                  DataInput in)
           throws IOException,
                  ClassFileFormatException

Read an annotation structure from a classfile.

Throws:

ClassFileFormatException

Annotation

public Annotation(String typeName)

Create an empty annotation of a given type. We can't use reflection yet, as long as MJ doesn't support Java 5 stuff.

addElement

public void addElement(String name,
                       AnnotElementValue value)

Add an element-value pair to the annotation.

getValue

public AnnotElementValue getValue(String elementName)

Return the value of the given element in the notation, or null if the annotation does not contain such an element.

getName

public String getName()

Return the name of the annotation, i.e. the name of the interface type.

resolveConstants

void resolveConstants(ConstantPool cp)

Insert or check location of constant value on constant pool.

Parameters:

cp - the constant pool for this class

write

void write(ConstantPool cp,
           DataOutput out)
     throws IOException

Write the annotation structure to a classfile.

Throws:

IOException

getSize

int getSize()

Return the size of this annotation structure in bytes.

toString

public String toString()

Return a string representation of this annotation.

Overrides:

toString in class Object
