Constructor Detail

PojoPropertyAccessorProxyGetByKey

public PojoPropertyAccessorProxyGetByKey(PojoPropertyAccessorOneArg delegate,
                                         Object key)

The constructor.

Parameters:

delegate - is the delegate.

key - is the mapped key to use.

Method Detail

getMode

public PojoPropertyAccessorNonArgMode getMode()

This method gets the mode of this accessor.

Specified by:

getMode in interface PojoPropertyAccessor

Specified by:

getMode in interface PojoPropertyAccessorNonArg

Overrides:

getMode in class AbstractPojoPropertyAccessorProxy

Returns:

the access mode.

getDelegate

protected PojoPropertyAccessorOneArg getDelegate()

This method gets the accessor this proxy delegates to.

Specified by:

getDelegate in class AbstractPojoPropertyAccessorProxy

Returns:

the delegate.

invoke

public Object invoke(Object pojoInstance)
              throws ReflectionException

This method invokes the according property-method of pojoInstance with the given arguments.

Specified by:

invoke in interface PojoPropertyAccessorNonArg

Parameters:

pojoInstance - is the instance of the POJO where to access the property. Has to be an instance of the type from where this accessor was created for.

Returns:

the result of the invocation. It will be null if void (e.g. initialize method). For a regular getter this will be the value of the property.

Throws:

ReflectionException - if the underlying accessor caused an error during reflection.
