                       int height)
                throws CreateTableException

Description copied from class: TableBuilder

Begins writing a table.

Overrides:

beginTable in class TableBuilder

Parameters:

width - table width in cells

height - table height in cells

Throws:

CreateTableException - if unable to create table

endTable

public void endTable()
              throws CreateTableException

Description copied from class: TableBuilder

String located	String statelist
Located	State

Here element's title is C2, logic is located == "in" && statelist.indexOf( di.driver.state) >= 0, parameterNames are Located and State and finally parameterSignatures are String located and String statelist.

The lengths of parameterNames and parameterSignatures must be equal and positive.

Parameters:

title - element title

logic - element logic

parameterNames - array of element parameter names

parameterSignatures - array of element parameter signatures

writeHeader

public void writeHeader(String signature)

Writes decision table header.
Requires the header signature, e.g. void hello1(int hour)
without Decision table header token Rules
