Class CASMgrSerializer

java.lang.Object
  extended by org.apache.uima.cas.impl.CASMgrSerializer
All Implemented Interfaces:
java.io.Serializable

public class CASMgrSerializer
extends java.lang.Object
implements java.io.Serializable

Container for serialized CAS typing information. Contains information about the type system, as well as the index repository. If more than one CAS that use the same type system and index repository need to be serialized, this information needs to be serialized only once.

Field Detail

SOURCE_JEDI

public static final int SOURCE_JEDI
See Also:
Constant Field Values

SOURCE_TAF

public static final int SOURCE_TAF
See Also:
Constant Field Values

typeOrder

public int[] typeOrder

indexNames

public java.lang.String[] indexNames
The index identifiers. Note that more than one identifier can refer to the same index.


nameToIndexMap

public int[] nameToIndexMap
A mapping from index names to index IDs. We have that indexNames.length == nameToIndexMap.length and for each i in nameToIndexMap, 0 <= i < indexTypes.length.


indexingStrategy

public int[] indexingStrategy
For each index, the indexing strategy of that index. Current options are SORTED_INDEX, SET_INDEX and BAG_INDEX. indexingStrategy.length == indexTypes.length.


comparatorIndex

public int[] comparatorIndex
For each index, where the corresponding comparator starts in the comparators field. comparatorIndex.length == indexTypes.length.


comparators

public int[] comparators
Encodings of the actual comparators. Each comparator occupies an odd number of cells: one for the type, then feature/comparison pairs. The feature is encoded with its type system code, and comparison operations are encoded with STANDARD_COMPARE and REVERSE_STANDARD_COMPARE.


typeNames

public java.lang.String[] typeNames
A list of type names (symbol table). Note: numbering of types starts at 1, and we index the names according to their internal code. That means that typeNames[0] == null.


featureNames

public java.lang.String[] featureNames
A list of feature names (symbol table). Note: numbering of features starts at 1, , and we index the names according to their internal code. That means that featureNames[0] == null.


typeInheritance

public int[] typeInheritance
Type inheritance information: for each type other than the top type, we provide the parent in the inheritance scheme. We use the internal type codes for indexing, which means that cells 0 (no type) and 1 (top type doesn't inherit from anything) are not used.


featDecls

public int[] featDecls
Feature declarations. For each feature code i (which is an integer >= 1), featDecls[(i-1)*3] is the domain type code, featDecls[(i-1)*3+1] is the range type code, and featDecls[(i-1)*3+2] is the multipleReferencesAllowed flag (0 or 1).


topTypeCode

public int topTypeCode
The internal code of the top type. Optional, used for sanity checks.


featureOffsets

public int[] featureOffsets
The offsets for features. Optional, used for sanity checks. Since feature numbering starts at 1, the length of the array is 1 + number of features.


stringSubtypes

public int[] stringSubtypes
A list of type codes for the string subtypes.


stringSubtypeValues

public java.lang.String[] stringSubtypeValues
The string values for the string subtypes. Start and end postions for the values for the individual types are in stringSubtypeValuePos.


stringSubtypeValuePos

public int[] stringSubtypeValuePos
The start positions of the string value subarrays of stringSubtypeValues. stringSubtypeValuePos.length == stringSubtypes.length. For each i < stringSubtypes.length, stringSubtypeValuePos[i] is the start of the string values for stringSubtypes[i].


source

public int source
Set this appropriately.
