Interface Atom

All Superinterfaces:

Cloneable, PDBRecord

All Known Implementing Classes:

AtomImpl

public interface Atom
extends Cloneable, PDBRecord

A simple interface for an Atom. The coordinates can be accessed via the getCoords(), or the getX(), getY(), getZ() methods. There are a few additional methods here to provide some PDB specific information.

Method Detail

setName

void setName(String s)

Set atom name, e.g. "CA".

Parameters:

s - a trimmed String specifying the name value

See Also:

getName()

getName

String getName()

Get atom name, e.g. "CA". Beware that some PDB atom names are ambiguous (e.g. CA, which means C-alpha or Calcium), the ambiguity can simply be resolved by also checking the element with getElement()

Returns:

a trimmed String representing the name value
