The metabase can be used to store test reports, reviews, coverage analysis reports, reports on static analysis of coding style, or anything else for which datatypes are constructed. .PP Metabase::Report is a base class for collections of Metabase::Fact objects that can be sent to or retrieved from a Metabase system. .PP Metabase::Report is itself a subclass of Metabase::Fact and offers the same \&\s-1API,\s0 except as described below. .SH "SUBCLASSING" .IX Header "SUBCLASSING" A subclass of Metabase::Report only requires one method, \f(CW"report_spec"\fR. .SH "ATTRIBUTES" .IX Header "ATTRIBUTES" \fIcontent\fR .IX Subsection "content" .PP The \f(CW\*(C`content\*(C'\fR attribute of a Report must be a reference to an array of Metabase::Fact subclass objects. .SH "METHODS" .IX Header "METHODS" In addition to the standard \f(CW\*(C`new\*(C'\fR constructor, the following \f(CW\*(C`open\*(C'\fR, \f(CW\*(C`add\*(C'\fR and \f(CW\*(C`close\*(C'\fR methods may be used to construct a report piecemeal, instead. .SS "open" .IX Subsection "open" .Vb 3 \& $report = Report::Subclass\->open( \& id => \*(AqAUTHORID/Foo\-Bar\-1.23.tar.gz\*(Aq, \& ); .Ve .PP Constructs a new, empty report. The 'id' attribute is required. The \&'refers_to' attribute is optional. The 'content' attribute may be provided, but see \f(CW\*(C`add\*(C'\fR below. No other attributes may be provided to \f(CW\*(C`new\*(C'\fR. .SS "add" .IX Subsection "add" .Vb 1 \& $report\->add( \*(AqFact::Subclass\*(Aq => $content ); .Ve .PP Using the 'id' attribute of the report, this method constructs a new Fact from a class and a content argument. The resulting Fact is appended to the Report's content array. .SS "close" .IX Subsection "close" .Vb 1 \& $report\->close; .Ve .PP This method validates the report based on all Facts added so far. .SS "facts" .IX Subsection "facts" This method returns a list of all the facts in the report. In scalar context, it returns the number of facts in the report. .SH "CLASS METHODS" .IX Header "CLASS METHODS" .SS "fact_classes" .IX Subsection "fact_classes" .SS "load_fact_classes" .IX Subsection "load_fact_classes" Loads each class listed in the report spec. .SH "ABSTRACT METHODS" .IX Header "ABSTRACT METHODS" Methods marked as 'required' must be implemented by a report subclass. (The version in Metabase::Report will die with an error if called.) .PP In the documentation below, the terms 'must, 'must not', 'should', etc. have their usual \s-1RFC 2119\s0 meanings. .PP Methods \s-1MUST\s0 throw an exception if an error occurs. .SS "report_spec" .IX Subsection "report_spec" \&\fBrequired\fR .PP .Vb 1 \& $spec = Report::Subclass\->report_spec; .Ve .PP The \f(CW\*(C`report_spec\*(C'\fR method \s-1MUST\s0 return a hash reference that defines how many Facts of which types must be in the report for it to be considered valid. Keys \s-1MUST\s0 be class names. Values \s-1MUST\s0 be non-negative integers that indicate the number of Facts of that type that must be present for a report to be valid, optionally followed by a '+' character to indicate that the report may contain more than the given number. .PP For example: .PP .Vb 4 \& { \& Fact::One => 1, # one of Fact::One \& Fact::Two => "0+", # zero or more of Fact::Two \& } .Ve .SH "BUGS" .IX Header "BUGS" Please report any bugs or feature using the \s-1CPAN\s0 Request Tracker. Bugs can be submitted through the web interface at .PP When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. .SH "AUTHORS" .IX Header "AUTHORS" .IP "\(bu" 4 David Golden .IP "\(bu" 4 Ricardo Signes .IP "\(bu" 4 H.Merijn Brand .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is Copyright (c) 2013 by David Golden. .PP This is free software, licensed under: .PP .Vb 1 \& The Apache License, Version 2.0, January 2004 .Ve
