public interface AuthorTableCellSpanProvider
extends Extension

This is an interface for classes which are responsible for providing information about the cell spanning. It should be implemented when the author extension being developed offers support for editing data in tabular form.

Method Summary

java.lang.Integer	getColSpan(AuthorElement cellElement) Get the number of columns the given cell spans across.
java.lang.Integer	getRowSpan(AuthorElement cellElement) Get the number of rows that the given cell spans across.
boolean	hasColumnSpecifications(AuthorElement tableElement) This method tells if the table contains column specifications.
void	init(AuthorElement tableElement) This method is called when starting to compute the layout for a table.

Method Detail

getColSpan

java.lang.Integer getColSpan(AuthorElement cellElement)

Get the number of columns the given cell spans across. For example, for the DocBook CALS tables the number of columns the cell spans across is computed by looking at the spanspec attribute. In case the spanspec attribute is missing then the column span is defined by the namest and nameend attribute.

Parameters:

cellElement - The node that represents a table cell in CSS.

Returns:

The number of columns this cell spans across (the minimum returned value must be 1) or null if not specified.

getRowSpan

java.lang.Integer getRowSpan(AuthorElement cellElement)

Get the number of rows that the given cell spans across. For example, for the DocBook CALS tables this value is computed by looking at the morerows attribute.

Parameters:

cellElement - The AuthorElement that represents a table cell in CSS.

Returns:

The number of rows this cell spans across (the minimum returned value must be 1) or null if not specified.

init

void init(AuthorElement tableElement)

This method is called when starting to compute the layout for a table. Its intended to extract information from the element representing the table only once, not on every getColSpan() or getRowSpan() call. Example: for a DocBook table we identify and cache the colspec and spanspec elements from that table. A new instance of the table cell span provider is used for every table in a document so cached data cannot be used between different tables..

Parameters:

tableElement - The AuthorElement representing a table (it has the CSS display property set on 'table').

hasColumnSpecifications

boolean hasColumnSpecifications(AuthorElement tableElement)

This method tells if the table contains column specifications. For example the CALS table model requires colspec elements to be present.

Parameters:

tableElement - The AuthorElement that is rendered as a table.

Returns:

true if some column specification info is present or if the table doesn't require any column specification info.
