Subject: [PATCH] Optimize isValidLocation, getType and getBlockData for
|
|
inlining
|
|
|
|
Hot methods, so reduce # of instructions for the method.
|
|
|
|
Move is valid location test to the BlockPosition class so that it can access local variables.
|
|
|
|
Replace all calls to the new place to the unnecessary forward.
|
|
|
|
Optimize getType and getBlockData to manually inline and optimize the calls
