Field Detail

desc
public String desc
The class descriptor of the annotation class.
-
values
public List<Object> values
The name value pairs of this annotation. Each name value pair is stored as two consecutive elements in the list. The name is aString
, and the value may be aByte
,Boolean
,Character
,Short
,Integer
,Long
,Float
,Double
,String
orType
, or a two elements String array (for enumeration values), anAnnotationNode
, or aList
of values of one of the preceding types. The list may be null if there is no name value pair.

Constructor Detail

AnnotationNode
public AnnotationNode(String descriptor)
Constructs a newAnnotationNode
. Subclasses must not use this constructor. Instead, they must use theAnnotationNode(int, String)
version.- Parameters:
descriptor
- the class descriptor of the annotation class.- Throws:
IllegalStateException
- If a subclass calls this constructor.
-
AnnotationNode
public AnnotationNode(int api, String descriptor)
Constructs a newAnnotationNode
.- Parameters:
api
- the ASM API version implemented by this visitor. Must be one ofOpcodes.ASM4
,Opcodes.ASM5
,Opcodes.ASM6
orOpcodes.ASM7
.descriptor
- the class descriptor of the annotation class.

visit
public void visit(String name, Object value)
Description copied from class:AnnotationVisitor
Visits a primitive value of the annotation.- Overrides:
visit
in classAnnotationVisitor
- Parameters:
name
- the value name.value
- the actual value, whose type must beByte
,Boolean
,Character
,Short
,Integer
,Long
,Float
,Double
,String
orType
ofType.OBJECT
orType.ARRAY
sort. This value can also be an array of byte, boolean, short, char, int, long, float or double values (this is equivalent to usingAnnotationVisitor.visitArray(java.lang.String)
and visiting each array element in turn, but is more convenient).
-
visitEnum
public void visitEnum(String name, String descriptor, String value)
Description copied from class:AnnotationVisitor
Visits an enumeration value of the annotation.- Overrides:
visitEnum
in classAnnotationVisitor
- Parameters:
name
- the value name.descriptor
- the class descriptor of the enumeration class.value
- the actual enumeration value.
-
visitAnnotation
public AnnotationVisitor visitAnnotation(String name, String descriptor)
Description copied from class:AnnotationVisitor
Visits a nested annotation value of the annotation.- Overrides:
visitAnnotation
in classAnnotationVisitor
- Parameters:
name
- the value name.descriptor
- the class descriptor of the nested annotation class.- Returns:
- a visitor to visit the actual nested annotation value, or null if this visitor is not interested in visiting this nested annotation. The nested annotation value must be fully visited before calling other methods on this annotation visitor.
-
visitArray
public AnnotationVisitor visitArray(String name)
Description copied from class:AnnotationVisitor
Visits an array value of the annotation. Note that arrays of primitive types (such as byte, boolean, short, char, int, long, float or double) can be passed as value tovisit
. This is whatClassReader
does.- Overrides:
visitArray
in classAnnotationVisitor
- Parameters:
name
- the value name.- Returns:
- a visitor to visit the actual array value elements, or null if this visitor is not interested in visiting these values. The 'name' parameters passed to the methods of this visitor are ignored. All the array values must be visited before calling other methods on this annotation visitor.
-
visitEnd
public void visitEnd()
Description copied from class:AnnotationVisitor
Visits the end of the annotation.- Overrides:
visitEnd
in classAnnotationVisitor
-
check
public void check(int api)
Checks that this annotation node is compatible with the given ASM API version. This method checks that this node, and all its children recursively, do not contain elements that were introduced in more recent versions of the ASM API than the given version.- Parameters:
api
- an ASM API version. Must be one ofOpcodes.ASM4
,Opcodes.ASM5
,Opcodes.ASM6
orOpcodes.ASM7
.
-
accept
public void accept(AnnotationVisitor annotationVisitor)
Makes the given visitor visit this annotation.- Parameters:
annotationVisitor
- an annotation visitor. Maybe null.
