Interface UpdateOperation<K extends Comparable<K>>

Type Parameters:
K - consumed record key type
All Known Subinterfaces:
UpdateOperation.CellUpdateOperation<K,T>
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface UpdateOperation<K extends Comparable<K>>
A transform that updates a record.

  • Method Details

    • apply

      Iterable<Cell<?>> apply(Record<K> t)
      Applies this transform to the given record.
      Parameters:
      t - the incoming record
      Returns:
      the resultant cells

    • install

      static <K extends Comparable<K>> UpdateOperation<K> install(Cell<?>... cells)
      Creates a transform that outputs the specified set of cells. When used to update a record, this will result in any other cells being deleted from the record.
      Type Parameters:
      K - consumed record key type
      Parameters:
      cells - cells to install
      Returns:
      a cell installing transform

    • install

      static <K extends Comparable<K>> UpdateOperation<K> install(Iterable<Cell<?>> cells)
      Creates a transform that outputs the specified set of cells. When used to update a record, this will result in any other cells being deleted from the record.
      Type Parameters:
      K - consumed record key type
      Parameters:
      cells - a non-null Iterable supplying cells to install
      Returns:
      a cell installing transform
      Throws:
      NullPointerException - if cells is null

    • custom

      static <K extends Comparable<K>> UpdateOperation<K> custom(Function<Record<K>,Iterable<Cell<?>>> custom)
      Creates a custom transform that applies the given user supplied function.
      Type Parameters:
      K - consumed record key type
      Parameters:
      custom - user transform to execute
      Returns:
      a custom transform

    • allOf

      static <K extends Comparable<K>> UpdateOperation<K> allOf(UpdateOperation.CellUpdateOperation<?,?>... transforms)
      Creates a compound transform composed of the given individual cell mutations.
      Type Parameters:
      K - consumed record key type
      Parameters:
      transforms - list of transforms to perform
      Returns:
      a compounded transform

    • allOf

      static <K extends Comparable<K>> UpdateOperation<K> allOf(List<? extends UpdateOperation.CellUpdateOperation<?,?>> transforms)
      Creates a compound transform composed of the given individual cell mutations.
      Type Parameters:
      K - consumed record key type
      Parameters:
      transforms - list of transforms to perform
      Returns:
      a compounded transform
