public abstract class AbstractAnnotationValues
extends Object

Abstract class that provides a convenience parser and holder for annotation values. Useful if an add-on needs to share annotation parsing outcomes between its provider and metadata instances.

Field Summary

protected AnnotationMetadata	annotationMetadata
protected boolean	classParsed Indicates whether the class was able to be parsed at all (ie the metadata was properly formed)

protected	AbstractAnnotationValues(MemberHoldingTypeDetailsMetadataItem<?> governorMetadata, Class<?> annotationType) Convenience constructor that takes a Class for the annotation type
protected	AbstractAnnotationValues(MemberHoldingTypeDetailsMetadataItem<?> governorMetadata, org.springframework.roo.model.JavaType annotationType) Parses the governor's metadata for the requested annotation JavaType.

Constructor Detail

AbstractAnnotationValues

protected AbstractAnnotationValues(MemberHoldingTypeDetails memberHoldingTypeDetails,
                                   org.springframework.roo.model.JavaType annotationType)

AbstractAnnotationValues

protected AbstractAnnotationValues(MemberHoldingTypeDetailsMetadataItem<?> governorMetadata,
                                   Class<?> annotationType)

Convenience constructor that takes a Class for the annotation type

Parameters:

governorMetadata - to parse (can be null)

annotationType - the annotation class (required)

AbstractAnnotationValues

protected AbstractAnnotationValues(MemberHoldingTypeDetailsMetadataItem<?> governorMetadata,
                                   org.springframework.roo.model.JavaType annotationType)

Parses the governor's metadata for the requested annotation JavaType. If found, makes the annotation available via the annotationMetadata field. Subclasses will then generally use AutoPopulationUtils.populate(Object, AnnotationMetadata) to complete the configuration of the subclass (we don't invoke AutoPopulationUtils from this constructor because the subclass is likely to have set default values for each field, and these will be overwritten when the control flow returns to the subclass constructor).

If the PhysicalTypeMetadata cannot be parsed or does not internally contain a ClassOrInterfaceTypeDetails, no attempt will be made to populate the values.

Parameters:

governorMetadata - to parse (can be null)

annotationType - to locate and parse (can be null)

Method Detail

getGovernorTypeDetails

public ClassOrInterfaceTypeDetails getGovernorTypeDetails()

Returns:

the type which declared the annotation (ie the governor; never returns null)

isAnnotationFound

public boolean isAnnotationFound()

isClassParsed

public boolean isClassParsed()
