Methods

public void createBCode(org.extendj.ast.CodeGeneration gen)

The general structure of the basic try-with-resources:


 RESOURCE
 BLOCK
 
 Primary Exception Handler
 Automatic Closing of Resource
 Suppressed Exception Handler
 re-throw primary exception
 Automatic Closing of Resource

Pseudocode for basic try-with-resources:


 0  .resourceBegin
 1  emit RESOURCE
 0  store resource
 0  .resourceEnd
 
 0  .blockBegin
 0  emit BLOCK
 0  .blockEnd
 0  goto outerFinally
 
 1  .resourceException
 1  throw
 
 #if BLOCK is not empty:
 
 1  .catchPrimary
 0  store primary
 
 0  .tryCloseBegin
 1  load resource
 0  ifnull innerFinally
 1  load resource
 0  invoke java.lang.AutoCloseable.close()
 0  .tryCloseEnd
 
 0  goto innerFinally
 
 1  .catchSuppressed
 0  store suppressed
 1  load primary
 2  load suppressed
 0  invoke java.lang.Throwable.addSuppressed(Throwable)
 
 0  .innerFinally
 1  load primary
 1  throw
 
 #endif BLOCK is not empty
 
 0  .outerFinally
 1  load resource
 0  ifnull tryEnd
 1  load resource
 0  invoke java.lang.AutoCloseable.close()
 
 0  .tryEnd
 
 Exception Table:
 resourceBegin .. resourceEnd : resourceException
 blockBegin .. blockEnd : catchPrimary
 tryCloseBegin .. tryCloseEnd : catchSuppressed
