ConstantPoolSharingOption
is a preview API of the Java platform.
Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
Option describing whether to preserve the original constant pool when
transforming a classfile. Reusing the constant pool enables significant
optimizations in processing time and minimizes differences between the
original and transformed classfile, but may result in a bigger classfile
when a classfile is significantly transformed.
Default is
SHARED_POOL
to preserve the original constant
pool.- Since:
