NAME

Bio::Structure::Entry - Bioperl structure Object, describes the whole entry

SYNOPSIS

#add synopsis here

DESCRIPTION

This object stores a whole Bio::Structure entry. It can consist of one or more models (Bio::Structure::Model), which in turn consist of one or more chains (Bio::Structure::Chain). A chain is composed of residues (Bio::Structure::Residue) and a residue consists of atoms (Bio::Structure::Atom). If no specific model or chain is chosen, the first one is chosen.

Title   : connect
Usage   : 
Function: Alias to conect()
Returns : 
Args    : 

conect()

Title   : conect
Usage   : $structure->conect($source);
Function: Get/set method for conect
Returns : A list of serial numbers for Atoms connected to source
	        (together with $entry->get_atom_by_serial($model, $serial),
          this should be OK for now)
Args    : The source, the serial number for the source Atom, and the type

get_all_connect_source

Args    : 
Notes   : This is a bit of a kludge, but it is the best for now. Conect info might need
	        to go in a separate object

master()

_create_default_model()

Title   : _create_default_model

Returns : 
Args    : 

_create_default_chain()

Title   : _create_default_chain

	        in an X-ray structure where there is only one chain
Returns :

_parent()

 Title   : _parent
 Usage   : This is an internal function only. It is used to have one 
 	        place that keeps track of which object has which other object 
	        as parent. Thus allowing the underlying modules (Atom, Residue,...)
	        to have no knowledge about all this (and thus removing the possibility
	        of reference cycles).
	        This method hides the details of manipulating references to an anonymous
	        hash.
 Function: To get/set an objects parent 
 Returns : A reference to the parent if it exist, undef otherwise. In the 
 	        current implementation each node should have a parent (except Entry).
 Args    : 

_child()

 Title   : _child
 Usage   : This is an internal function only. It is used to have one 
 	        place that keeps track of which object has which other object 
	        as child. Thus allowing the underlying modules (Atom, Residue,...)
	        to have no knowledge about all this (and thus removing the possibility
	        to have no knowledge about all this (and thus removing the possibility
	        of reference cycles).
	        This method hides the details of manipulating references to an anonymous
 	        hash.
 Function: To get/set an the children of an object 
 Returns : A reference to an array of child(ren) if they exist, undef otherwise. 
 Args    : 

_remove_from_graph()

 Title   : _remove_from_graph
 Usage   : This is an internal function only. It is used to remove from
 	        the parent/child graph. We only remove the links from object to
	        his parent. Not the ones from object to its children.
 Function: To remove an object from the parent/child graph
 Returns : 
 Args    : The object to be orphaned
