software.amazon.awssdk.services.ecs.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>

The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value. You define them.

The following basic restrictions apply to tags:

  • Maximum number of tags per resource - 50

  • For each resource, each tag key must be unique, and each tag key can have only one value.

  • Maximum key length - 128 Unicode characters in UTF-8

  • Maximum value length - 256 Unicode characters in UTF-8

  • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

  • Tag keys and values are case-sensitive.

  • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

    • key

      public final String key()

      One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

      Returns:
      One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

    • value

      public final String value()

      The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

      Returns:
      The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

    • 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.
