Method Detail

getPropertyDescriptor

public PojoPropertyDescriptorImpl getPropertyDescriptor(String propertyName)

Description copied from interface: PojoDescriptor

This method gets the descriptor for the property identified by the given propertyName.

Parameters:

propertyName - is the name of the requested property.

Returns:

the descriptor for the property identified by the given propertyName or null if no such property exists for the according pojo.

getPropertyDescriptors

public Collection<PojoPropertyDescriptorImpl> getPropertyDescriptors()

This method gets the descriptors of all properties of the according pojo.

Specified by:

getPropertyDescriptors in interface PojoDescriptor<POJO>

Specified by:

getPropertyDescriptors in class AbstractPojoDescriptor<POJO>

Returns:

a collection with all property descriptors

getAccessor

public <ACCESSOR extends PojoPropertyAccessor> ACCESSOR getAccessor(String property,
                                                                    PojoPropertyAccessorMode<ACCESSOR> mode,
                                                                    boolean required)

Description copied from interface: PojoDescriptor

This method gets the accessor for the given mode from the descriptor with the given propertyName .

Type Parameters:

ACCESSOR - is the type of the requested accessor.

Parameters:

property - is the name of the property. If the given mode is GET it is treated as for PojoDescriptor.getProperty(Object, String). If the given mode is SET it is treated as for PojoDescriptor.setProperty(Object, String, Object).

mode - is the mode of the requested accessor. Use PojoPropertyAccessorModes for available modes.

required - - if true the accessor is required and an exception is thrown if NOT found.

Returns:

the requested accessor or null if NOT found and required is false.
