Example 21 with CacheException

use of javax.cache.CacheException in project ignite by apache.

the class CacheConfiguration method setIndexedTypes.

/**
     * Array of key and value type pairs to be indexed (thus array length must be always even).
     * It means each even (0,2,4...) class in the array will be considered as key type for cache entry,
     * each odd (1,3,5...) class will be considered as value type for cache entry.
     * <p>
     * The same key class can occur multiple times for different value classes, but each value class must be unique
     * because SQL table will be named as value class simple name.
     * <p>
     * To expose fields of these types onto SQL level and to index them you have to use annotations
     * from package {@link org.apache.ignite.cache.query.annotations}.
     *
     * @param indexedTypes Key and value type pairs.
     * @return {@code this} for chaining.
