This class is responsible for managing the input and output dependencies of distributed transactions. It contains logic to creating blocking data structures that are released once the appropriate VoltTables arrive for queries executed on remote partitions. @author pavlo
org.codehaus.groovy.tools.gse.DependencyTracker
org.wso2.carbon.mediation.dependency.mgt.DependencyTracker
Observes the Synapse configuration and constructs a model which represents the inter dependencies among various configuration items. The model is dynamically updated to reflect the changes made to the Synapse configuration at runtime. This class also enables querying the model to resolve dependencies among various configuration items.
