Field Detail

MY_URI

public static final String MY_URI

PROP_CONTEXT_PROVIDED_EVENTS

public static final String PROP_CONTEXT_PROVIDED_EVENTS

An array of ContextEventPatterns each of which declares a class of context events that the provider provides.

PROP_CONTEXT_PROVIDER_TYPE

public static final String PROP_CONTEXT_PROVIDER_TYPE

The type of a context provider. The range is ContextProviderType.

PROP_CONTEXT_SOURCE

public static final String PROP_CONTEXT_SOURCE

The underlying device(s) used by a context provider to determine the state of the provided context elements. The range is ManagedIndividual.

Constructor Detail

ContextProvider

public ContextProvider()

ContextProvider

public ContextProvider(String uri)

ContextProvider

protected ContextProvider(String uriPrefix,
                          int numProps)

Method Detail

getClassURI

public String getClassURI()

Description copied from class: ManagedIndividual

Get the class URI for this ManagedIndividual. All non-abstract subclasses MUST overwrite this method!

Overrides:

getClassURI in class ManagedIndividual

Returns:

The class URI.

getContextSources

public ManagedIndividual[] getContextSources()

Returns the list of devices used by this context provider.

getPropSerializationType

public int getPropSerializationType(String propURI)

The type of a context provider should be of minor interest, whereas the source could be important; but even the latter can be represented in its reduced form.

Specified by:

getPropSerializationType in class ManagedIndividual

See Also:

ManagedIndividual.getPropSerializationType(String)

getProvidedEvents

public ContextEventPattern[] getProvidedEvents()

Returns the classes of context events provided by this context provider.

getProviderType

public ContextProviderType getProviderType()

isWellFormed

public boolean isWellFormed()

Description copied from class: Resource

Returns true, if the state of the resource is valid, otherwise false.

Subclasses should overwrite this methods as the default implementation returns always true.

Overrides:

isWellFormed in class ManagedIndividual

See Also:

ManagedIndividual.isWellFormed()

setContextSources

public boolean setContextSources(ManagedIndividual[] sources)

Allows to assign a set of ManagedIndividuals as the origin of the Context Information provided by this ContextProvider.

Parameters:

sources - An Array of ManagedIndividuals representing the source of context events that generate the actual information provided by this ContextProvider.

setProperty

public boolean setProperty(String propURI,
                           Object value)

Description copied from class: ManagedIndividual

The default implementation that will set a property if it was not set before and the given value complies with the restrictions defined by this class of managed individuals for the given propURI.

Overrides:

setProperty in class ManagedIndividual

Returns:

true if the property changed as a result of the call

See Also:

Resource.setProperty(java.lang.String, java.lang.Object)

setProvidedEvents

public boolean setProvidedEvents(ContextEventPattern[] myEvents)

Allows to assign a set of ContextEventPatterns as the classes of context events provided by this ContextProvider.

Parameters:

myEvents - An Array of ContextEventPatterns describing the context events provided by this ContextProvider.

setType

public boolean setType(ContextProviderType type)

Set the type of this ContextProvider to one of those defined in ContextProviderType.

Parameters:

type - The ContextProviderType of the ContextProvider.
