns a string representing this point.
The string has this format: Point(<x-coordinate>, <y-coordinate>, <z-coordinate>, <m-value>) WKID: <wkid-value>.
Note that z-coordinates and m-values are omitted if not present, along with their leading commas.
