name in interface MetaProperty<B,P>

Returns:

the name of the property, never null

propertyClass

public Class<P> propertyClass()

Description copied from interface: MetaProperty

readWrite in interface MetaProperty<B,P>

Returns:

the property read-write type, never null

get

public P get(B bean)

Gets the value of the bound property for the provided bean.

This is the equivalent to calling getFoo() on the bean itself. However some implementations of this interface may not require an actual get method.

set

public void set(B bean,
                P value)

Specified by:

set in interface MetaProperty<B,P>

Parameters:

bean - the bean to update, not null

value - the value to set into the property on the bound bean
