Method Detail

getInstance

protected Object getInstance()

Get the wrapped instance

Returns:

the wrapped instance

getReflectedJaloProperty

protected <T> T getReflectedJaloProperty(String methodName,
                                         Class<T> expectedType)

Get the value of a jalo layer item property via reflection. The wrapped instance must be an ItemModel. The source jalo item for the item model is obtained from the model service. The property is looked up on jalo item not the wrapped instance. The getter method must take no arguments and return the expected type.

Type Parameters:

T - The parametrised type for the expected return type

Parameters:

methodName - The name of the property getter method.

expectedType - The type of the property, must match the return type of the getter method.

Returns:

the value of the property

callReflectedMethod

protected <T> T callReflectedMethod(String methodName,
                                    Class<T> expectedType,
                                    Object... params)

Call a method via reflection on the wrapped instance. The method must return the expected type and take parameters of the types specified and in the order specified.

Type Parameters:

T - The parametrised type for the expected return type

Parameters:

methodName - the method name

expectedType - the expected return type

params - the arguments to the method

Returns:

the return value of the method

callReflectedMethod

protected <T> T callReflectedMethod(String methodName,
                                    Class<T> expectedType,
                                    Object[] paramValues,
                                    Class[] paramTypes)

Call a method via reflection on the wrapped instance. The method must return the expected type and take parameters of the types specified and in the order specified.

Type Parameters:

T - The parametrised type for the expected return type

Parameters:

methodName - the method name

expectedType - the expected return type

paramValues - the method parameter values

paramTypes - the method parameter types

Returns:

the return value of the method

modelWrap

protected <T extends ItemModel> T modelWrap(Object item)

Convert a jalo item into its equivalent item model.

Type Parameters:

T - The return type, must extend ItemModel.

Parameters:

item - the item

Returns:

The item model.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

classForName

protected static Class classForName(String className)

Lookup a class for the given class name.

Parameters:

className - the class name

Returns:

the class for the given name, or null if the class cannot be found
