modifyBean

public R modifyBean(R target)
             throws ModificationException

Description copied from interface: BeanModifier

Modifies the specified bean.

Specified by:

modifyBean in interface BeanModifier<R>

Parameters:

target - the object to modify

Returns:

the modified target (or a modified copy of the target)

Throws:

ModificationException - if modification fails

public static <F,R> R modifyBean(String fieldNameStem,
                                 Method fieldAccessor,
                                 Method fieldMutator,

                                 R target)
                    throws ModificationException

Throws:

ModificationException

protected static <F,R> R modifyBeanInternal(String fieldNameStem,
                                            Method fieldAccessor,

                               throws ModificationException

Throws:

ModificationException

getName

public String getName()

Description copied from interface: NamedInstance

Implementing classes should return a name that will be comparable within some context

Specified by:

getName in interface NamedInstance

Returns:

a value that identifies an instance in some context. This parameter may be null for an anonymous instance, but if it is non-null, the value will be a trimmed String

getContext

public String getContext()

Description copied from interface: NamedInstance

The context in which this instance is named. If another instance has different context from this instance, then implementing classes should ensure that NamedInstance.compareTo(NamedInstance) returns the same (non-zero) value that is the result of comparing the contexts.

Specified by:

getContext in interface NamedInstance

Returns:

may be null if the context is implicit and well understood, and trimmed otherwise

compareContexts

public int compareContexts(NamedInstance namedInstance)

Description copied from interface: NamedInstance

Compares the context of this instance to the context of another instance using the context comparator of this instance.

Specified by:

compareContexts in interface NamedInstance

getContextComparator

public Comparator<String> getContextComparator()

Specified by:

getContextComparator in interface NamedInstance

compareTo

public int compareTo(NamedInstance namedInstance)

Description copied from interface: NamedInstance

Compares this instance to another instance using the comparator of this instance.

Specified by:

compareTo in interface Comparable<NamedInstance>

Specified by:

compareTo in interface NamedInstance

getNamedInstanceComparator

public Comparator<NamedInstance> getNamedInstanceComparator()

Specified by:

getNamedInstanceComparator in interface NamedInstance
