Example 1 with QueryParameterSource

use of org.apache.geode.management.internal.web.domain.QueryParameterSource in project geode by apache.

the class AbstractHttpOperationInvoker method queryNames.

/**
   * This method searches the MBean server, based on the OperationsInvoker's JMX-based or remoting
   * capable MBean server connection, for MBeans matching a specific ObjectName or matching an
   * ObjectName pattern along with satisfying criteria from the Query expression.
   * 
   * @param objectName the ObjectName or pattern for which matching MBeans in the target MBean
   *        server will be returned.
   * @param queryExpression the JMX-based query expression used to filter matching MBeans.
   * @return a set of ObjectName's matching MBeans in the MBean server matching the ObjectName and
   *         Query expression criteria.
