Parameters

Descriptors are simple classes that are used for storing symbology or other basic characteristics. They are presumed to be made up of value types and other descriptors, and are expected to be serializable. This being said, some basic capabilities are supported for randomizing, copying and comparing the properties of descriptors.

CopyBase

Creates a new instance of CopyBase

Creates a duplicate of this descriptor using MemberwiseClone

A clone of this object as a duplicate

PropertyInfo returns overridden members as separate entries. We would rather work with each members only one time.

All the properties, including duplicates created by overridden members An Array of PropertyInfo members

This occurs during the Copy method and is overridable by sub-classes

The duplicate descriptor

IDescriptor

Matching is defined as being a different object, but having properties that would make it indistinguishable from the comparision property. This is an alternative to overriding the equals behavior in cases where you might ALSO need to see if the object reference is the same.

Tests this object against the comparison object. If any of the value type members are different, or if any of the properties are IMatchable and do not match, then this returns false.

The other IMatcheable object of the same type The list of property names that do not match Boolean, true if the properties are comparably equal.

IRandomizable

This method will set the values for this class with random values that are within acceptable parameters for this class.

An existing random number generator so that the random seed can be controlled

This copies the public descriptor properties from the specified object to this object.

An object that has properties that match the public properties on this object.

Creates a new instance of MatchableObject

For each of the publicly accessible properties found on this object, this attempts to copy a public property from the source object of the same name, if it can find it. For each matching property name/type, it will attempt to copy the value.

The

Compares the properties of this object with the specified IMatchable other. This does not test every property of other, but does test every property of this item. As long as the other item has corresponding properties for every property on this item, the items are said to match. The IMatchable interface allows custom definitions of matching. For collections to match, all of their sub-members must match.

The default behavior is to cycle through all the properties of this object, and call Randomize on any that implement the IRandomizable interface.

The Random seed generator for controling how the random content is created

This occurs while copying properties from the specified source, and is the default handling for subclasses

This gives sub-classes the chance to directly override, control or otherwise tamper with the matching process. This is also where normal matching is performed, so to replace it, simply don't call the base.OnMatch method. To tweak the results, the base method should be performed first, and the results can then be modified.

This allows overrideable behavior that can replace or extend the basic behavior, which is to call Randomize on any public properties that are listed as randomizeable. This does nothing to normal properties or non public members and needs to be overriden to provide the special case functionality for sub-classes.

The random number generator to be used during randomization

The radius of the sphere

A spheroid is a pole flattened (oblate) sphere, with the radii of two axes being equal and longer than the third. This is the radial measure of the smaller polar axis in meters. One option is to specify this directly, but it can also be calculated using the major axis and the flattening factor.

Normally, cloning an object starts with MemberwiseClone, which creates a shallow copy of the object. For any members that derive from the Descriptor, however, any public properties or fields that implement ICloneable are copied (deep copy behavior). This is not always desirable, even if the member CAN be copied. This attribute causes the deep copy behavior to skip over properties marked with this attribute.
