Class CasSeqAddrMaps
java.lang.Object
org.apache.uima.cas.impl.CasSeqAddrMaps
Manage the conversion of Items (FSrefs) 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.

addItemAddr
public void addItemAddr(int srcAddr, int tgtAddr, boolean inTarget) Add a new FS address - done during prescan of source Must call in heap scan order- Parameters:
srcAddr
- -tgtAddr
- -inTarget
- true if this type is in the target
-
addSrcAddrForTgt

srcAddr
- -inSrc
- -
-
getSrcAddrFromTgtSeq
public int getSrcAddrFromTgtSeq(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
