Constructor Detail

ExportProductConstraint

public ExportProductConstraint(int id)

Constructor calling the constructor of the ExportConstraint superclass.

Parameters:

id - The unique identifier for this constraint

Method Detail

setBaseTable

public void setBaseTable()

Sets the base table of this product constraint. This table is the domain of all paths included in this constraint.

Overrides:

setBaseTable in class ExportConstraint

setConstraintStrings

public void setConstraintStrings()

Sets the constraint strings for this constraint

Overrides:

setConstraintStrings in class ExportConstraint

2006-06-22 Vera Ranieri

setDeleteProc

private void setDeleteProc()

Sets the delete constraint string for this constraint.

Since:

2006-06-22 Vera Ranieri

setInsertProcs

private void setInsertProcs()

Sets the insert constraint strings for this constraint.

Since:

getFirstIfStatement

private java.lang.String getFirstIfStatement(ExportPath p)

Gets the first IF statement. This statement determines whether the tables which form the domains of the other paths involved in the product constraint contain items. The statement is true if all tables have at least one element.

Parameters:

p -

Returns:

The string containing the first IF statement.

getPathInsertStrings

private java.lang.String getPathInsertStrings(ExportPath p)

Gets the strings inserting an element for every table along the path up until the base table. Also sets the variable var to the last insert id.

Parameters:

p - The path upon which we need to insert

Returns:

The string of all the insert calls

getSecondIfStatement

private java.lang.String getSecondIfStatement(ExportPath p)

Gets the second IF statement. This statement checks if any elements need to be added along a secondary path, before elements are added into the base table.

Parameters:

p -

Returns:

The string of the second IF statement. If this statement is unneeded, returns the empty string

getInsertCall

private java.lang.String getInsertCall(ExportPath p)

Gets the actual INSERT SELECT string for the constraint.

Parameters:

p - The path for which this constraint applies

Returns:

The string of the statement inserting into the table.
