      A column label.

      Returns:
      A column label.

    • type

      public final String type()

      The data type of the column.

      Returns:
      The data type of the column.

    • precision

      public final Integer precision()

      For DECIMAL data types, specifies the total number of digits, up to 38. For performance reasons, we recommend up to 18 digits.

      Returns:
      For DECIMAL data types, specifies the total number of digits, up to 38. For performance reasons, we recommend up to 18 digits.

    • scale

      public final Integer scale()

      For DECIMAL data types, specifies the total number of digits in the fractional part of the value. Defaults to 0.

      Returns:

    • nullable

      public final ColumnNullable nullable()

      Indicates the column's nullable status.

      If the service returns an enum value that is not available in the current SDK version, nullable will return ColumnNullable.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from nullableAsString().

      Returns:
      Indicates the column's nullable status.
      See Also:

    • nullableAsString

      public final String nullableAsString()

      Indicates the column's nullable status.

    • caseSensitive

      public final Boolean caseSensitive()

      Indicates whether values in the column are case-sensitive.

      Returns:
      Indicates whether values in the column are case-sensitive.

    • toBuilder

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

    • builder

      public static ColumnInfo.Builder builder()

    • serializableBuilderClass

      public static Class<? extends ColumnInfo.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.
