This class defines new Groovy methods which appear on normal JDK Date/Time API (java.time) classes inside the Groovy environment. These extensions require JDK 8 or above.

  • Method Details

    • upto

      public static void upto(Temporal from, Temporal to, Closure closure)
      Iterates from this to the to Temporal, inclusive, incrementing by one unit each iteration, calling the closure once per iteration. The closure may accept a single Temporal argument.

      The particular unit incremented by depends on the specific subtype of Temporal. Most subtypes use a unit of ChronoUnit.SECONDS except for

      Parameters:
      from - the starting Temporal
      to - the ending Temporal
      closure - the zero or one-argument closure to call
      Throws:
      GroovyRuntimeException - if this value is later than to
      GroovyRuntimeException - if to is a different type than this
      Since:
      2.5.0

    • upto

      public static void upto(Temporal from, Temporal to, TemporalUnit unit, Closure closure)
      Iterates from this to the to Temporal, inclusive, incrementing by one unit each iteration, calling the closure once per iteration. The closure may accept a single Temporal argument.

      If the unit is too large to iterate to the second Temporal exactly, such as iterating from two LocalDateTimes that are seconds apart using ChronoUnit.DAYS as the unit, the iteration will cease as soon as the current value of the iteration is later than the second Temporal argument. The closure will not be called with any value later than the to value.

      Parameters:
      from - the starting Temporal
      to - the ending Temporal
      unit - the TemporalUnit to increment by
      closure - the zero or one-argument closure to call
      Throws:
      GroovyRuntimeException - if this value is later than to
      GroovyRuntimeException - if to is a different type than this
      Since:
      2.5.0

    • downto

      public static void downto(Temporal from, Temporal to, Closure closure)
      Iterates from this to the to Temporal, inclusive, decrementing by one unit each iteration, calling the closure once per iteration. The closure may accept a single Temporal argument.

      The particular unit decremented by depends on the specific subtype of Temporal. Most subtypes use a unit of ChronoUnit.SECONDS except for

      Parameters:
      from - the starting Temporal
      to - the ending Temporal
      closure - the zero or one-argument closure to call
      Throws:
      GroovyRuntimeException - if this value is earlier than to
      GroovyRuntimeException - if to is a different type than this
      Since:
      2.5.0

    • downto

      public static void downto(Temporal from, Temporal to, TemporalUnit unit, Closure closure)
      Iterates from this to the to Temporal, inclusive, decrementing by one unit each iteration, calling the closure once per iteration. The closure may accept a single Temporal argument.

      If the unit is too large to iterate to the second Temporal exactly, such as iterating from two LocalDateTimes that are seconds apart using ChronoUnit.DAYS as the unit, the iteration will cease as soon as the current value of the iteration is earlier than the second Temporal argument. The closure will not be called with any value earlier than the to value.

      Parameters:
      from - the starting Temporal
      to - the ending Temporal
      unit - the TemporalUnit to increment by
      closure - the zero or one-argument closure to call
      Throws:
      GroovyRuntimeException - if this value is earlier than to
      GroovyRuntimeException - if to is a different type than this
      Since:
      2.5.0
