leave

public void leave(ClassFile.CodeAttribute codeAttribute)

Description copied from interface: Java.BlockStatement

Clean up the statement context. This is currently relevant for "try ... catch ... finally" statements (execute "finally" clause) and "synchronized" statements (monitorexit).

Statements like "return", "break", "continue" must call this method for all the statements they terminate.

Notice: The code generated by this method must not modify the operand stack, i.e. if the code needs any state information, then that information must be passed to it in unnamed local variables.

Specified by:

leave in interface Java.BlockStatement
