mergePropertyWithReflection

public static final <MERGE_IN,WITH> boolean mergePropertyWithReflection(MERGE_IN mergeInObject,
                                                                        WITH withObject,
                                                                        String fieldName)

Merge the given property to the given 'to' object with the given 'with' object over reflection.

Type Parameters:

MERGE_IN - the generic type of the object to merge in

WITH - the generic type of the object to merge with

Parameters:

mergeInObject - the object to merge in, in other words the target

withObject - the object to merge with, in other words the source

fieldName - the field name

Returns:

true, if successful

Throws:

IllegalArgumentException - if the mergeInObject or withObject argument is null or if the mergeInObject property type is different from the source type and the relevant converter has not been registered.

SecurityException - is thrown if a security manager says no.

merge

public static final <MERGE_IN,WITH> MERGE_IN merge(MERGE_IN mergeInObject,
                                                   WITH withObject)
                                            throws InvocationTargetException,
                                                   IllegalAccessException,
                                                   IllegalArgumentException

Merge the given to object with the given 'with' object.

Type Parameters:

MERGE_IN - the generic type of the object to merge in

WITH - the generic type of the object to merge with

Parameters:

mergeInObject - the object to merge in

withObject - the object to merge with

Returns:

the merged object.

Throws:

InvocationTargetException - if the property accessor method throws an exception

IllegalAccessException - if the caller does not have access to the property accessor method

IllegalArgumentException - if the mergeInObject or withObject argument is null or if the mergeInObject property type is different from the source type and the relevant converter has not been registered.

mergeProperty

public static final <MERGE_IN,WITH> boolean mergeProperty(MERGE_IN mergeInObject,
                                                          WITH withObject,
                                                          PropertyDescriptor propertyDescriptor)
                                                   throws IllegalAccessException,
                                                          InvocationTargetException,
                                                          IllegalArgumentException

Merge the given property to the given 'to' object with the given 'with' object.

Type Parameters:

MERGE_IN - the generic type of the object to merge in

WITH - the generic type of the object to merge with

Parameters:

mergeInObject - the object to merge in

withObject - the object to merge with

propertyDescriptor - the property descriptor

Returns:

true, if merge was successful otherwise false

Throws:

InvocationTargetException - if the property accessor method throws an exception

IllegalAccessException - if the caller does not have access to the property accessor method

IllegalArgumentException - if the mergeInObject or withObject argument is null or if the mergeInObject property type is different from the source type and the relevant converter has not been registered.
