multi-key-lookup
A data structure that allows indexing by multiple fields for fast data access.
Basic Usage
Pass the data and an array of index fields to the constructor. Get the data with a field and value.
public class DataClass
{
public int A { get; set; }
public int B { get; set; }
public int C { get; set; }
}
public void Get()
{
var Data = new DataClass[] {new DataClass() { A = 1, B = 2, C = 3 },
new DataClass() { A = 1, B = 3, C = 2 }, new DataClass(){ A = 3, B = 2, C = 1}};
var Indexed = new MultiKeyLookup(Data, ("A", k => k.A), ("B", k => k.B));
IEnumerable<DataClass> A1 = Indexed.get('A', 1);
IEnumerable<DataClass> B2 = Indexed.get('B', 2);
//prints [{a: 1, b: 2, c: 3}, {a: 1, b: 3, c: 2}]
Console.WriteLine(A1);
//prints [{a: 1, b: 2, c: 3}, {a: 3, b: 2, c: 1}]
Console.WriteLine(B2);
}
API
new MultiKeyLookup(data, ...indexes); //data and indexes are optional
Count; //the number of data entries
Indexes; //the number of indexes
Values; //gets an iterable of values
AddIndex((field, fieldSelector)); //indexes the data by another index
RemoveIndex(field); //removes an index
Add(...data); //adds data
ContainsKey(field, key, fieldSelector); //does the data exist by field and key, fieldSelector needed for no index
TryGetValue(field, key, fieldSelector); //gets the data by field and key, fieldSelector needed for no index
GetValueOrDefault(field, key, fieldSelector); //get a single value or default by field and key, fieldSelector needed for no index
Get(field, key, fieldSelector); //gets the data by field and key, fieldSelector needed for no index
Remove(field, key, fieldSelector); //removes the data by field and key, fieldSelector needed for no index
