All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<HystrixCollapser.Scope>

Enclosing class:

HystrixCollapser<BatchReturnType,ResponseType,RequestArgumentType>

public static enum HystrixCollapser.Scope
extends java.lang.Enum<HystrixCollapser.Scope>

The scope of request collapsing.

• REQUEST: Requests within the scope of a HystrixRequestContext will be collapsed.

  Typically this means that requests within a single user-request (ie. HTTP request) are collapsed. No interaction with other user requests. 1 queue per user request.

• GLOBAL: Requests from any thread (ie. all HTTP requests) within the JVM will be collapsed. 1 queue for entire app.

public static HystrixCollapser.Scope[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (HystrixCollapser.Scope c : HystrixCollapser.Scope.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:
