RuntimeVisibleParameterAnnotationsAttribute

public RuntimeVisibleParameterAnnotationsAttribute(ArrayList[] annotations)

Create a new RuntimeVisibleParameterAnnotations attribute for a given array of annotations. Every i-th element of the array is a list of annotations for the i-th parameter. The number of parameters is equal to the length of the array.

Parameters:

annotations - parameter annotations, reference is captured

RuntimeVisibleParameterAnnotationsAttribute

public RuntimeVisibleParameterAnnotationsAttribute(DataInput in,
                                                   ConstantPool cp)
                                            throws IOException,
                                                   ClassFileFormatException

Constructs a RuntimeVisibleParameterAnnotations attribute from a classfile stream.

Parameters:

in - the stream to read from

cp - the constant pool

Throws:

IOException - an IO problem has occured

ClassFileFormatException - the classfile is malformed

getParameterCount

public int getParameterCount()

Get the number of parameters as given in this attribute.

get

public Annotation get(int param,
                      String name)

Return the annotation of a given type for the specified parameter given by its index, or null if no such annotation has been attached to the parameter.

Parameters:

param - the index of the desired parameter

name - the name of the annotation (i.e. the interface type)

getTag

protected int getTag()

Return the attribute's tag.

getSize

protected int getSize()

Return the space in bytes used by this attribute in the classfile.

resolveConstants

protected void resolveConstants(ConstantPool cp)
                         throws ClassFileFormatException

Insert or check location of constant value on constant pool.

Parameters:

cp - the constant pool for this class

Throws:

ClassFileFormatException

write

protected void write(ConstantPool cp,
                     DataOutput out)
              throws IOException

Write this attribute into the file (out) getting data position from the constant pool.

Parameters:

cp - the constant pool that contain all data

out - the file where to write this object info

Throws:

IOException - an io problem has occured
