Method Detail

getEdges

public java.util.LinkedList<ExportEdge> getEdges()

Getter method for the linked list of edges contained in this path.

Returns:

The linked list of edges for this path

addEdge

public void addEdge(ExportEdge e)

Adds an edge to the path. Builds the path according to the order they are stored in the XML file.

Parameters:

e - The edge to be added to the end of the path

getName

public java.lang.String getName()

Returns the unique name of this path, created by the edges contained in this path.
Example: If a path contains edges e1, e2, e3 in that order, the name of the path is taken to be e1;e2;e3 .

Returns:

The name of this path

getDomain

public java.lang.String getDomain()

Returns the domain of the first edge in the edge collection of the path, and thus the domain of the path.

Returns:

The domain of the path

Since:

2006-05-22

getCoDomain

public java.lang.String getCoDomain()

Returns the codomain of the last edge in the edge collection of the path, and thus the codomain of the path.

Returns:

The codomain of the path

getAllTablesString

public static java.lang.String getAllTablesString(ExportPath path)

Determines the tables along a path, and formats them into a string.

Parameters:

path - The path for which the tables must be determined

Returns:

A string for SQL containing a list of all tables involved in the path.

getDelConditions

public static java.lang.String getDelConditions(ExportPath path)

Determines the initial condition, as required by a BEFORE DELETE procedure. Once initial condition is determined, all other conditions are then determined.

Parameters:

path - The path for which the delete conditions need to be determined

Returns:

String of the delete conditions

Since:

2006-06-20, Vera Ranieri

getConditions

public static java.lang.String getConditions(ExportPath path)

Gets the conditions for a path. These conditions are determined by matching unique ids along the path.

Parameters:

path - The path for which an element needs to be deleted from the codomain.

Returns:

A string of the conditions.
