Method Detail

setGraphProperties

public static void setGraphProperties(Object target,
                                      Graph g)

Simultaneously set all graph properties (i.e. all fields implementing interface Graph) of a target object

Parameters:

target - the object where all graph properties shall be set

g - the graph to set

getGraphProperty

public static Graph getGraphProperty(Graph origG,
                                     Class<?> wantedProp)

Get a given property for a graph if the graph (or one if its nested graphs) has this property. Otherwise null is returned.

Parameters:

origG - the graph for which the property shall be returned

wantedProp - the desired property

Returns:

the graph with the given property or null if the property is not available

requireGraphProperty

public static Graph requireGraphProperty(Graph origG,
                                         Class wantedProp)

Convert a graph to a given property. Throws an exception if this is not possible.

Parameters:

origG - the graph for which the property shall be returned

wantedProp - the desired property

Returns:

the graph with the given property

Throws:

UnsupportedGraphProperty - thrown if the graph does not possess the given property.
