方法概要

所有方法静态方法实例方法具体方法
限定符和类型	方法和说明
`ArtMethod`	`backup()`
`boolean`	`compile()` Force compile the method to avoid interpreter mode.
`void`	`ensureResolved()` the static method is lazy resolved, when not resolved, the entry point is a trampoline of a bridge, we can not hook these entry. this method force the static method to be resolved.
`int`	`getAccessFlags()`
`long`	`getAddress()` get the memory address of the inner constructor/method
`static int`	`getArtMethodSize()` The size of an art::mirror::ArtMethod, we use two rule method to measure the size
`long`	`getEntryPointFromJni()`
`long`	`getEntryPointFromQuickCompiledCode()` The entry point of the quick compiled code.
`java.lang.Object`	`getExecutable()`
`long`	`getFieldOffset()`
`java.lang.String`	`getIdentifier()` get the unique identifier of the constructor/method
`int`	`getModifiers()` get the modifiers of origin method/constructor
`java.lang.String`	`getName()` get the origin method's name
`java.lang.Class<?>[]`	`getParameterTypes()` get the parameter type of origin method/constructor
`static long`	`getQuickToInterpreterBridge()`
`java.lang.Class<?>`	`getReturnType()` get the return type of origin method/constructor
`java.lang.Object`	`invoke(java.lang.Object receiver, java.lang.Object... args)` invoke the origin method
`void`	`makePrivate()` force set the private flag of the method.
`static ArtMethod`	`of(java.lang.reflect.Constructor constructor)`
`static ArtMethod`	`of(java.lang.reflect.Method method)`
`static long`	`searchOffset(long base, long range, int value)` search Offset in memory
`static long`	`searchOffset(long base, long range, long value)`
`void`	`setAccessFlags(int newFlags)`
`void`	`setAccessible(boolean accessible)` make the constructor or method accessible
`void`	`setEntryPointFromJni(long entryPointFromJni)`
`void`	`setEntryPointFromQuickCompiledCode(long pointer_entry_point_from_quick_compiled_code)`
