Examples of AnalyzerAdapter

org.deuce.objectweb.asm.commons.AnalyzerAdapter
A {@link MethodAdapter} that keeps track of stack map frame changes between{@link #visitFrame(int,int,Object[],int,Object[]) visitFrame} calls. Thisadapter must be used with the {@link org.objectweb.asm.ClassReader#EXPAND_FRAMES} option. Each visitXXXinstruction delegates to the next visitor in the chain, if any, and then simulates the effect of this instruction on the stack map frame, represented by {@link #locals} and {@link #stack}. The next visitor in the chain can get the state of the stack map frame before each instruction by reading the value of these fields in its visitXXX methods (this requires a reference to the AnalyzerAdapter that is before it in the chain). @author Eric Bruneton
org.objectweb.asm.commons.AnalyzerAdapter
A {@link MethodAdapter} that keeps track of stack map frame changes between{@link #visitFrame(int,int,Object[],int,Object[]) visitFrame} calls. Thisadapter must be used with the {@link org.objectweb.asm.ClassReader#EXPAND_FRAMES} option. Each visitXinstruction delegates to the next visitor in the chain, if any, and then simulates the effect of this instruction on the stack map frame, represented by {@link #locals} and {@link #stack}. The next visitor in the chain can get the state of the stack map frame before each instruction by reading the value of these fields in its visitX methods (this requires a reference to the AnalyzerAdapter that is before it in the chain). If this adapter is used with a class that does not contain stack map table attributes (i.e., pre Java 6 classes) then this adapter may not be able to compute the stack map frame for each instruction. In this case no exception is thrown but the {@link #locals} and {@link #stack} fields will be null forthese instructions. @author Eric Bruneton
