ConstructorArgumentValues.ValueHolder
Holder for a constructor argument value, with an optional type
attribute indicating the target type of the actual constructor argument.
|
Constructor and Description |

Deep copy constructor.
|
Modifier and Type | Method and Description |
---|---|
void |
addArgumentValues(ConstructorArgumentValues other)
Copy all given argument values into this object, using separate holder
instances to keep the values independent from the original object.
|
void |
addGenericArgumentValue(ConstructorArgumentValues.ValueHolder newValue)
Add a generic argument value to be matched by type or name (if available).
|
void |
addGenericArgumentValue(Object value)
Add a generic argument value to be matched by type.
|
void |
addGenericArgumentValue(Object value,
String type)
Add a generic argument value to be matched by type.
|
void |
addIndexedArgumentValue(int index,
ConstructorArgumentValues.ValueHolder newValue)
Add an argument value for the given index in the constructor argument list.
|
void |
addIndexedArgumentValue(int index,
Object value)
Add an argument value for the given index in the constructor argument list.
|
void |
addIndexedArgumentValue(int index,
Object value,
String type)
Add an argument value for the given index in the constructor argument list.
|
void |
clear()
Clear this holder, removing all argument values.
|
boolean |
equals(Object other) |
int |
getArgumentCount()
Return the number of argument values held in this instance,
counting both indexed and generic argument values.
|
ConstructorArgumentValues.ValueHolder |
getArgumentValue(int index,
Class<?> requiredType)
Look for an argument value that either corresponds to the given index
in the constructor argument list or generically matches by type.
|
ConstructorArgumentValues.ValueHolder |
getArgumentValue(int index,
Class<?> requiredType,
String requiredName)
Look for an argument value that either corresponds to the given index
in the constructor argument list or generically matches by type.
|
ConstructorArgumentValues.ValueHolder |
getArgumentValue(int index,
Class<?> requiredType,
String requiredName,
Set<ConstructorArgumentValues.ValueHolder> usedValueHolders)
Look for an argument value that either corresponds to the given index
in the constructor argument list or generically matches by type.
|
ConstructorArgumentValues.ValueHolder |
getGenericArgumentValue(Class<?> requiredType)
Look for a generic argument value that matches the given type.
|
ConstructorArgumentValues.ValueHolder |
getGenericArgumentValue(Class<?> requiredType,
String requiredName)
Look for a generic argument value that matches the given type.
|
ConstructorArgumentValues.ValueHolder |
getGenericArgumentValue(Class<?> requiredType,
String requiredName,
Set<ConstructorArgumentValues.ValueHolder> usedValueHolders)
Look for the next generic argument value that matches the given type,
ignoring argument values that have already been used in the current
resolution process.
|
List<ConstructorArgumentValues.ValueHolder> |
getGenericArgumentValues()
Return the list of generic argument values.
|
ConstructorArgumentValues.ValueHolder |
getIndexedArgumentValue(int index,
Class<?> requiredType)
Get argument value for the given index in the constructor argument list.
|
ConstructorArgumentValues.ValueHolder |
getIndexedArgumentValue(int index,
Class<?> requiredType,
String requiredName)
Get argument value for the given index in the constructor argument list.
|
Map<Integer,ConstructorArgumentValues.ValueHolder> |
getIndexedArgumentValues()
Return the map of indexed argument values.
|
int |
hashCode() |
boolean |
hasIndexedArgumentValue(int index)
Check whether an argument value has been registered for the given index.
|
boolean |
isEmpty()
Return if this holder does not contain any argument values,
neither indexed ones nor generic ones.
