libsbml.DateList Class Reference

Inheritance diagram for libsbml.DateList:

Detailed Description

Class for managing lists of Date objects.

This class of objects is defined by libSBML only and has no direct equivalent in terms of SBML components. This class is not prescribed by the SBML specifications, although it is used to implement features defined in SBML.

This class is necessary because of programming language differences between Python and the underlying C++ core of libSBML's implementation. It would of course be preferable to have a common list type for all lists returned by libSBML (e.g., lists of Date objects, lists of Date objects, etc.). However, this is currently impossible to achieve given the way the underlying C++ lists are implemented.

As a result of this incompatibility, libSBML must implement the Python versions of the lists in another way. The approach taken is to define specialized list types for each kind of object that needs a list; that is, DateList for Date objects, DateList for Date objects, and a few others. These list objects provide the same kind of functionality that the underlying C++ generic lists provide (such as get(), add(), remove(), etc.).

Constructor & Destructor Documentation

def libsbml.DateList.__init__

(

self

)

Explicit constructor for this list.

__init__()   string

In most circumstances, callers will obtain an DateList object from a call to a libSBML method that returns the list. However, the constructor is provided in case callers need to construct the lists themselves.

Member Function Documentation

def libsbml.DateList.add	(		self,
			args
	)

Adds the given Date object item to this list.

add(Date item)

Parameters

item	the Date object to add to add

def libsbml.DateList.get	(		self,
			args
	)

Returns the nth Date object from this list.

get()   Date

If the index number n is greater than the size of the list (as indicated by getSize()), then this method returns None.

Parameters

n	the index number of the item to get, with indexing beginning at number 0.

Returns

the nth item in this DateList items.

getSize()

def libsbml.DateList.getSize

(

self

)

Returns the number of items in this list.

getSize()   long

Returns

the number of elements in this list.

def libsbml.DateList.prepend	(		self,
			args
	)

Adds the Date object item to the beginning of this list.

prepend(Date item)

Parameters

item	a pointer to the item to be prepended.

def libsbml.DateList.remove	(		self,
			args
	)

Removes the nth Date object from this list and returns it.

remove(long n)   Date

Callers can use getSize() to find out the length of the list. If n > getSize(), this method returns None and does not delete anything.

Parameters

n	the index number of the item to remove

Returns

the item indexed by n
