Method Details
-
getCatches
Gets the list of possibly-caught exceptions. This returnsStdTypeList.EMPTY
if this instruction has no handlers, which can be either if this instruction can't possibly throw or if it merely doesn't handle any of its possible exceptions. To determine whether this instruction can throw, useInsn.canThrow()
.- Specified by:
getCatches
in classInsn
- Returns:
non-null;
the catches list
-
accept
Calls the appropriate method on the given visitor, depending on the class of this instance. Subclasses must override this. -
withAddedCatch
Returns an instance that is just like this one, except that it has a catch list with the given item appended to the end. This method throws an exception if this instance can't possibly throw. To determine whether this instruction can throw, useInsn.canThrow()
.- Specified by:
withAddedCatch
in classInsn
- Parameters:
type
-non-null;
type to append to the catch list- Returns:
non-null;
an appropriately-constructed instance
-
withRegisterOffset
Returns an instance that is just like this one, except that all register references have been offset by the given delta.- Specified by:
withRegisterOffset
in classInsn
- Parameters:
delta
- the amount to offset register references by- Returns:
non-null;
an appropriately-constructed instance
-
withNewRegisters
Returns an instance that is just like this one, except with new result and source registers.- Specified by:
withNewRegisters
in classInsn
- Parameters:
result
-null-ok;
new result registersources
-non-null;
new sources registers- Returns:
non-null;
an appropriately-constructed instance
