Methods
| Name | Description | |
|---|---|---|
| Equals(Object) |
Specifies whether this object contains the same members as the specified Object.
(Overrides ValueTypeEquals(Object).) |
| Equals(KeyPoint) |
Specifies whether this object contains the same members as the specified Object.
|
| GetHashCode |
Returns a hash code for this object.

| ToString |
Converts this object to a human readable string.
(Overrides ValueTypeToString.) |
Operators
| Name | Description | |
|---|---|---|
