Field Detail

access

public int access

The field's access flags (see Opcodes). This field also indicates if the field is synthetic and/or deprecated.

name

public String name

The field's name.

desc

public String desc

The field's descriptor (see Type).

signature

public String signature

The field's signature. May be null.

value

public Object value

The field's initial value. This field, which may be null if the field does not have an initial value, must be an Integer, a Float, a Long, a Double or a String.

visibleAnnotations

public List<AnnotationNode> visibleAnnotations

The runtime visible annotations of this field. This list is a list of AnnotationNode objects. May be null.

invisibleAnnotations

public List<AnnotationNode> invisibleAnnotations

The runtime invisible annotations of this field. This list is a list of AnnotationNode objects. May be null.

visibleTypeAnnotations

public List<TypeAnnotationNode> visibleTypeAnnotations

The runtime visible type annotations of this field. This list is a list of TypeAnnotationNode objects. May be null.

invisibleTypeAnnotations

public List<TypeAnnotationNode> invisibleTypeAnnotations

The runtime invisible type annotations of this field. This list is a list of TypeAnnotationNode objects. May be null.

attrs

public List<Attribute> attrs

The non standard attributes of this field. This list is a list of Attribute objects. May be null.

Constructor Detail

FieldNode

public FieldNode(int access,
                 String name,
                 String desc,
                 String signature,
                 Object value)

Constructs a new FieldNode. Subclasses must not use this constructor. Instead, they must use the FieldNode(int, int, String, String, String, Object) version.

Parameters:

access - the field's access flags (see Opcodes). This parameter also indicates if the field is synthetic and/or deprecated.

name - the field's name.

desc - the field's descriptor (see Type).

signature - the field's signature.

value - the field's initial value. This parameter, which may be null if the field does not have an initial value, must be an Integer, a Float, a Long, a Double or a String.

Throws:

IllegalStateException - If a subclass calls this constructor.

FieldNode

public FieldNode(int api,
                 int access,
                 String name,
                 String desc,
                 String signature,
                 Object value)

Constructs a new FieldNode. Subclasses must not use this constructor.

Parameters:

api - the ASM API version implemented by this visitor. Must be one of Opcodes.ASM4 or Opcodes.ASM5.

access - the field's access flags (see Opcodes). This parameter also indicates if the field is synthetic and/or deprecated.

name - the field's name.

desc - the field's descriptor (see Type).

signature - the field's signature.

value - the field's initial value. This parameter, which may be null if the field does not have an initial value, must be an Integer, a Float, a Long, a Double or a String.

Method Detail

visitAnnotation

public AnnotationVisitor visitAnnotation(String desc,
                                         boolean visible)

Description copied from class: FieldVisitor

Visits an annotation of the field.

Overrides:

visitAnnotation in class FieldVisitor

Parameters:

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitTypeAnnotation

public AnnotationVisitor visitTypeAnnotation(int typeRef,
                                             TypePath typePath,
                                             String desc,
                                             boolean visible)

Description copied from class: FieldVisitor

Visits an annotation on the type of the field.

Overrides:

visitTypeAnnotation in class FieldVisitor

Parameters:

typeRef - a reference to the annotated type. The sort of this type reference must be FIELD. See TypeReference.

typePath - the path to the annotated type argument, wildcard bound, array element type, or static inner type within 'typeRef'. May be null if the annotation targets 'typeRef' as a whole.

desc - the class descriptor of the annotation class.

visible - true if the annotation is visible at runtime.

Returns:

a visitor to visit the annotation values, or null if this visitor is not interested in visiting this annotation.

visitAttribute

public void visitAttribute(Attribute attr)

Description copied from class: FieldVisitor

Visits a non standard attribute of the field.

Overrides:

visitAttribute in class FieldVisitor

Parameters:

attr - an attribute.

visitEnd

public void visitEnd()

Description copied from class: FieldVisitor

Visits the end of the field. This method, which is the last one to be called, is used to inform the visitor that all the annotations and attributes of the field have been visited.

Overrides:

visitEnd in class FieldVisitor

check

public void check(int api)

Checks that this field node is compatible with the given ASM API version. This methods checks that this node, and all its nodes 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 of Opcodes.ASM4 or Opcodes.ASM5.

accept

public void accept(ClassVisitor cv)

Makes the given class visitor visit this field.

Parameters:

cv - a class visitor.
