Method Detail

hasForeignKeysRow

public static boolean hasForeignKeysRow(ILogicalTable dataTable)

Foreign keys row is optional for data table. It consists reference for field value to other table. Foreign keys always starts from 62 symbol.

Parameters:

dataTable - data table to check

Returns:

TRUE if second row in data table body (next to the field row) consists even one value, in any column, starts with 62 symbol.

getTableBody

public static ILogicalTable getTableBody(TableSyntaxNode tsn)

Gets the table body, by skipping the table header and properties sections.

Parameters:

tsn - inspecting table

Returns:

Table body without table header and properties section.

public static boolean isHorizontalTable(ILogicalTable dataTableBody,
                                        IOpenClass tableType)

Checks if table representation is horizontal. Horizontal is data table where parameters are listed from left to right.
Example:

param1	param2	param3
param1 value	param2 value	param3 value

Parameters:

dataTableBody - the body of a table to check

tableType - the type of data table

Returns:

TRUE if table is horizontal.

public static ILogicalTable getHorizontalTable(ILogicalTable tableBody,
                                               IOpenClass tableType)

Gets the horizontal table representation from current table. If it was vertical it will be transposed.

Parameters:

tableBody - the body of a table to check

tableType - the type of data table

Returns:

Horizontal representation of table.

getHorizontalDataWithTitle

public static ILogicalTable getHorizontalDataWithTitle(ILogicalTable horizDataTableBody)

Gets the Data_With_Titles rows from the data table body. Data_With_Titles start row consider to be the next row after descriptor section of the table and till the end of the table.

Parameters:

horizDataTableBody - Horizontal representation of data table body.

Returns:

Data_With_Titles rows for current data table body.

getSubTableForBusinessView

public static ILogicalTable getSubTableForBusinessView(ILogicalTable tableBody,
                                                       IOpenClass tableType)

Gets the sub table for displaying on business view.

Parameters:

tableBody - data table body.

tableType - the type of a table

Returns:

Data_With_Titles section for current data table body.

getDescriptorRows

public static ILogicalTable getDescriptorRows(ILogicalTable horizDataTableBody)

Gets the descriptor rows from the data table body. Descriptor rows are obligatory parameter row and optional foreign key row if it exists in the table.

Parameters:

horizDataTableBody - Horizontal representation of data table body.

Returns:

Descriptor rows for current data table body.

makeColumnTitle

public static StringValue makeColumnTitle(IBindingContext bindingContext,
                                          ILogicalTable dataWithTitleRows,
                                          int column,
                                          boolean hasColumnTitleRow)

Gets title for column if required or returns blank value.

Parameters:

dataWithTitleRows - Logical part of the data table. Consider to include all rows from base table after header section (consists from header row + property section) and descriptor section (consists from JavaBean name obligatory + optional index row, see hasForeignKeysRow(ILogicalTable)).
This part of table may consists from optional first title row and followed data rows.
