OpenJDK 27 · sun.jvm.hotspot.runtime.SignatureIterator

SignatureIterators iterate over a Java signature (or parts of it). (Syntax according to: "The Java Virtual Machine Specification" by Tim Lindholm & Frank Yellin; section 4.3 Descriptors; p. 89ff.)

Example: Iterating over

([Lfoo;D)I
0123456789

using

iterateParameters() calls: do_array(2, 7); do_double();
iterateReturntype() calls:                              do_int();
iterate()           calls: do_array(2, 7); do_double(); do_int();

is_returnType()        is: false         ; false      ; true
