C# Class MyMediaLite.IO.RelationData

Class that offers static methods to read (binary) relation over entities into SparseBooleanMatrix objects

Public Methods

Method	Description
Read ( IDataReader reader, IEntityMapping mapping ) : SparseBooleanMatrix	Read binary relation data from an IDataReader, e.g. a database via DbDataReader
Read ( StreamReader reader, IEntityMapping mapping ) : SparseBooleanMatrix	Read binary relation data from file The expected (sparse) line format is: ENTITY_ID whitespace ENTITY_ID for the relations that hold.
Read ( string filename, IEntityMapping mapping ) : SparseBooleanMatrix	Read binary attribute data from file The expected (sparse) line format is: ENTITY_ID whitespace ENTITY_ID for the relations that hold.

Read binary relation data from an IDataReader, e.g. a database via DbDataReader

public static Read ( IDataReader reader, IEntityMapping mapping ) : SparseBooleanMatrix
reader	IDataReader	an IDataReader to be read from
mapping	IEntityMapping	the mapping object for the given entity type
return	MyMediaLite.DataType.SparseBooleanMatrix

Read binary relation data from file

The expected (sparse) line format is: ENTITY_ID whitespace ENTITY_ID for the relations that hold.

public static Read ( StreamReader reader, IEntityMapping mapping ) : SparseBooleanMatrix
reader	System.IO.StreamReader	a StreamReader to be read from
mapping	IEntityMapping	the mapping object for the given entity type
return	MyMediaLite.DataType.SparseBooleanMatrix

Read binary attribute data from file

The expected (sparse) line format is: ENTITY_ID whitespace ENTITY_ID for the relations that hold.

public static Read ( string filename, IEntityMapping mapping ) : SparseBooleanMatrix
filename	string	the name of the file to be read from
mapping	IEntityMapping	the mapping object for the given entity type
return	MyMediaLite.DataType.SparseBooleanMatrix
