#ctor
Default Constructor.
#ctor(
Int32, Double)Constructor.
Parameters
| Name | Type | Description |
|---|---|---|
index | Int32 | The index of the value. |
value | Double | The value to store. |
ToString
String representation of this Node as {index}:{value}.
Returns
{index}:{value}
Equals(
Object)Compares this node with another object.
Parameters
| Name | Type | Description |
|---|---|---|
obj | Object | The object that will be compared with this node. |
Returns
True when the obj is a Node object which has the same Node.index and the same truncated Node.value, otherwise False.
GetHashCode
Gets the hash code of this node, which is combined by the hash code of both the Node.index and the Node.value.
Returns
An Int32 hash code value.
CompareTo(Node)
Compares this node with another.
Parameters
| Name | Type | Description |
|---|---|---|
other | Node | The node to compare to |
Returns
A positive number if this node is greater, a negative number if it is less than, or 0 if equal
Copy(
IEnumerable(Of Node))Create a copy of a Node data collection.
Parameters
| Name | Type | Description |
|---|---|---|
dataset | IEnumerable(Of Node) | The source node collection. |
Returns
A lazy evaluated sequence of the new Node objects which have the same index and value as the source collection.
index
Index of this Node.
value
Value at Index.
