NAME

PPI::Statement::Scheduled - A scheduled code block

CONTENTS

INHERITANCE



  PPI::Statement::Scheduled
  isa PPI::Statement::Sub
      isa PPI::Statement
          isa PPI::Node
              isa PPI::Element



DESCRIPTION

A scheduled code block is one that is intended to be run at a specific time during the loading process.

There are five types of scheduled block:



  BEGIN {
        # Executes as soon as this block is fully defined
        ...
  }

  CHECK {
        # Executes after overall compile-phase in reverse order
        ...
  }

  UNITCHECK {
        # Executes after compile-phase of individual module in reverse order
        ...
  }

  INIT {
        # Executes just before run-time
        ...
  }

  END {
        # Executes as late as possible in reverse order
        ...
  }



Technically these scheduled blocks are actually subroutines, and in fact may have ’sub’ in front of them.
