Class ScalingRule

java.lang.Object

software.amazon.awssdk.services.emr.model.ScalingRule

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<ScalingRule.Builder,ScalingRule>

@Generated(value="software.amazon.awssdk:codegen")
public final class ScalingRule
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<ScalingRule.Builder,ScalingRule>

A scale-in or scale-out rule that defines scaling activity, including the CloudWatch metric alarm that triggers activity, how EC2 instances are added or removed, and the periodicity of adjustments. The automatic scaling policy for an instance group can comprise one or more automatic scaling rules.

Method Detail

name

public final String name()

The name used to identify an automatic scaling rule. Rule names must be unique within a scaling policy.

Returns:

The name used to identify an automatic scaling rule. Rule names must be unique within a scaling policy.

description

public final String description()

A friendly, more verbose description of the automatic scaling rule.

Returns:

A friendly, more verbose description of the automatic scaling rule.

action

public final ScalingAction action()

The conditions that trigger an automatic scaling activity.

Returns:

The conditions that trigger an automatic scaling activity.

trigger

public final ScalingTrigger trigger()

The CloudWatch alarm definition that determines when automatic scaling activity is triggered.

Returns:

The CloudWatch alarm definition that determines when automatic scaling activity is triggered.

toBuilder

public ScalingRule.Builder toBuilder()

Description copied from interface: ToCopyableBuilder

Take this object and create a builder that contains all of the current property values of this object.

Specified by:

toBuilder in interface ToCopyableBuilder<ScalingRule.Builder,ScalingRule>

Returns:

a builder for type T

builder

public static ScalingRule.Builder builder()

serializableBuilderClass

public static Class<? extends ScalingRule.Builder> serializableBuilderClass()

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

equalsBySdkFields

public final boolean equalsBySdkFields(Object obj)

Description copied from interface: SdkPojo

Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

Specified by:

equalsBySdkFields in interface SdkPojo

Parameters:

obj - the object to be compared with

Returns:

true if the other object equals to this object by sdk fields, false otherwise.

toString

public final String toString()

Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.

Overrides:

toString in class Object

getValueForField

public final <T> Optional<T> getValueForField(String fieldName,
                                              Class<T> clazz)

sdkFields

public final List<SdkField<?>> sdkFields()

Specified by:

sdkFields in interface SdkPojo

Returns:

List of SdkField in this POJO. May be empty list but should never be null.
