the getCount method works out the number of "entries" for each report. E.g. if the report is "missing pages" and the method returns 3 then there are three "missing pages".

/**

|
|
*
|
|
* Creating reports
|
|
* ================
|
|
*
|
|
* Creating a new report is a matter overloading a few key methods
|
|
*
|
|
* {@link title()}: Return the title - i18n is your responsibility
|
|
* {@link description()}: Return the description - i18n is your responsibility
|
|
* {@link sourceQuery()}: Return a SS_List of the search results
|
|
* {@link columns()}: Return information about the columns in this report.
|
|
* {@link parameterFields()}: Return a FieldList of the fields that can be used to filter this
|
|
* report.
|
|
*
|
|
* If you wish to modify the report in more extreme ways, you could overload these methods instead.
|
|
*
|
|
* {@link getReportField()}: Return a FormField in the place where your report's TableListField
|
|
* usually appears.
|
|
* {@link getCMSFields()}: Return the FieldList representing the complete right-hand area of the
|
|
* report, including the title, description, parameter fields, and results.
|
|
*
|
|
* Showing reports to the user
|
|
* ===========================
|
|
*
|
|
* Right now, all subclasses of SS_Report will be shown in the ReportAdmin. In SS3 there is only
|
|
* one place where reports can go, so this class is greatly simplifed from from its version in SS2.
