Member Function Documentation

void frepple::Buffer::beginElement ( XMLInput ,
const Attribute  
) [virtual]

Called while restoring the model from an XML-file.
This is called for each element within the "this" element, for which the "this" element is immediate parent.
It is called when the open element tag is encountered.

Reimplemented from frepple::utils::HasHierarchy< Buffer >.

Definition at line 266 of file buffer.cpp.

void frepple::Buffer::deleteOperationPlans ( bool  deleteLockedOpplans = false  ) 

Deletes all operationplans consuming from or producing from this buffer. The boolean parameter controls whether we delete also locked operationplans or not.

void frepple::Buffer::followPegging ( PeggingIterator iter,
FlowPlan curflowplan,
short  nextlevel,

const flowlist& frepple::Buffer::getFlows (  )  const [inline]

Returns a reference to the list of all flows of this buffer.

Definition at line 2949 of file model.h.

bool frepple::Buffer::getHidden (  )  const [inline, virtual]

Returns whether an entity is real or dummy.

Reimplemented from frepple::utils::Object.

Definition at line 2973 of file model.h.

Item* frepple::Buffer::getItem (  )  const [inline]

Returns the item stored in this buffer.

Definition at line 2876 of file model.h.

Location* frepple::Buffer::getLocation (  )  const [inline]

Returns the Location of this buffer.

Definition at line 2882 of file model.h.

CalendarDouble* frepple::Buffer::getMaximum (  )  const [inline]

Returns a pointer to a calendar for storing the maximum inventory level.

Definition at line 2893 of file model.h.

CalendarDouble* frepple::Buffer::getMinimum (  )  const [inline]

Returns a pointer to a calendar for storing the minimum inventory level.

Definition at line 2889 of file model.h.

double frepple::Buffer::getOnHand ( Date  d1,
Date  d2,
bool  min = true 
) const

Returns minimum or maximum available material on hand in the given daterange. The third parameter specifies whether we return the minimum (which is the default) or the maximum value. The computation is INclusive the start and end dates.

Definition at line 164 of file buffer.cpp.

double frepple::Buffer::getOnHand ( Date  d = Date::infinitePast  )  const

Returns the available material on hand immediately after the given date.

Definition at line 146 of file buffer.cpp.

Definition at line 2868 of file model.h.

virtual const MetaClass& frepple::Buffer::getType (  )  const [inline, virtual]

This returns the type information on the object, a bit similar to the standard type_info information.

Implements frepple::utils::Object.

Reimplemented in frepple::BufferDefault, frepple::BufferInfinite, and frepple::BufferProcure.

Definition at line 2975 of file model.h.

int frepple::Buffer::initialize (  )  [static]

Initialize the class.

Reimplemented in frepple::BufferDefault, frepple::BufferInfinite, and frepple::BufferProcure.

Definition at line 49 of file buffer.cpp.

int frepple::Buffer::setattro ( const Attribute attr,
const PythonObject field 
) [virtual]

Default setattro method.
Subclasses are expected to implement an override if the type supports settattro.

Reimplemented from frepple::utils::PythonExtensionBase.

Reimplemented in frepple::BufferProcure.

Definition at line 752 of file buffer.cpp.

void frepple::Buffer::setCarryingCost ( const double  c  )  [inline]

Return the carrying cost.
The cost of carrying inventory in this buffer. The value is a percentage of the item sales price, per year and per unit.
The default value is 0.0.

Definition at line 2912 of file model.h.

void frepple::Buffer::setHidden ( bool  b  )  [inline, virtual]

Mark the object as hidden or not. Hidden objects are not exported and are used only as dummy constructs.
