/** A JVM class file.
*
* <p>Generic Java classfiles have one additional attribute for classes,
* methods and fields:
* <pre>
* "Signature" (u4 attr-length, u2 signature-index)
* </pre>
*
* <p>A signature gives the full Java type of a method or field. When
* used as a class attribute, it indicates type parameters, followed
* by supertype, followed by all interfaces.
* <pre>
* methodOrFieldSignature ::= type
* classSignature ::= [ typeparams ] supertype { interfacetype }
* </pre>
* <p>The type syntax in signatures is extended as follows:
* <pre>{@literal
* type ::= ... | classtype | methodtype | typevar
* classtype ::= classsig { '.' classsig }
* classig ::= 'L' name [typeargs] ';'
* methodtype ::= [ typeparams ] '(' { type } ')' type
* typevar ::= 'T' name ';'
* typeargs ::= '<' type { type } '>'
* typeparams ::= '<' typeparam { typeparam } '>'
* typeparam ::= name ':' type
* }</pre>
* <p>This class defines constants used in class files as well
* as routines to convert between internal ``.'' and external ``/''
* separators in class names.
*
* <p><b>This is NOT part of any supported API.
* If you write code that depends on this, you do so at your own risk.
* This code and its internal interfaces are subject to change or
* deletion without notice.</b> */
