    • SimpleColumnPattern

      public SimpleColumnPattern​(@NotNull @NotNull java.lang.String realColumnName, @NotNull @NotNull ColumnParser<T> parser, @NotNull @NotNull java.util.function.BiFunction<U,​T,​U> setter)
      Creates a new simple column pattern, i.e. a pattern which specifies a specific column name. This constructor may be used if SimpleColumnPattern is an immutable type.
      Parameters:
      realColumnName - The exact name of the column to match.
      parser - The parser to convert values from and to a SQL representation.
      setter - The function used to set a parsed value to a given object. The setter should only return a new object of type SimpleColumnPattern if the handed in one is immutable.

      public SimpleColumnPattern​(@NotNull @NotNull java.lang.String realColumnName, @NotNull @NotNull ColumnParser<T> parser, @NotNull @NotNull java.util.function.BiFunction<U,​T,​U> setter, @NotNull @NotNull java.util.Optional<java.util.Optional<T>> defaultValue, boolean isPrimaryKey, boolean allowNull)
      Creates a new simple column pattern, i.e. a pattern which specifies a specific column name. This constructor may be used if SimpleColumnPattern is an immutable type.
      Parameters:
      realColumnName - The exact name of the column to match.
      parser - The parser to convert values from and to a SQL representation.
      setter - The function used to set a parsed value to a given object. The setter should only return a new object of type SimpleColumnPattern if the handed in one is immutable.
      defaultValue - The default value of this column. Optional.empty() represents explicitely no default value. An Optional of an Optional.empty() represents null as default value. Otherwise the value of the inner Optional represents the default value.
