Class: Wheneverd::DSL::PeriodParser

Inherits:

Object

• Object
• Wheneverd::DSL::PeriodParser

Defined in:

lib/wheneverd/dsl/period_parser.rb

Overview

Converts DSL every(...) period values into trigger objects.

Supported period forms are described in the README.

Uses a strategy pattern to delegate parsing to specialized strategy classes:

• Wheneverd::DSL::PeriodStrategy::DurationStrategy for Duration values
• Wheneverd::DSL::PeriodStrategy::StringStrategy for interval strings and cron expressions
• Wheneverd::DSL::PeriodStrategy::SymbolStrategy for calendar symbols
• Wheneverd::DSL::PeriodStrategy::ArrayStrategy for arrays of calendar symbols

Instance Attribute Summary

• #path ⇒ Object readonly

  Returns the value of attribute path.

Instance Method Summary

• #initialize(path:) ⇒ PeriodParser constructor

  A new instance of PeriodParser.

• #trigger_for(period, at:) ⇒ Wheneverd::Trigger::Interval, Wheneverd::Trigger::Calendar

Constructor Details

#initialize(path:) ⇒ PeriodParser

Parameters:

• path (String) —

  schedule path for error reporting

#trigger_for(period, at:) ⇒ Wheneverd::Trigger::Interval, Wheneverd::Trigger::Calendar

Parameters:

• period (String, Symbol, Array<Symbol>, Wheneverd::Duration)

def trigger_for(period, at:)
  at_times = AtNormalizer.normalize(at, path: path)
  strategy = PeriodStrategy.for(period, path: path)
  strategy.parse(period, at_times: at_times)
rescue Wheneverd::InvalidIntervalError => e
  raise InvalidPeriodError.new(e.message, path: path)
