Class Aggregate

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

Specifies a transform that groups rows by chosen fields and computes the aggregated value by specified function.

  • Method Details

    • name

      public final String name()

      The name of the transform node.

      Returns:
      The name of the transform node.

    • hasInputs

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

    • inputs

      public final List<String> inputs()

      Specifies the fields and rows to use as inputs for the aggregate transform.

      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 hasInputs() method.

      Returns:
      Specifies the fields and rows to use as inputs for the aggregate transform.

    • hasGroups

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

    • groups

      public final List<List<String>> groups()

      Specifies the fields to group by.

      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 hasGroups() method.

      Returns:
      Specifies the fields to group by.

    • hasAggs

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

    • aggs

      public final List<AggregateOperation> aggs()

      Specifies the aggregate functions to be performed on specified fields.

      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 hasAggs() method.

      Returns:
      Specifies the aggregate functions to be performed on specified fields.

    • toBuilder

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

    • builder

      public static Aggregate.Builder builder()

    • serializableBuilderClass

      public static Class<? extends Aggregate.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.
