Detailed Description

This module contains the code for the low-level MvrType object.

Function/Subroutine Documentation

advance()

subroutine mvrmodule::advance ( class(mvrtype)  this )

private

Advance mover object. Does nothing now.

Definition at line 211 of file Mover.f90.

echo()

subroutine mvrmodule::echo	(	class(mvrtype)	this,
		integer(i4b), intent(in)	iout
	)

Write mover values to output file.

Parameters

	this	MvrType
[in]	iout	unit number for output file

prepare()

subroutine mvrmodule::prepare	(	class(mvrtype)	this,
		integer(i4b), intent(in)	inunit,
		character(len=lenmempath), dimension(:), pointer, contiguous	pckMemPaths,
		type(packagemovertype), dimension(:), pointer, contiguous	pakmovers
	)

Set values and pointers for mover object. pckMemPaths is an array of strings which are the memory paths for those packages. They are composed of model names and package names. The mover entries must be in pckMemPaths, or this routine will terminate with an error.

Parameters

	this	MvrType object
[in]	inunit	input file unit number
	pckmempaths	array of strings
	pakmovers	Array of package mover objects
