module Bio::PDB::HeterogenFinder

methods to access heterogens (compounds or ligands)

XXX#each_chain must be defined.

Bio::PDB::HeterogenFinder is included by Bio::PDB::PDB, Bio::PDB::Model, and Bio::PDB::Chain.

Public Instance Methods

each_heterogen() { |heterogen| ... } click to toggle source

iterates over each heterogens

    # File lib/bio/db/pdb/utils.rb
388 def each_heterogen(&x) #:yields: heterogen
389   self.each_chain { |chain| chain.each_heterogen(&x) }
390 end

find_heterogen() { |heterogen| ... } click to toggle source

returns an array containing all heterogens for which given block is not false (similar to Enumerable#find_all).

    # File lib/bio/db/pdb/utils.rb
379 def find_heterogen
380   array = []
381   self.each_heterogen do |heterogen|
382     array.push(heterogen) if yield(heterogen)
383   end
384   return array
385 end

heterogens() click to toggle source

returns all heterogens

    # File lib/bio/db/pdb/utils.rb
393 def heterogens
394   array = []
395   self.each_chain { |chain| array.concat(chain.heterogens) }
396   return array
