Package com.netflix.discovery.util

Class EurekaEntityFunctions

java.lang.Object

com.netflix.discovery.util.EurekaEntityFunctions

public final class EurekaEntityFunctions
extends java.lang.Object

Collection of functions operating on Applications and Application data structures. The functions are organized into groups with common prefix name:

• select, take - queries over Eureka entity objects
• to - Eureka entity object transformers
• copy - copy Eureka entities, with aggregated InstanceInfo objects copied by reference
• deepCopy - copy Eureka entities, with aggregated InstanceInfo objects copied by value
• merge - merge two identical data structures
• count - statistical functions
• comparator - comparators for the domain objects
