Pointcuts

Methods and Constructors
`call(Signature)`	every call to any method or constructor matching `Signature` at the call site
`execution(Signature)`	every execution of any method or constructor matching `Signature`
Fields
`get(Signature)`	every reference to any field matching `Signature`
`set(Signature)`	every assignment to any field matching `Signature`. The assigned value can be exposed with an `args` pointcut
Exception Handlers
`handler(TypePattern)`	every exception handler for any `Throwable` type in `TypePattern`. The exception value can be exposed with an `args` pointcut
Advice
`adviceexecution()`	every execution of any piece of advice
Initialization
`staticinitialization(TypePattern)`	every execution of a static initializer for any type in `TypePattern`
`initialization(Signature)`	every initialization of an object when the first constructor called in the type matches `Signature`, encompassing the return from the super constructor call to the return of the first-called constructor
`preinitialization(Signature)`	every pre-initialization of an object when the first constructor called in the type matches `Signature`, encompassing the entry of the first-called constructor to the call to the super constructor
Lexical
`within(TypePattern)`	every join point from code defined in a type in `TypePattern`
`withincode(Signature)`	every join point from code defined in a method or constructor matching `Signature`

Instanceof checks and context exposure
`this(Type or Id)`	every join point when the currently executing object is an instance of `Type` or `Id`'s type
`target(Type or Id)`	every join point when the target executing object is an instance of `Type` or `Id`'s type
`args(Type or Id, ...)`	every join point when the arguments are instances of `Type`s or the types of the `Id`s
Control Flow
`cflow(Pointcut)`	every join point in the control flow of each join point `P` picked out by `Pointcut`, including `P` itself
`cflowbelow(Pointcut)`	every join point below the control flow of each join point `P` picked out by `Pointcut`; does not include `P` itself
Conditional
`if(Expression)`	every join point when the boolean `Expression` is `true`

Combination
`! Pointcut`	every join point not picked out by `Pointcut`
`Pointcut0 && Pointcut1`	each join point picked out by both `Pointcut0` and `Pointcut1`
`Pointcut0 \|\| Pointcut1`	each join point picked out by either `Pointcut0` or `Pointcut1`
`( Pointcut )`	each join point picked out by `Pointcut`
