Constructor Detail

EdgeTypeFilter

public EdgeTypeFilter(String... allowedPrefixTypes)

Creates a new EdgeTypeFilter with the given allowed edge prefix types.

Parameters:

allowedPrefixTypes - the allowed prefix types.

EdgeTypeFilter

public EdgeTypeFilter(Set<String> allowedPrefixTypes)

Creates a new EdgeTypeFilter with the given allowed edge prefix types.

Parameters:

allowedPrefixTypes - the allowed prefix types.

Method Detail

addListener

public void addListener(EdgeTypeFilter.Listener listener)

Adds a listener.

Parameters:

listener - the listener to add.

getAllowedPrefixTypes

public Set<String> getAllowedPrefixTypes()

Returns the set of allowed prefix types for edges.

Returns:

an unmodifiable set of allowed prefix types for edges.

getAllowedPostfixTypes

public Set<String> getAllowedPostfixTypes()

Returns the set of allowed postfix types for edges.

Returns:

an unmodifiable set of allowed postfix types for edges.

addAllowedPrefixType

public void addAllowedPrefixType(String type)

Adds an allowed prefix type. This causes the filter to accept edges with the given prefix type.

Parameters:

type - the allowed prefix type.

addAllowedPostfixType

public void addAllowedPostfixType(String type)

Adds an allowed prefix type. This causes the filter to accept edges with the given postfix type.

Parameters:

type - the allowed postfix type.

removeAllowedPrefixType

public void removeAllowedPrefixType(String type)

Disallows the given prefix type. This causes the filter to stop accepting edges with the given prefix type.

Parameters:

type - the prefix type to disallow.

removeAllowedPostfixType

public void removeAllowedPostfixType(String type)

Disallows the given postfix type. This causes the filter to stop accepting edges with the given postfix type.

Parameters:

type - the postfix type to disallow.

filterEdges

public Collection<Edge> filterEdges(Collection<Edge> original)

Filters out all edges that don't have an allowed prefix and postfix type.

Specified by:

filterEdges in class EdgeFilter

Parameters:

original - the original set of edges.

Returns:

the filtered set of edges.

EdgeFilter#filterEdges(Collection)

allowsPrefix

public boolean allowsPrefix(String type)

Does the filter allow the given prefix.

Parameters:

type - the type to check whether it is allowed as prefix.

Returns:

true iff the given type is allowed as prefix.

allowsPostfix

public boolean allowsPostfix(String type)

Does the filter allow the given postfix.

Parameters:

type - the type to check whether it is allowed as postfix.

Returns:

true iff the given type is allowed as postfix.
