Class Tag

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

Describes a tag. A tag is a key-value pair. You can add up to 50 tags to a single DynamoDB table.

Amazon Web Services-assigned tag names and values are automatically assigned the aws: prefix, which the user cannot assign. Amazon Web Services-assigned tag names do not count towards the tag limit of 50. User-assigned tag names have the prefix user: in the Cost Allocation Report. You cannot backdate the application of a tag.

For an overview on tagging DynamoDB resources, see Tagging for DynamoDB in the Amazon DynamoDB Developer Guide.

  • Method Details

    • key

      public final String key()

      The key of the tag. Tag keys are case sensitive. Each DynamoDB table can only have up to one tag with the same key. If you try to add an existing tag (same key), the existing tag value will be updated to the new value.

      Returns:
      The key of the tag. Tag keys are case sensitive. Each DynamoDB table can only have up to one tag with the same key. If you try to add an existing tag (same key), the existing tag value will be updated to the new value.

    • value

      public final String value()

      The value of the tag. Tag values are case-sensitive and can be null.

      Returns:
      The value of the tag. Tag values are case-sensitive and can be null.

    • toBuilder

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

    • builder

      public static Tag.Builder builder()

    • serializableBuilderClass

      public static Class<? extends Tag.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.
