C# Class DataMigration.AbstractBaseExistence

A base class for existence objects that can use a C# HashSet for their implementation. Child classes usually just implement Init() to populate the HashSet, or they can leave it empty; plan-specific existence objects can use this mechanism to implement a first-writer-wins de-duping strategry on feed data items.

Public Methods

Method	Description
Add ( string value ) : void	Adds a single value to the IExistence collection.
Exists ( string value ) : bool	Determines if an external value exists in the collection.
Init ( ) : void	This is essentially a two-phase ctor. The sequence of construction is, instantiate the object, then set its properties, then call Init() so it can migrate the property values to their implementation-specific roles. In this abstract class, this method is not implemented (by design). It's up to concrete child classes to implement this, depending on their context.

Method Details

Add() public method

Adds a single value to the IExistence collection.

public Add ( string value ) : void
value	string	Value.
return	void

Exists() public method

Determines if an external value exists in the collection.

public Exists ( string value ) : bool
value	string	Value to check existence for.
return	bool

Init() public method

This is essentially a two-phase ctor. The sequence of construction is, instantiate the object, then set its properties, then call Init() so it can migrate the property values to their implementation-specific roles. In this abstract class, this method is not implemented (by design). It's up to concrete child classes to implement this, depending on their context.

public Init ( ) : void
return	void
