                           java.lang.reflect.Method setter)

Method Detail

isTypeCompatible

public static boolean isTypeCompatible(java.lang.reflect.Method getter,
                                       java.lang.reflect.Method setter)

Checks if return type of the specified getter is compatible with the type of the first argument of the specified setter. Types compatible if next conditions are satisfied:

• If setter type is a primitive - then getter type is equal
• If getter type is a primitive - then setter type is the corresponding wrapper or its ancestor
• Setter type is assignable from getter type

Throws:

java.lang.IndexOutOfBoundsException - if specified setter has no arguments

getKey

public ClassPropertyKey getKey()

Specified by:

getKey in interface ClassProperty<Type,TargetType>

getType

public java.lang.Class<Type> getType()

Specified by:

getValue

public Type getValue(TargetType target)
              throws java.lang.Exception

Description copied from interface: ClassProperty

If ClassProperty.isStatic() returns true - specified target is ignored and may be null

Specified by:

getValue in interface ClassProperty<Type,TargetType>

Throws:

java.lang.SecurityException - if property getter cannot be accessed

java.lang.IllegalAccessException - if property getter is inaccessible.

java.lang.IllegalArgumentException - if property getter is an instance method and the specified object argument is not an instance of the class or interface declaring the underlying method (or of a subclass or implementor thereof);

java.lang.reflect.InvocationTargetException - if the underlying method throws an exception.

java.lang.NullPointerException - if the specified object is null and the method is an instance method.

java.lang.ExceptionInInitializerError - if the initialization provoked by this method fails.

java.lang.Exception

Description copied from interface: ClassProperty

If ClassProperty.isStatic() returns true - specified target is ignored and may be null

Specified by:

setValue in interface ClassProperty<Type,TargetType>

Throws:
