@Generated("software.amazon.awssdk:codegen") public final class KeyspacesRow extends Object implements SdkPojo, Serializable, ToCopyableBuilder<KeyspacesRow.Builder,KeyspacesRow>

Represents a row in an Amazon Keyspaces table, containing regular column values, static column values, and row-level metadata.

  • Method Details

    • hasValueCells

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

    • valueCells

      public final Map<String,KeyspacesCell> valueCells()

      A map of regular (non-static) column cells in the row, where keys are column names and values are the corresponding cells.

      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 hasValueCells() method.

      Returns:
      A map of regular (non-static) column cells in the row, where keys are column names and values are the corresponding cells.

    • hasStaticCells

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

    • staticCells

      public final Map<String,KeyspacesCell> staticCells()

      A map of static column cells shared by all rows with the same partition key, where keys are column names and values are the corresponding cells.

      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 hasStaticCells() method.

      Returns:
      A map of static column cells shared by all rows with the same partition key, where keys are column names and values are the corresponding cells.

    • rowMetadata

      public final KeyspacesMetadata rowMetadata()

      Metadata that applies to the entire row, such as timestamps and TTL information.

      Returns:
      Metadata that applies to the entire row, such as timestamps and TTL information.

    • toBuilder

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

    • builder

      public static KeyspacesRow.Builder builder()

    • serializableBuilderClass

      public static Class<? extends KeyspacesRow.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.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
