trait Signature_attributeReader extends AttributeReader with ClassFileReaderConfiguration
Implements the template method to read signature attributes.
The Signature attribute is an optional attribute in the attributes table of a ClassFile, field_info or method_info structure.

A DeferredActionsStore stores all functions that need to perform post load actions.
One example is the resolution of references to attributes. (The constant pool is the only structure that is passed around and hence it is the only place where to store information/functions related to a specific class file).

Creates a

Signature_attribute.From the Specification
The constant pool entry at signature_index must be a CONSTANT_Utf8_info structure representing either a class signature, if this signature attribute is an attribute of a ClassFile structure, a method type signature, if this signature is an attribute of a method_info structure, or a field type signature otherwise.

AttributesReaderthat manages the attributes of a class, method_info, field_info or code_attribute structure.- reader
A map where the key is the name of an attribute and the value is a function that given a data input stream that is positioned directly at the beginning of the attribute, the constant pool, the index of the attribute's name and the parent of the attribute reads in the attribute and returns it.

Registers a new processor for the list of all attributes of a given class file structure (class, field_info, method_info, code_attribute). This can be used to post-process attributes. E.g., to merge multiple line number tables if they exist or to remove attributes if they are completely resolved.

This method was primarily introduced because we found many class files with invalid signatures AND the JVM also handles this case gracefully!
