Method Detail

getArgumentMatcherIndexes

public static List<Integer> getArgumentMatcherIndexes(ProxyInvocation proxyInvocation,
                                                      int fromLineNr,
                                                      int toLineNr,
                                                      int index)

Locates the argument matchers for the given proxy method invocation.

Parameters:

proxyInvocation - The method invocation, not null

fromLineNr - The begin line-nr of the invocation

toLineNr - The end line-nr of the invocation (could be different from the begin line-nr if the invocation is written on more than 1 line)

index - The index of the matcher on that line, 1 for the first, 2 for the second etc

Returns:

The argument indexes, empty if there are no matchers

getArgumentMatcherIndexes

public static List<Integer> getArgumentMatcherIndexes(Class<?> clazz,
                                                      String methodName,
                                                      Method invokedMethod,
                                                      int fromLineNr,
                                                      int toLineNr,
                                                      int index)

Locates the argument matchers for the method invocation on the given line. An exception is raised when the given method cannot be found.

Parameters:

clazz - The class containing the method invocation, not null

methodName - The method containing the method invocation, not null

invokedMethod - The invocation to look for, not null

fromLineNr - The begin line-nr of the invocation

toLineNr - The end line-nr of the invocation (could be different from the begin line-nr if the invocation is written on more than 1 line)

index - The index of the matcher on that line, 1 for the first, 2 for the second etc

Returns:

The argument indexes, empty if there are no matchers

readClass

protected static org.objectweb.asm.tree.ClassNode readClass(Class<?> clazz)

Uses ASM to read the byte code of the given class. This will access the class file and create some sort of DOM tree for the structure of the bytecode.

Parameters:

clazz - The class to read, not null

Returns:

The structure of the class, not null

findArgumentMatcherIndexes

protected static List<Integer> findArgumentMatcherIndexes(org.objectweb.asm.tree.ClassNode classNode,
                                                          org.objectweb.asm.tree.MethodNode methodNode,
                                                          Class<?> interpretedClass,
                                                          String interpretedMethodName,
                                                          Method invokedMethod,
                                                          int fromLineNr,
                                                          int toLineNr,
                                                          int index)

Locates the argument matchers for the method invocation on the given line.

Parameters:

classNode - The class containing the method invocation, not null

methodNode - The method containing the method invocation, not null

interpretedClass - The current class, not null

interpretedMethodName - The current method name, not null

invokedMethod - The invocation to look for, not null

fromLineNr - The begin line-nr of the invocation

toLineNr - The end line-nr of the invocation (could be different from the begin line-nr if the invocation is written on more than 1 line)

index - The index of the matcher on that line, 1 for the first, 2 for the second etc

Returns:

The argument indexes, null if method was not found, empty if method found but there are no matchers
