These examples assume there are previously created Person objects containing attributes such as name , age , and gender. This package contains the ehcache lookup interface and implementation for the supported JTA transaction managers. Caches can be made searchable, on a per cache basis, either by configuration or programmatically. Before creating a query, the cache configuration must be prepared as described in Making a Cache Searchable. The DynamicAttributesExtractor provides flexibility by allowing the search configuration to be changed after the cache is initialized. This package contains only a ShutdownListener, useful for shutting down CacheManager in web apps. Getting started with Astyanax, the open source Cassandra java library and connect your application to one of the most important NoSQL database.

For example, if a query finds elements, there will be Result objects. The interface's attributeFor method returns the attribute value for the element and attribute name you specify.

The Search API allows you to execute arbitrarily complex queries against caches. However, calls to includeKeys and includeValues do take time, so consider carefully when constructing your queries.

A Query is built up using Expressions.

An extracted attribute must be one of the following types:. Get Started with Astyanax, the Cassandra java library by Netflix. If you do not want automatic indexing of keys and values, you can disable it using:.

Javasoc development of alternative indexes on values provides the ability for data to be looked up based on multiple criteria instead of just keys.

By default, a query can return an unlimited number of results.

If too many results are returned, it could cause an OutOfMemoryError The maxResults clause is used to limit the size of the results. The GroupBy feature provides the option to group results according to specified attributes. When you are done with the results, call the discard method to free up resources.

Given the code above, the newly put element would be indexed on values of name and age fields, but not gender.

For even greater readability, statically import so that, in this example, you would use KEY. On the first use of an attribute, the attribute type is detected, validated against supported types, and saved automatically.

ILike is always case insensitive. This package contains the SizeOf filtering interface and implementations for the pooling in Ehcache.

Queries return a Results object that contains a list of objects of class Result. For example, to find the sum of the age attribute: In more complex situations, you can create your own attribute extractor by implementing the AttributeExtractor interface.

The only exception is when the updating thread performs a search. Note that placing a javadox in front of the expression will cause a table scan. If an attribute cannot be found or is of the wrong type, an AttributeExtractorException is thrown on search execution.

From the starting object, a chain of method calls or field names follows. This package contains interfaces and classes for Hibernate related to Ehcache's nonstop feature.

Method calls and field names can be freely mixed in the chain:. The parts of an Element that are well-known attributes can be referenced by some predefined, well-known names.

This package contains the main classes and interfaces for the new fully coherent combination disk and memory store for unclustered Ehcache. This package contains only a ShutdownListener, useful for shutting down CacheManager in web apps.

The DynamicAttributesExtractor method returns a map of attribute names to index and their respective values. Add the Maven Dependecy to your project: To add a criterion with a different logical operator, explicitly nest ehcahce within a new logical operator Criteria object.
