All Implemented Interfaces:
Iterable<Type>, TypeSystemMgr, LowLevelTypeSystem, TypeSystem
public class TypeSystemImpl extends Object implements TypeSystem, TypeSystemMgr, LowLevelTypeSystem
Type system implementation. This class has static final (constant) values for built-in type codes, feature codes, feature offsets, and feature isInt. - these are used -- for various type-specific internal use -- static final constants in the built-in JCas class definitions - these are set by hand as final constants Threading: An instance of this object needs to be thread safe after creation, because multiple threads are reading info from it. - During creation, only one thread is creating. Association with Class Loaders, after type system is committed Because JCas classes are generated from the merged type system, and then loaded under some class loader, several use cases need to be accommodated. Multiple type systems committed in sequence within one UIMA application. - Under one class loader -- therefore, they share one JCas loaded classes definition - OK provided type system is compatible with JCas loaded definitions At commit time, a type system is compared with existing ones; if it is equal, then the typeImpl and featureImpls and all other instance vars are replaced with existing ones. -- this removes issues in type system mapping needed between "equal" type systems to get feature validation to work. -- implemented via custom hashcode and equals.

  • Field Details

    • DISABLE_TYPESYSTEM_CONSOLIDATION

      public static final String DISABLE_TYPESYSTEM_CONSOLIDATION
      Define this JVM property to disable equal type system consolidation. When a type system is committed, it normally is compared with other committed type systems that are still available (i.e. not garbage collected) to see if an existing type system is equal to the new one. - if so, then the existing one is reused. This may cause problems for applications which have obtained references to types and features of a type system before it is committed; the committed version may have different (but "equal") types and features.

    • ENABLE_STRICT_TYPE_SOURCE_CHECK

      public static final String ENABLE_STRICT_TYPE_SOURCE_CHECK
      Define this JVM property to enable strictly checking the source of a type with respect to its type system. Normally (i.e. when typesystem consolidation is enabled), types that are semantically equivalent should come from the same type system instances. There could be bugs (in client or framework code) or legacy code which simply ignores this requirement and still works. Therefore, this property allow to restore the old non-strict-checking behavior.

WARNING: This API will use the UIMA Framework's class loader to find a load JCas classes.

    • ll_isRefType

      public boolean ll_isRefType(int typeCode)
      Description copied from interface: LowLevelTypeSystem
      Checks if the type code is that of a reference type (anything that's not a basic type, currently Integer, String, Float, Boolean, Byte, Short, Long, Double, and subtypes of String - specifying allowed-values).
      Specified by:
      ll_isRefType in interface LowLevelTypeSystem
      Parameters:
      typeCode - The type code to check.
      Returns:
      true iff typeCode is the type code of a reference type.

    • ll_getTypeClass

      public final int ll_getTypeClass(int typeCode)
      Description copied from interface: LowLevelTypeSystem
      Determine the type class of a type. This is useful for generic CAS exploiters to determine what kind of data they're looking at. The type classes currently defined are:
      • TYPE_CLASS_INVALID -- Not a valid type code.
      • TYPE_CLASS_INT -- Integer type.
      • TYPE_CLASS_FLOAT -- Float type.
      • TYPE_CLASS_STRING -- String type.
      • TYPE_CLASS_INTARRAY -- Integer array.
      • TYPE_CLASS_FLOATARRAY -- Float array.
      • TYPE_CLASS_STRINGARRAY -- String array.
      • TYPE_CLASS_FSARRAY -- FS array.
      • TYPE_CLASS_FS -- FS type, i.e., all other types, including all user-defined types.
      This method is on the CAS, not the type system, since the specific properties of types are specific to the CAS. The type system does not know, for example, that the CAS treats arrays specially.
      Specified by:
      ll_getTypeClass in interface LowLevelTypeSystem
      Parameters:
      typeCode - The type code.
      Returns:
      A type class for the type code. TYPE_CLASS_INVALID if the type code argument does not represent a valid type code.

      public static int getAdjustedFeatureOffset(String featName)
      ******** OBSOLETE - only left in for supporting some jcas style in alpha level ************* This code is run when a JCas class is loaded and resolved, for the first time, as part of type system commit, or as part of statically loading the FSClassRegister class (where this is done for all the built-ins, once). It looks up the offset value in the type system (via a thread-local) hidden parameter: threadLocal value: referencing this type

      Returns:
      the offset in the int or ref data arrays for the named feature

    • createCallSite

      public static final MutableCallSite createCallSite(Class<? extends TOP> clazz, String featName)
      Creates and returns a new MutableCallSite, // * recording it in list of all callsites for this type, in a map by typename // * // * Done this way because // * - can't be a classloader-wide list of call sites - some might not be associated with this type system // * - can't be a typesystem-wide list of call sites - the JCas class might be used by multiple type systems // * and the first one to load it would set this value. // * - has to be pairs of feature name, call-site, in order to get the value to set, later // * -- doesn't need to be a hashmap, can be an arraylist of entry // * Type being loaded may not be known at this point.
      Parameters:
      clazz - the JCas class
      featName - the short name of the feature
      Returns:
      the created callsite

    • createCallSiteForBuiltIn

      public static final MutableCallSite createCallSiteForBuiltIn(Class<? extends TOP> clazz, String featName)
      INTERNAL API - DO NOT USE, MAY CHANGE WITHOUT NOTICE!

      Creates and returns a new MutableCallSite for a built-in type. This handles the special case where the staticTsi is initialized as a result of a builtin type JCas cover class being loaded in which case the callsite in the cover class is set after the staticTsi already has been committed and therefore won't automatically get its callsites updated during the commit. So we need to create a proper callsite already pointing to the correct feature offset here.

      Parameters:
      clazz - the JCas class
      featName - the short name of the feature
      Returns:
      the created callsite
