Class Index

  • public class Index
    extends java.lang.Object
    Information about configured settings of a field or field collection (an actual index or not) in a search definition. There are two types of settings:
    • Typed commands are checked using a particular is/get method
    • Untyped commands are checked using hasCommand and commandIterator
    addCommand sets both types.
