Method Summary

Projection	createProjection(java.lang.String name, Concept source, Concept target, java.util.Set<Evidence> evidence) Create a new projection in this mapping between concepts source and target with the specified name (optional operation).
Authority	getAuthority() Return the authority for this mapping.
java.util.Set<Projection>	getProjections() Return the set of all projections in this mapping.
Domain	getSource() Return the source domain of this mapping.
Domain	getTarget() Return the target domain of this mapping.

Method Detail

getSource

Domain getSource()

Return the source domain of this mapping. The source domain must not be null.

Returns:

the source domain

getTarget

Domain getTarget()

Return the target domain of this mapping. The target domain must not be null.

Returns:

the target domain

getProjections

java.util.Set<Projection> getProjections()

Return the set of all projections in this mapping. The set must not be null, but may be empty.

Returns:

the set of all projections

getAuthority

Authority getAuthority()

Return the authority for this mapping. The authority must not be null.

Returns:

the authority

createProjection

Projection createProjection(java.lang.String name,
                            Concept source,
                            Concept target,
                            java.util.Set<Evidence> evidence)

Create a new projection in this mapping between concepts source and target with the specified name (optional operation). The source concept must be within the source domain of this mapping, and the target domain must be within the target domain of this mapping. Only one projection may exist between the same source and target with the same name within this mapping. The source and target concepts must not be null.

Parameters:

name - projection name

source - projection source concept

target - projection target concept

evidence - set of evidence

Returns:

new projection

Throws:

java.lang.UnsupportedOperationException - if the createProjection method is not supported by this Mapping
