Method Detail

evaluate

public SubmitRecord evaluate()

Evaluate the submit rules.

Returns:

SubmitRecord returned from the evaluated rules. Can include errors.

resultsToSubmitRecord

public SubmitRecord resultsToSubmitRecord(com.googlecode.prolog_cafe.lang.Term submitRule,
                                          List<com.googlecode.prolog_cafe.lang.Term> results)

Convert the results from Prolog Cafe's format to Gerrit's common format.

can_submit/1 terminates when an ok(P) record is found. Therefore walk the results backwards, using only that ok(P) record if it exists. This skips partial results that occur early in the output. Later after the loop the out collection is reversed to restore it to the original ordering.

getSubmitType

public SubmitTypeRecord getSubmitType()

Evaluate the submit type rules to get the submit type.

Returns:

record from the evaluated rules.
