public class DescriptorBuilder

extends TransformerStack

Interface for outputting Report metadata in order to dynamically build a stylesheet.

Although a given report can be rendered by a static stylesheet, the limitations of XSL make it difficult to create a single stylesheet that will render a large variety of different reports. For instance, simple tasks like hiding a column of data require either that the name of the column be hardwired into the stylesheet, or that we use some non-standard XSL features. We solve this problem instead by defining a report metadata language that can be rendered into a stylesheet using XSL. In essence, we use a meta-stylesheet to create stylesheets from Report meta-data.

This might seem over-complicated but it has the huge advantage that our generated stylesheets can be relatively simple, and so (hopefully) mutually compatible across different implementations. This in turn will allow us to use client-side XSLT on IE 6 and NS 6

Method Detail

startReportDescriptor

public void startReportDescriptor(java.lang.String class_id,
                                  org.jdaemon.util.AttributeList attributes)

Begin a report-descriptor element

A report-descriptor element describes a report of a particular class. In principle, a report-descriptor with a class 'myreport' should accurately describe all reports with class 'myreport'.

A report-descriptor may contain either one of the following: a group-descriptor element a sort-descriptor element The former being the case when the report contains totals for all the data presented and the latter being the case when only group totals are present.

---

endReportDescriptor

public void endReportDescriptor()

End a report-descriptor element.

---

startGroupDescriptor

public void startGroupDescriptor(org.jdaemon.util.AttributeList attributes)

Begin a group-descriptor element

A group-descriptor element describes data with associated totals

A group-descriptor may contain: a sort-descriptor element to describe the way data within this group is sorted row-descriptor elements to describe total and data rows. Typically a grouping descriptor will either contain a sort-descriptor (for sorts and sub-groupings) and a row-descriptor (for totals), or it will contain two row-descriptors, one for the bulk data and one for the totals.

---

endGroupDescriptor

public void endGroupDescriptor()

End a grouping-descriptor element.

---

startSortDescriptor

public void startSortDescriptor(java.lang.String class_id,
                                org.jdaemon.util.AttributeList attributes)

Begin a sort-descriptor element

A sort-descriptor element describes the ordering and aggregation of rows

A sort-descriptor may contain either of the following: a sort-descriptor element describing sub-sorts a group-descriptor to describe data and associated totals

---

endSortDescriptor

public void endSortDescriptor()

End a sort-descriptor element

---

startRowDescriptor

public void startRowDescriptor(java.lang.String class_id,
                               org.jdaemon.util.AttributeList attributes)

Begin a row-descriptor element

A row-descriptor element describes rows within a report of a particular class.

A row-descriptor may contain: cell-descriptor elements to describe the cells within the row

---

endRowDescriptor

public void endRowDescriptor()

End a row-descriptor element

---

startCellDescriptor

public void startCellDescriptor(java.lang.String class_id,
                                org.jdaemon.util.AttributeList attributes)

Begin a cell-descriptor element

A cell-descriptor element describes cells within a report of a particular class.

---

endCellDescriptor

public void endCellDescriptor()

End a cell-descriptor element
