org.apache.uima.cas.impl.CasSeqAddrMaps

public class CasSeqAddrMaps
extends Object

Used by Binary serialization form 4 and 6 Manage the conversion of FSs to relative sequential index number, and back Manage the difference in two type systems both size of the FSs and handling excluded types During serialization, these maps are constructed before serialization. During deserialization, these maps are constructed while things are being deserialized, and then used in a "fixup" call at the end. This allows for forward references. For delta deserialization, the base part of these maps (for below-the-line) is constructed by scanning up to the mark.

Method Details

addItemId

public void addItemId(TOP srcFs,
 int tgtId,
 boolean inTarget)

Add a new FS id - done during prescan of source during serialization Must call in heap scan order

Parameters:

srcFs - -

tgtId - -

inTarget - true if this type is in the target

addSrcFsForTgt

public void addSrcFsForTgt(TOP srcFs,
 boolean inSrc)

Called during deserialize to incrementally add

Parameters:

srcFs - -

inSrc - -

getSrcFsFromTgtSeq

public TOP getSrcFsFromTgtSeq(int seq)

Parameters:

seq - -

Returns:

0 means target seq doesn't exist in source CAS

getTgtSeqFromSrcAddr

public int getTgtSeqFromSrcAddr(int itemAddr)

Parameters:

itemAddr - -

Returns:

-1 if src addr not in target seq

getNumberSrcFss

public int getNumberSrcFss()
