Examples with ESObject org.elasticsearch.annotation.ESObject used on opensource projects

Example 1 with ESObject

use of org.elasticsearch.annotation.ESObject in project alien4cloud by alien4cloud.

the class FlowExecutionContext method getConfiguration.

/**
 * Get a configuration object related to the deployment flow.
 *
 * This operation also updates the lastFlowParamUpdate that may be used by later processor to skip some processing when nothing has changed.
 *
 * The operation is also caching aware to avoid requesting multiple times the same object from elasticsearch.
 *
 * The configuration object is not annotated with {@link ESObject}, no request to elasticsearch will be made.
 *
 * @param cfgClass The class of the configuration object.
 * @param modifierName Name of the modifier that tries to access a deployment configuration object (related to the environment).
 * @param <T> The type of the configuration object.
 * @return An instance of the requested configuration object.
