All Implemented Interfaces:

MutablePropertyAccessStrategy, PropertyAccessStrategy

public class ClassPropertyAccessStrategy
extends AbstractPropertyAccessStrategy

An implementation of MutablePropertyAccessStrategy that provides type-save access to data specified by a class. The data is stored in a backing map.

As this class delegates to a MapPropertyAccessor for property access, there is full support for nested properties and collection types.

Constructor Detail

ClassPropertyAccessStrategy

public ClassPropertyAccessStrategy(Class targetClass)

Creates a new instance of ClassPropertyAccessStrategy.

Parameters:

targetClass - the target class

ClassPropertyAccessStrategy

public ClassPropertyAccessStrategy(Object target)

Creates a new instance of ClassPropertyAccessStrategy.

Parameters:

target - the domain object

ClassPropertyAccessStrategy

public ClassPropertyAccessStrategy(ValueModel domainObjectHolder)

Creates a new instance of ClassPropertyAccessStrategy.

Parameters:

domainObjectHolder - the value model containing the domain object

ClassPropertyAccessStrategy

public ClassPropertyAccessStrategy(ValueModel domainObjectHolder,
                                   boolean fieldAccessEnabled)

Creates a new instance of ClassPropertyAccessStrategy.

Parameters:

domainObjectHolder - the value model containing the domain object

fieldAccessEnabled - whether the fields of the objects should be accessed directly where possible instead of using methods

ClassPropertyAccessStrategy

public ClassPropertyAccessStrategy(ValueModel domainObjectHolder,
                                   boolean fieldAccessEnabled,
                                   boolean strictNullValueHandling)

Creates a new instance of ClassPropertyAccessStrategy.

Parameters:

domainObjectHolder - the value model containing the domain object

fieldAccessEnabled - whether the fields of the objects should be accessed directly where possible instead of using methods

strictNullValueHandling - whether a NullValueInNestedPathException should be thrown on nested null-values or null should be returned

ClassPropertyAccessStrategy

public ClassPropertyAccessStrategy(ClassPropertyAccessStrategy parent,
                                   String basePropertyPath)

Creates a child instance of ClassPropertyAccessStrategy that will delegate to its parent for property access.

Parameters:

parent - ClassPropertyAccessStrategy which will be used to provide property access

basePropertyPath - property path that will as a base when accessing the parent ClassPropertyAccessStrategy
