All Implemented Interfaces:

CommandHandler, EnvironmentHandler

public final class TabularHandler
extends Object
implements CommandHandler, EnvironmentHandler

Handles the (rather complex) tabular environment. It also handles the \\hline command. FIXME: This is legal inside $\mbox{...}$ so needs to output MathML in this case. Eeek!!! FIXME: No support for \vline and friends!!!

Method Detail

handleCommand

public void handleCommand(DOMBuilder builder,
                          Element parentElement,
                          CommandToken token)
                   throws SnuggleParseException

The command matched here is \\hline.

This case will have been dealt with explicitly by the tabular environment when used correctly so, if we end up here, then client has made a boo-boo.

Specified by:

handleCommand in interface CommandHandler

Parameters:

builder - DOMBuilder running this process, which provides access to convenience method for appending Nodes to the DOM

parentElement - parent Element that the resulting Nodes should (can) be added to

token - Token representing the command being processed.

Throws:

SnuggleParseException - to indicate a client error

handleEnvironment

public void handleEnvironment(DOMBuilder builder,
                              Element parentElement,
                              EnvironmentToken token)
                       throws SnuggleParseException

Description copied from interface: EnvironmentHandler

Called when a CommandToken is being handled by the DOMBuilder.

Specified by:

handleEnvironment in interface EnvironmentHandler

Parameters:

builder - DOMBuilder running this process, which provides access to convenience method for appending Nodes to the DOM

parentElement - parent Element that the resulting Nodes should (can) be added to

token - Token representing the environment being processed.

Throws:

SnuggleParseException

computeTableDimensions

protected static int[] computeTableDimensions(ArgumentContainerToken tableContent)

Computes the dimensions of the table by looking at its content.

Parameters:

tableContent - content of the tabular environment.

Returns:

{ rowCount, columnCount } pair
