Method Details

newInstance

static LowestCommonAncestorOffline.IQueries newInstance(IntGraph g)

Create an empty queries container.

Parameters:

g - the graph

Returns:

a new queries container

addQuery

void addQuery(int u,
 int v)

Add a query for the lowest common ancestor of u and v.

Parameters:

u - the first vertex

v - the second vertex

addQuery

@Deprecated
default void addQuery(Integer u,
 Integer v)

Deprecated.

Please use addQuery(int, int) instead to avoid un/boxing.

Add a query for the lowest common ancestor of u and v.

Specified by:

addQuery in interface LowestCommonAncestorOffline.Queries<Integer,Integer>

Parameters:

u - the first vertex

v - the second vertex

getQuerySourceInt

int getQuerySourceInt(int idx)

Get a query source by index.

A query is composed of two vertices, the source and the target. This method return the source vertex of a query. Use getQueryTargetInt(int) to get the target vertex.

Parameters:

idx - index of the query. Must be in range [0, size())

Returns:

the first vertex of the query

Throws:

IndexOutOfBoundsException - if idx < 0 or idx >= size()

getQuerySource

@Deprecated
default Integer getQuerySource(int idx)

Deprecated.

Please use getQuerySourceInt(int) instead to avoid un/boxing.

Get a query source by index.

A query is composed of two vertices, the source and the target. This method return the source vertex of a query. Use LowestCommonAncestorOffline.Queries.getQueryTarget(int) to get the target vertex.

Specified by:

getQuerySource in interface LowestCommonAncestorOffline.Queries<Integer,Integer>

Parameters:

idx - index of the query. Must be in range [0, size())

Returns:

the first vertex of the query

getQueryTargetInt

int getQueryTargetInt(int idx)

Get a query target by index.

A query is composed of two vertices, the target and the source. This method return the target vertex of a query. Use getQueryTargetInt(int) to get the source vertex.

Parameters:

idx - index of the query. Must be in range [0, size())

Returns:

the second vertex of the query

Throws:

IndexOutOfBoundsException - if idx < 0 or idx >= size()

getQueryTarget

@Deprecated
default Integer getQueryTarget(int idx)

Deprecated.

Please use getQueryTargetInt(int) instead to avoid un/boxing.

Get a query target by index.

A query is composed of two vertices, the target and the source. This method return the target vertex of a query. Use LowestCommonAncestorOffline.Queries.getQueryTarget(int) to get the source vertex.

Specified by:

getQueryTarget in interface LowestCommonAncestorOffline.Queries<Integer,Integer>

Parameters:

idx - index of the query. Must be in range [0, size())

Returns:

the second vertex of the query
