ILcdDataObjectSets the value of the given property for this data object. The implementation is allowed to throw an exception if the given value can't be set.
The given property must be declared in thedata object's type or in one of its super types. In
other words, getDataType().getProperties().contains( aProperty ) should always be true.
Otherwise, the implementation should throw an IllegalArgumentException.setValue in interface ILcdDataObjectsetValue in class TLcdDataObjectaProperty - the property for which the value is to be setaValue - the value to setTLcdDataType.getProperty(String)public void invalidateObject()

ILcdCompositeCurve
The returned list is not guaranteed to be editable. See ILcdEditableCompositeCurve
for an editable variant of this interface.
Note that this adding curves to the result of calling this method may throw a
ClassCastException or IllegalArgumentException
in case the class of the curve(s) to add is not
compatible with the implementation of the composite curve. Implementations should
specify in their documentation all restrictions that apply in this context.

ILcdCurve
A set of predefined constants are defined in this interface,
which are used by the default ILcdCurve implementations
provided by LuciadLightspeed.
Custom implementations can define their own constants, and use them to interpret the interpolation of the curve.

ILcdCurveThis information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.

is bounded.
If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points)
the return value is unspecified.
It is highly recommended to return an undefined bounds.
You can create undefined bounds using the default constructors
of TLcdLonLatBounds
or TLcdXYBounds.
