Method Detail

findAll

public static java.util.Collection<NamedGraph> findAll(javax.servlet.http.HttpServletRequest request)
                                                throws javax.servlet.ServletException

Get an iterable collection of all known named graphs AND Contexts. If there is no Named Graph metadata for a Sesame context, its isManaged() method will return false. Note that named graphs are ONLY listed ONCE even if there is duplicate metadata.

Parameters:

request - a HttpServletRequest object.

Returns:

all named graphs in a Collection object.

Throws:

javax.servlet.ServletException - if any.

find

public static NamedGraph find(javax.servlet.http.HttpServletRequest request,
                              org.openrdf.model.URI name)
                       throws javax.servlet.ServletException

Returns a named graph object, or null if this is not a valid named graph OR context.

Parameters:

request - a HttpServletRequest object.

name - name of named-graph or context, a URI object.

Returns:

a NamedGraph object representing named graph, or null if no graph or context exists.

Throws:

javax.servlet.ServletException - if any.

find

public static NamedGraph find(javax.servlet.http.HttpServletRequest request,
                              org.openrdf.model.URI name,
                              boolean createp)
                       throws javax.servlet.ServletException

Returns a named graph object, or null if this is not a valid named graph OR context and createp was false.

Parameters:

request - a HttpServletRequest object.

name - name of named-graph or context, a URI object.

createp - a boolean, true if graph should be created

Returns:

a NamedGraph object representing named graph, or null if no graph or context exists UNLESS createp is true.

Throws:

javax.servlet.ServletException - if any.

getName

public org.openrdf.model.URI getName()

Getter for the field name.

Returns:

a URI object.

getLabel

public java.lang.String getLabel()

Getter for the field label.

getType

public NamedGraph.Type getType()

Getter for the field type.

Returns:

a URI object.

public org.openrdf.model.URI getTypeURI()

Getter for the field type, but returns URI form.

Returns:

a URI object.

getTypeLabel

public java.lang.String getTypeLabel()

Getter for the field typeLabel.

Returns:

a String object.

isAnonymousReadable

public boolean isAnonymousReadable()

Can be read by anonymous user (i.e. general public) if true.

Returns:

a boolean, true if graph is publically readable.
