@Generated(value="com.amazonaws:aws-java-sdk-code-generator")
public class AutoScalingPolicy
extends Object
implements Serializable, Cloneable, StructuredPojo

An automatic scaling policy for a core instance group or task instance group in an Amazon EMR cluster. An automatic scaling policy defines how an instance group dynamically adds and terminates EC2 instances in response to the value of a CloudWatch metric. See PutAutoScalingPolicy.

public AutoScalingPolicy()

Method Detail

setConstraints

public void setConstraints(ScalingConstraints constraints)

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

Parameters:

constraints - The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

getConstraints

public ScalingConstraints getConstraints()

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

Returns:

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

withConstraints

public AutoScalingPolicy withConstraints(ScalingConstraints constraints)

The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

Parameters:

constraints - The upper and lower EC2 instance limits for an automatic scaling policy. Automatic scaling activity will not cause an instance group to grow above or below these limits.

Returns:

Returns a reference to this object so that method calls can be chained together.

getRules

public List<ScalingRule> getRules()

The scale-in and scale-out rules that comprise the automatic scaling policy.

Returns:

The scale-in and scale-out rules that comprise the automatic scaling policy.

setRules

public void setRules(Collection<ScalingRule> rules)

The scale-in and scale-out rules that comprise the automatic scaling policy.

Parameters:

rules - The scale-in and scale-out rules that comprise the automatic scaling policy.

withRules

public AutoScalingPolicy withRules(ScalingRule... rules)

The scale-in and scale-out rules that comprise the automatic scaling policy.

NOTE: This method appends the values to the existing list (if any). Use setRules(java.util.Collection) or withRules(java.util.Collection) if you want to override the existing values.

Parameters:

rules - The scale-in and scale-out rules that comprise the automatic scaling policy.

Returns:

Returns a reference to this object so that method calls can be chained together.

withRules

public AutoScalingPolicy withRules(Collection<ScalingRule> rules)

The scale-in and scale-out rules that comprise the automatic scaling policy.

Parameters:

rules - The scale-in and scale-out rules that comprise the automatic scaling policy.

Returns:

Returns a reference to this object so that method calls can be chained together.

toString

public String toString()

Returns a string representation of this object; useful for testing and debugging.

Overrides:

toString in class Object

Returns:

A string representation of this object.

equals

public boolean equals(Object obj)

Overrides:

marshall

public void marshall(ProtocolMarshaller protocolMarshaller)

Description copied from interface: StructuredPojo
