Marshall Schor commented on UIMA-4687: -------------------------------------- For UIMA V3 JCas, we could add some static final constants for the type and feature names: {code} public final static String _TypeName = "pack.age.name.Sentence"; // new static final string constants added public final static String _FeatName_xxxx = "xxxx"; // for features // allows @TypeCapability( // use example inputTypes = { @Type(Sentence._TypeName ), @Type(value=Token.class, features={Token._FeatName_pos , Token._FeatName_lemma})}) {code} {code} @Type(Sentence._TYPE_NAME) {code} Would this satisfy the needs you envisioned here and in UIMA-2147? > UV3 improve JCas feature id use for index corruption checking and journaling > ---------------------------------------------------------------------------- > > Key: UIMA-4687 > URL: https://issues.apache.org/jira/browse/UIMA-4687 > Project: UIMA > Issue Type: Sub-task > Components: Core Java Framework > Reporter: Marshall Schor > Assignee: Marshall Schor > Priority: Minor > Fix For: 3.0.0SDKexp > > > When setting (changing) values for features, sometimes index corruption > checking needs to be done, and sometimes changes need to be journaled. Both > of these need to identify the feature involved. This operation should be > fast and memory-cache-friendly (e.g. not involve following a long chain of > dereferencings). > Add static final fields that represent features used by a particular JCas > class, which have names derived from the short-feature-name, and won't > collide with other names, and set these using the same JCasRegistry mechanism > to unique values within a class loader. This allows the same JCas cover > classes to be used with different type systems. > Change the corruption testing logic to use BitSets and have a version which > uses these indexes as well as one which uses the FeatureImpl featureCode. > Keep one extra table mapping these codes to FeatureImpls, per type system. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
