Class Target

java.lang.Object

software.amazon.awssdk.services.ssm.model.Target

All Implemented Interfaces:

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

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

An array of search criteria that targets instances using a Key,Value combination that you specify.

Supported formats include the following.

• Key=InstanceIds,Values=instance-id-1,instance-id-2,instance-id-3

• Key=tag:my-tag-key,Values=my-tag-value-1,my-tag-value-2

• Key=tag-key,Values=my-tag-key-1,my-tag-key-2

• Run Command and Maintenance window targets only: Key=resource-groups:Name,Values=resource-group-name

• Maintenance window targets only: Key=resource-groups:ResourceTypeFilters,Values=resource-type-1,resource-type-2

• Automation targets only: Key=ResourceGroup;Values=resource-group-name

For example:

• Key=InstanceIds,Values=i-02573cafcfEXAMPLE,i-0471e04240EXAMPLE,i-07782c72faEXAMPLE

• Key=tag:CostCenter,Values=CostCenter1,CostCenter2,CostCenter3

• Key=tag-key,Values=Name,Instance-Type,CostCenter

• Run Command and Maintenance window targets only: Key=resource-groups:Name,Values=ProductionResourceGroup

  This example demonstrates how to target all resources in the resource group ProductionResourceGroup in your maintenance window.

• Maintenance window targets only: Key=resource-groups:ResourceTypeFilters,Values=AWS::EC2::INSTANCE,AWS::EC2::VPC

  This example demonstrates how to target only EC2 instances and VPCs in your maintenance window.

• Automation targets only: Key=ResourceGroup,Values=MyResourceGroup

• State Manager association targets only: Key=InstanceIds,Values=*

  This example demonstrates how to target all managed instances in the AWS Region where the association was created.

For more information about how to send commands that target instances using Key,Value parameters, see Targeting multiple instances in the AWS Systems Manager User Guide.

Method Detail

key

public String key()

User-defined criteria for sending commands that target instances that meet the criteria.

Returns:

User-defined criteria for sending commands that target instances that meet the criteria.

hasValues

public boolean hasValues()

Returns true if the Values property was specified by the sender (it may be empty), or false if the sender did not specify the value (it will be empty). For responses returned by the SDK, the sender is the AWS service.

values

public List<String> values()

User-defined criteria that maps to Key. For example, if you specified tag:ServerRole, you could specify value:WebServer to run a command on instances that include EC2 tags of ServerRole,WebServer.

Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

You can use hasValues() to see if a value was sent in this field.

Returns:

User-defined criteria that maps to Key. For example, if you specified tag:ServerRole, you could specify value:WebServer to run a command on instances that include EC2 tags of ServerRole,WebServer.

toBuilder

public Target.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<Target.Builder,Target>

Returns:

a builder for type T

builder

public static Target.Builder builder()

serializableBuilderClass

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

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

equalsBySdkFields

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

sdkFields

public 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.
