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.

FEEDBACK ^

Mailing Lists

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

_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
