  • Method Details

    • catalogId

      public final String catalogId()

      The ID of the Data Catalog where the partition in question resides. If none is provided, the Amazon Web Services account ID is used by default.

      Returns:
      The ID of the Data Catalog where the partition in question resides. If none is provided, the Amazon Web Services account ID is used by default.

    • databaseName

      public final String databaseName()

      The database containing the table.

      Returns:
      The database containing the table.

    • queryAsOfTime

      public final Instant queryAsOfTime()

      The time as of when to read the table contents. If not set, the most recent transaction commit time will be used. Cannot be specified along with TransactionId.

      Returns:
      The time as of when to read the table contents. If not set, the most recent transaction commit time will be used. Cannot be specified along with TransactionId.

    • hasQueryParameters

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

    • queryParameters

      public final Map<String,String> queryParameters()

      A map consisting of key-value pairs.

      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 hasQueryParameters() method.

      Returns:
      A map consisting of key-value pairs.

    • transactionId

      public final String transactionId()

      The transaction ID at which to read the table contents. If this transaction is not committed, the read will be treated as part of that transaction and will see its writes. If this transaction has aborted, an error will be returned. If not set, defaults to the most recent committed transaction. Cannot be specified along with QueryAsOfTime.

      Returns:
      The transaction ID at which to read the table contents. If this transaction is not committed, the read will be treated as part of that transaction and will see its writes. If this transaction has aborted, an error will be returned. If not set, defaults to the most recent committed transaction. Cannot be specified along with QueryAsOfTime.

    • toBuilder

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

    • builder

      public static QueryPlanningContext.Builder builder()

    • serializableBuilderClass

      public static Class<? extends QueryPlanningContext.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.
