package org.objectweb.asm;

Defines the JVM opcodes, access flags and array type codes. This interface
does not define all the JVM opcodes because some opcodes are automatically
handled. For example, the xLOAD and xSTORE opcodes are automatically replaced
by xLOAD_n and xSTORE_n opcodes when possible. The xLOAD_n and xSTORE_n
opcodes are therefore not defined in this interface. Likewise for LDC,
automatically replaced by LDC_W or LDC2_W when necessary, WIDE, GOTO_W and
JSR_W.
