Syntax

public sealed class DirectoryTaxonomyWriter.DiskOrdinalMap : DirectoryTaxonomyWriter.IOrdinalMap

Constructors

DiskOrdinalMap(string)

Sole constructor.

Declaration

public DiskOrdinalMap(string tmpfile)

Parameters

Type	Name	Description
string	tmpfile

Methods

AddDone()

Call AddDone() to say that all AddMapping(int, int) have been done. In some implementations this might free some resources.

Declaration

public void AddDone()

AddMapping(int, int)

Record a mapping.

Declaration

public void AddMapping(int origOrdinal, int newOrdinal)

Parameters

Type	Name	Description
int	origOrdinal
int	newOrdinal

GetMap()

Return the map from the taxonomy's original (consecutive) ordinals to the new taxonomy's ordinals. If the map has to be read from disk and ordered appropriately, it is done when getMap() is called. getMap() should only be called once, and only when the map is actually needed. Calling it will also free all resources that the map might be holding (such as temporary disk space), other than the returned int[].

Declaration

public int[] GetMap()

Returns

Type	Description
int[]

SetSize(int)

Set the size of the map. This MUST be called before AddMapping(int, int). It is assumed (but not verified) that AddMapping(int, int) will then be called exactly 'size' times, with different origOrdinals between 0 and size - 1.

Declaration

public void SetSize(int taxonomySize)

Parameters

Type	Name	Description
int	taxonomySize
