definition_parser

The model definition parser object “DefinitionParser” instantiates Models and Genes objects from XML model definitions (see Macromolecular models). The parsing consists in three phases.

Phase 1.

• For each model to parse
  • create the Model
  • add this Model to the model_bank
  • findall genes defined in this model what are the level in the model definition.
  • create the CoreGene (a Gene which is not bind to a model). For each gene name there is only one instance of CoreGene
  • add these CoreGene in the gene_bank

Phase 2.

• For each model to search

  • For each Gene defined in this System:

    • link the gene to the model. Create a ModelGene by encapsulating CoreGene from the gene_bank It can exists at each run several ModelGene for one CoreGene
    • If a gene has exhangeables create them (an Exchangeable inherits from ModeleGene) and add them to the current ModelGene

For instance:

Syst_1
<system inter_gene_max_space="10">
    <gene name=”A” mandatory=”1” loner="1">
        <exchangeables>
            <gene name=”B”>
        </exchangeables>
    </gene>
<system>

Syst_2
<system inter_gene_max_space="15">
    <gene name=”B” mandatory=”1”>
        <exchangeables>
            <gene name=”C”>
        </exchangeables>
    </gene>
<system>

Syst_3
<system inter_gene_max_space="20">
    <gene name=”c” mandatory=”1” />
<system>

With the example above:

• the CoreGene A, B, C will be created
• the ModelGene (Syst_1, A) (Syst_1, B), (Syst_2, B), (Syst_2, C), (Syst_3, C)
• The ModeleGene (Syst_1, A), (Syst_2, B) and (Syst_3, C) are directly link to their respective Models
• and where (Syst_1, B) (Syst_2, C) are exchangeables and link respectively to (Syst_1, A) and (Syst_2, B)
• the ModelGene has attributes defined in the model where they appear (Syst_1, B) inter_gene_max_space=”10” (Syst_2, B) inter_gene_max_space=”15”

Note

The only “full” Systems (i.e., with all corresponding Genes created) are those to detect.
