Constructor Summary

JavassistClassMetaData(javassist.bytecode.ClassFile classFile)

Method Summary

Map<String,Object>	getAnnotationAttributes(String annotationType) Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying class).
Set<String>	getAnnotationTypes() Return the names of all annotation types defined on the underlying class.
String	getClassName() Return the name of the underlying class.
String	getEnclosingClassName() Return the name of the enclosing class of the underlying class, or null if the underlying class is a top-level class.
String[]	getInterfaceNames() Return the name of all interfaces that the underlying class implements, or an empty array if there are none.
Set<String>	getMetaAnnotationTypes(String annotationType) Return the names of all meta-annotation types defined on the given annotation type of the underlying class.
String	getSuperClassName() Return the name of the super class of the underlying class, or null if there is no super class defined.
boolean	hasAnnotation(String annotationType) Determine whether the underlying class has an annotation of the given type defined.
boolean	hasEnclosingClass() Return whether the underlying class has an enclosing class (i.e. the underlying class is an inner/nested class or a local class within a method).
boolean	hasMetaAnnotation(String metaAnnotationType) Determine whether the underlying class has an annotation that is itself annotated with the meta-annotation of the given type.
boolean	hasSuperClass() Return whether the underlying class has a super class.
boolean	isAbstract() Return whether the underlying class is marked as abstract.
boolean	isConcrete() Return whether the underlying class represents a concrete class, i.e. neither an interface nor an abstract class.
boolean	isIndependent() Determine whether the underlying class is independent, i.e. whether it is a top-level class or a nested class (static inner class) that can be constructed independent from an enclosing class.
boolean	isInterface() Return whether the underlying class represents an interface.

Method Detail

getClassName

public String getClassName()

Description copied from interface: ClassMetaData

Return the name of the underlying class.

Specified by:

getClassName in interface ClassMetaData

isInterface

public boolean isInterface()

Description copied from interface: ClassMetaData

Return whether the underlying class represents an interface.

Specified by:

isInterface in interface ClassMetaData

isAbstract

public boolean isAbstract()

Description copied from interface: ClassMetaData

Return whether the underlying class is marked as abstract.

Specified by:

isAbstract in interface ClassMetaData

isConcrete

public boolean isConcrete()

Description copied from interface: ClassMetaData

Return whether the underlying class represents a concrete class, i.e. neither an interface nor an abstract class.

Specified by:

isConcrete in interface ClassMetaData

isIndependent

public boolean isIndependent()

Description copied from interface: ClassMetaData

Determine whether the underlying class is independent, i.e. whether it is a top-level class or a nested class (static inner class) that can be constructed independent from an enclosing class.

Specified by:

isIndependent in interface ClassMetaData

hasEnclosingClass

public boolean hasEnclosingClass()

Description copied from interface: ClassMetaData

Return whether the underlying class has an enclosing class (i.e. the underlying class is an inner/nested class or a local class within a method).

If this method returns false, then the underlying class is a top-level class.

Specified by:

hasEnclosingClass in interface ClassMetaData

getEnclosingClassName

public String getEnclosingClassName()

Description copied from interface: ClassMetaData

Return the name of the enclosing class of the underlying class, or null if the underlying class is a top-level class.

Specified by:

getEnclosingClassName in interface ClassMetaData

hasSuperClass

public boolean hasSuperClass()

Description copied from interface: ClassMetaData

Return whether the underlying class has a super class.

Specified by:

hasSuperClass in interface ClassMetaData

getSuperClassName

public String getSuperClassName()

Description copied from interface: ClassMetaData

Return the name of the super class of the underlying class, or null if there is no super class defined.

Specified by:

getSuperClassName in interface ClassMetaData

getInterfaceNames

public String[] getInterfaceNames()

Description copied from interface: ClassMetaData

Return the name of all interfaces that the underlying class implements, or an empty array if there are none.

Specified by:

getInterfaceNames in interface ClassMetaData

getAnnotationTypes

public Set<String> getAnnotationTypes()

Description copied from interface: ClassMetaData

Return the names of all annotation types defined on the underlying class.

Specified by:

getAnnotationTypes in interface ClassMetaData

Returns:

the annotation type names

hasAnnotation

public boolean hasAnnotation(String annotationType)

Description copied from interface: ClassMetaData

Determine whether the underlying class has an annotation of the given type defined.

Specified by:

hasAnnotation in interface ClassMetaData

Parameters:

annotationType - the annotation type to look for

Returns:

whether a matching annotation is defined

getMetaAnnotationTypes

public Set<String> getMetaAnnotationTypes(String annotationType)

Description copied from interface: ClassMetaData

Return the names of all meta-annotation types defined on the given annotation type of the underlying class.

Specified by:

getMetaAnnotationTypes in interface ClassMetaData

Returns:

the meta-annotation type names

hasMetaAnnotation

public boolean hasMetaAnnotation(String metaAnnotationType)

Description copied from interface: ClassMetaData

Determine whether the underlying class has an annotation that is itself annotated with the meta-annotation of the given type.

Specified by:

hasMetaAnnotation in interface ClassMetaData

Parameters:

metaAnnotationType - the meta-annotation type to look for

Returns:

whether a matching meta-annotation is defined

getAnnotationAttributes

public Map<String,Object> getAnnotationAttributes(String annotationType)

Description copied from interface: ClassMetaData

Retrieve the attributes of the annotation of the given type, if any (i.e. if defined on the underlying class).

Specified by:

getAnnotationAttributes in interface ClassMetaData

Parameters:

annotationType - the annotation type to look for

Returns:

a Map of attributes, with the attribute name as key (e.g. "value") and the defined attribute value as Map value. This return value will be null if no matching annotation is defined.
