Constructor Summary

ConfigurationPointImpl()

Method Summary

void	addContribution(Contribution c)
boolean	areElementsMappable() Returns true if the elements contributed to this configuration point can be retrieved as a Map.
protected void	extendDescription(ToStringBuilder builder) Implemented in subclasses to provide details about subclass properties.
int	getContributionCount() Returns the number of contributions; it is expected that each top-level Element in each Contribution will convert to one element instance; the value returned is the total number of top-level elements in all contributed Extensions.
Schema	getContributionsSchema() Returns the Schema for contributions to the configuration point (which may be null if the point does not define a schema for contributions).
java.util.List	getElements() Returns the contributed elements as an unmodifiable List.
java.util.Map	getElementsAsMap() Returns the contributed elements as an unmodifiable Map.
Occurances	getExpectedCount()
Schema	getSchema()
void	setContributionsSchema(Schema schema)
void	setExpectedCount(Occurances occurances)
void	setShutdownCoordinator(ShutdownCoordinator coordinator)

public ConfigurationPointImpl()

Method Detail

extendDescription

protected void extendDescription(ToStringBuilder builder)

Description copied from class: AbstractExtensionPoint

Implemented in subclasses to provide details about subclass properties.

Specified by:

extendDescription in class AbstractExtensionPoint

getContributionCount

public int getContributionCount()

Returns the number of contributions; it is expected that each top-level Element in each Contribution will convert to one element instance; the value returned is the total number of top-level elements in all contributed Extensions.

addContribution

public void addContribution(Contribution c)

getExpectedCount

public Occurances getExpectedCount()

setExpectedCount

public void setExpectedCount(Occurances occurances)

getElements

public java.util.List getElements()

Returns the contributed elements as an unmodifiable List. Internally, a proxy to the real list is returned, such that the real list may not be constructed until actually needed.

Specified by:

getElements in interface ConfigurationPoint

areElementsMappable

public boolean areElementsMappable()

Description copied from interface: ConfigurationPoint

Returns true if the elements contributed to this configuration point can be retrieved as a Map. The contributions in the map are keyed on an attribute as specified by the contributions schema. Thus, as a requirement, this configuration point must have a defined schema, which in turn must support keying of all valid instances.

Specified by:

areElementsMappable in interface ConfigurationPoint

getElementsAsMap

public java.util.Map getElementsAsMap()

Returns the contributed elements as an unmodifiable Map. Internally, a proxy to the real map is returned, such that the real map may not be constructed until actually needed.

Specified by:

getElementsAsMap in interface ConfigurationPoint

getSchema

public Schema getSchema()

setContributionsSchema

public void setContributionsSchema(Schema schema)

getContributionsSchema

public Schema getContributionsSchema()

Description copied from interface: ConfigurationPoint

Returns the Schema for contributions to the configuration point (which may be null if the point does not define a schema for contributions).

Specified by:

getContributionsSchema in interface ConfigurationPoint

setShutdownCoordinator

public void setShutdownCoordinator(ShutdownCoordinator coordinator)
