Enum NamedGraphType

java.lang.Object
  java.lang.Enum<NamedGraphType>
      org.eaglei.repository.model.NamedGraphType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<NamedGraphType>

@HasContentCache
public enum NamedGraphType
extends java.lang.Enum<NamedGraphType>

This class is both an enumeration and an ImmutableObjectModel representing the allowable Types of Named Graphs. Although the types of named graphs are part of the repository's internal ontology and thus appear that they might be "easily" changed, in reality, the semantics of named graph types are thoroughly baked into the repo logic such that if they are changed or extended, updating this enum is the least of the work required. The symbolic name is also how the named graph type appears in the API, at least, where a keyword is used instead of the URI.

Method Detail

values

public static NamedGraphType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NamedGraphType c : NamedGraphType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NamedGraphType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

decache

public static void decache()

Invalidate the NGT cache, called when RDF has changed.

getURI

public org.openrdf.model.URI getURI()

Accessor

parse

public static NamedGraphType parse(java.lang.String v)

Interpret string as one of the enumerated type names

parse

public static NamedGraphType parse(org.openrdf.model.URI v)

Interpret URI as one of the enumerated type names

getLabel

public java.lang.String getLabel()

Get pretty title to include in e.g. a menu

find

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

Get NGT from the fixed map, we do not expect to update the ontology.

Throws:

javax.servlet.ServletException

findAll

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

Get list of all types. Almost never gets called, so inefficient implementation is ok

Throws:

javax.servlet.ServletException
