Document Builder: how is rule detail loaded from DB to memory

this wiki gives a more detailed explanation regarding rule loading process as a complement for wiki "rule load process".

In our example we have ZCR_KT which has three different rules: ZCR_NAME, ZCR_RULE_TEST and ZCR_SWIM.

When the three rules are loaded into memory from database table, it looks like below:

And in the previous wiki "Rule load process", the column "EVALUATOR" is already filled as below. In wiki "rule evaluation process" we know that this column is the starting point of rule evaluation process.

How is it filled in the runtime?

it is filled by the static method /IPRO/CL_EVALUATION~load below:

one importing parameter is rule guid: 005056B23ADB1ED2B7F41E8C6D7CEB49

Through this guid we could get the rule header information from DB table /IPRO/TRULES:

Then read rule detail information from table SFOBUEV001 and pass the query result into constructor in line 27:

the content of lt_sfobuev001 looks like below in SE16:

all the build in function logic are also hard coded in this method:
