man PPI::Statement::Scheduled () - A scheduled code block

NAME

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

INHERITANCE

  PPI::Statement::Scheduled
  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 four types of scheduled block: 

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


  CHECK {
        # Executes after compile-phase 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.

METHODS

type

The CWtype method returns the type of scheduled block, which should always be one of 'BEGIN', 'CHECK', 'INIT' or 'END'.

block

With its name and implementation shared with PPI::Statement::Sub, the CWblock method finds and returns the actual Structure object of the block for this scheduled block.

Returns false if it cannot find a block (although why this might happen I'm not sure).

TO DO

- Write unit tests for this package
