Class Entity

java.lang.Object
software.amazon.awssdk.services.cloudwatch.model.Entity
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<Entity.Builder,Entity>
@Generated("software.amazon.awssdk:codegen") public final class Entity extends Object implements SdkPojo, Serializable, ToCopyableBuilder<Entity.Builder,Entity>

An entity associated with metrics, to allow for finding related telemetry. An entity is typically a resource or service within your system. For example, metrics from an Amazon EC2 instance could be associated with that instance as the entity. Similarly, metrics from a service that you own could be associated with that service as the entity.

  • Method Details

    • hasKeyAttributes

      public final boolean hasKeyAttributes()
      For responses, this returns true if the service returned a value for the KeyAttributes property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • keyAttributes

      public final Map<String,String> keyAttributes()

      The attributes of the entity which identify the specific entity, as a list of key-value pairs. Entities with the same KeyAttributes are considered to be the same entity. For an entity to be valid, the KeyAttributes must exist and be formatted correctly.

      There are five allowed attributes (key names): Type, ResourceType, Identifier, Name, and Environment.

      For details about how to use the key attributes to specify an entity, see How to add related information to telemetry in the CloudWatch User Guide.

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

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasKeyAttributes() method.

      Returns:
      The attributes of the entity which identify the specific entity, as a list of key-value pairs. Entities with the same KeyAttributes are considered to be the same entity. For an entity to be valid, the KeyAttributes must exist and be formatted correctly.

      For responses, this returns true if the service returned a value for the Attributes property.

    • attributes

      public final Map<String,String> attributes()

      Additional attributes of the entity that are not used to specify the identity of the entity. A list of key-value pairs.

      For details about how to use the attributes, see How to add related information to telemetry in the CloudWatch User Guide.

    • toBuilder

      public Entity.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<Entity.Builder,Entity>
      Returns:
      a builder for type T

    • builder

      public static Entity.Builder builder()

    • serializableBuilderClass

      public static Class<? extends Entity.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.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
