Constructor.

Method Details

getFailoverDataConnectorId

@Nullable
public String getFailoverDataConnectorId()

Gets the ID of the AbstractDataConnector whose values will be used in the event that this data connector experiences an error.

Specified by:

getFailoverDataConnectorId in interface DataConnector

Returns:

ID of the AbstractDataConnector whose values will be used in the event that this data connector experiences an error

setFailoverDataConnectorId

public void setFailoverDataConnectorId(@Nullable
 String id)

Set the ID of the AbstractDataConnector whose values will be used in the event that this data connector experiences an error.

Parameters:

id - ID of the AbstractDataConnector whose values will be used in the event that this data connector experiences an error

setLastSuccess

public void setLastSuccess(@Nullable
 Instant time)

Set the time when this connector last worked.

Parameters:

time - what to set

Since:

4.1.0

getLastSuccess

@Nullable
public Instant getLastSuccess()

Get the time when this connector last succeeded. TODO: Remove default in V5.

Specified by:

getLastSuccess in interface DataConnector

Returns:

when it last succeeded

setLastFail

public void setLastFail(@Nullable
 Instant time)

Set the time when this connector last failed.

Parameters:

time - what to set

getLastFail

@Nullable
public Instant getLastFail()

Get the time when this connector last failed. This will be set for any exception regardless of the setting of ResolverPlugin.isPropagateResolutionExceptions()

Specified by:

getLastFail in interface DataConnector

Returns:

when it last failed

setNoRetryDelay

public void setNoRetryDelay(@Nonnull
 Duration delay)

Set how long to wait until we declare the connector (potentially) alive again.

Parameters:

delay - what to set

getNoRetryDelay

@Nonnull
public Duration getNoRetryDelay()

Get how long to wait until we declare the connector (potentially) alive again.

Specified by:

getNoRetryDelay in interface DataConnector

Returns:

how long to wait.

setExportAttributes

public void setExportAttributes(@Nonnull
 Collection<String> what)

Sets the list of attribute names to export during resolution.

Parameters:

what - the list

getExportAttributes

@Nonnull
@Unmodifiable
@NotLive
public Collection<String> getExportAttributes()

Gets the list of attribute names to export during resolution.

Specified by:

getExportAttributes in interface DataConnector

Returns:

the list of attribute names to export during resolution

doInitialize

protected void doInitialize()
                     throws ComponentInitializationException

Overrides:

doInitialize in class AbstractIdentifiedInitializableComponent

Throws:

ComponentInitializationException

doResolve

@Nullable
@Unmodifiable
@NotLive
public final Map<String,IdPAttribute> doResolve(@Nonnull
 AttributeResolutionContext resolutionContext,
 @Nonnull
 AttributeResolverWorkContext workContext)
                                         throws ResolutionException

Perform the actual resolution. The resolved attribute(s) should not be recorded in the work context. This method delegates to doDataConnectorResolve(AttributeResolutionContext, AttributeResolverWorkContext). It serves as a future extension point for introducing new common behavior.

Specified by:

doResolve in class AbstractResolverPlugin<Map<String,IdPAttribute>>

Parameters:

resolutionContext - current resolution context

workContext - child context where intermediate results are tracked

Returns:

the resolved attributes or null if no attributes were resolved

Throws:

ResolutionException - thrown if there is a problem resolving the attributes

• AbstractResolverPlugin.resolve(AttributeResolutionContext)

doDataConnectorResolve

@Nullable
@Unmodifiable
@NotLive
protected abstract Map<String,IdPAttribute> doDataConnectorResolve(@Nonnull
 AttributeResolutionContext resolutionContext,
 @Nonnull

                                                            throws ResolutionException

Retrieves a collection of attributes from some data source.

Parameters:

resolutionContext - current resolution context

workContext - current resolver work context

Returns:

collected attributes indexed by attribute ID

Throws:

ResolutionException - thrown if there is a problem resolving the attributes

getLogPrefix

@Nonnull
@NotEmpty
protected String getLogPrefix()

Return a string which is to be prepended to all log messages.

Specified by:

getLogPrefix in class AbstractResolverPlugin<Map<String,IdPAttribute>>
