Field Summary

Fields

Modifier and Type	Field and Description
protected static int[]	OPCODE_BLACKLIST List of opcodes which must not appear in a class initialiser, mainly a sanity check so that if any of the specified opcodes are found, we can log it as an error condition and then people can bitch at me to fix it.

Field Detail

OPCODE_BLACKLIST

protected static final int[] OPCODE_BLACKLIST

List of opcodes which must not appear in a class initialiser, mainly a sanity check so that if any of the specified opcodes are found, we can log it as an error condition and then people can bitch at me to fix it. Essentially if it turns out that field initialisers can somehow make use of local variables, then I need to write some code to ensure that said locals are shifted so that they don't interfere with locals in the receiving constructor.
