Constructor Details

Qualifiers

public Qualifiers(Domain domain,
 Qualifiers baseQualifiers)

Creates a new Qualifiers.

Parameters:

domain - a non-null Domain

baseQualifiers - a non-null Qualifiers

See Also:

• Qualifiers(Domain, org.microbean.assign.Qualifiers, AnnotationMirror)

Qualifiers

public Qualifiers(Domain domain,
 Qualifiers baseQualifiers,
 AnnotationMirror primordialMetaQualifier)

Creates a new Qualifiers.

Parameters:

domain - a Domain; may be null in which case primordialMetaQualifier must not be null

baseQualifiers - a non-null Qualifiers

primordialMetaQualifier - an AnnotationMirror identifying the primordial meta-qualifier; may be null in which case domain must be non-null

Throws:

NullPointerException - if baseQualifiers is null, or if domain is null in certain circumstances, or if primordialMetaQualifier is null in certain circumstances

Method Details

describeConstable

public Optional<? extends ConstantDesc> describeConstable()

Specified by:

describeConstable in interface Constable

primordialMetaQualifier

public final AnnotationMirror primordialMetaQualifier()

Returns the non-null, determinate AnnotationMirror representing the primordial meta-qualifier.

Returns:

the non-null, determinate AnnotationMirror representing the primordial meta-qualifier

primordialMetaQualifier

public final boolean primordialMetaQualifier(AnnotationMirror a)

Returns true if and only if the supplied AnnotationMirror is the same as the primordial meta-qualifier.

Parameters:

a - a non-null AnnotationMirror

Returns:

true if and only if the supplied AnnotationMirror is the same as the primordial meta-qualifier

Throws:

NullPointerException - if a is null

primordialMetaQualifiers

public final List<AnnotationMirror> primordialMetaQualifiers()

Returns a non-null, determinate, immutable List housing only the primordial meta-qualifier.

Returns:

a non-null, determinate, immutable List housing only the primordial meta-qualifier
