  • Method Details

    • name

      public final String name()

      The name of the table.

      Returns:
      The name of the table.

    • createTime

      public final Instant createTime()

      The time that the table was created.

      Returns:
      The time that the table was created.

    • lastAccessTime

      public final Instant lastAccessTime()

      The last time the table was accessed.

      Returns:
      The last time the table was accessed.

    • tableType

      public final String tableType()

      The type of table. In Athena, only EXTERNAL_TABLE is supported.

      Returns:
      The type of table. In Athena, only EXTERNAL_TABLE is supported.

    • hasColumns

      public final boolean hasColumns()
      For responses, this returns true if the service returned a value for the Columns 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.

    • columns

      public final List<Column> columns()

      A list of the columns in the table.

      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 hasColumns() method.

      Returns:
      A list of the columns in the table.

    • hasPartitionKeys

      public final boolean hasPartitionKeys()
      For responses, this returns true if the service returned a value for the PartitionKeys 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.

    • partitionKeys

      public final List<Column> partitionKeys()

      A list of the partition keys in the table.

      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 hasPartitionKeys() method.

      Returns:
      A list of the partition keys in the table.

    • hasParameters

      public final boolean hasParameters()
      For responses, this returns true if the service returned a value for the Parameters 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.

    • parameters

      public final Map<String,String> parameters()

      A set of custom key/value pairs for table properties.

      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 hasParameters() method.

      Returns:
      A set of custom key/value pairs for table properties.

    • toBuilder

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

    • builder

      public static TableMetadata.Builder builder()

    • serializableBuilderClass

      public static Class<? extends TableMetadata.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.
