                      IProperty key)

Method Detail

get

public Object get(IPropertySource source,
                  boolean instantiateAll)
           throws UtilsException

Description copied from interface: IProperty

Introspects source to retrieve property value. If a nested property is null, tries if requested to instantiate all hierarchy. If this process fails, an exception is raised. If not requested, returns null.

Parameters:

source - Source context to introspect.

instantiateAll - whether to try or not to instantiate null nested properties values.

Throws:

UtilsException

set

public Object set(IPropertySource target,
                  Object obj,
                  boolean instanciateNested)
           throws UtilsException

Sets the requested value in the Map provided by the "property" field, using the key provided by the "key" field.
Please note that even if the "instanciateNested" flag is false, the ultimate Map will not be considered as a Nested Bean and will be instanciated if null and if possible (i.e. if setter is available).

Parameters:

target - Source context to introspect.

obj - Value to set

instanciateNested - whether to try or not to instantiate null nested properties values.

Returns:

Real set value (after eventual cast)

Throws:

UtilsException

getType

public Class<?> getType(IPropertySource source)
                 throws UtilsException

Description copied from interface: IProperty

Tries to detect if the type of the property, knowing the argument type to use. If impossible, returns null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericCollectionType

public Class<?> getGenericCollectionType(IPropertySource source)
                                  throws UtilsException

Description copied from interface: IProperty

Tries to detect if the generic type of the property if the type is a Collection, knowing the argument type to use. If impossible, returns null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericTypes

public Class<?>[] getGenericTypes(IPropertySource source)
                           throws UtilsException

Description copied from interface: IProperty

Tries to detect if the parameterized types of the property, whatever its type is, knowing the argument type to use. If impossible, returns null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericMapKeyType

public Class<?> getGenericMapKeyType(IPropertySource source)
                              throws UtilsException

Description copied from interface: IProperty

Tries to detect if the generic key type of the property if the type is a Map, knowing the argument type to use. If impossible, returns null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericMapValueType

public Class<?> getGenericMapValueType(IPropertySource source)
                                throws UtilsException

Description copied from interface: IProperty

Tries to detect if the generic value type of the property if the type is a Map, knowing the argument type to use. If impossible, returns null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

isReadable

public boolean isReadable(IPropertySource source)
                   throws UtilsException

Description copied from interface: IProperty

Tries to detect if the property will be able to be read in theory, knowing the argument type to use. Might be based on a real bean or only on a type. When undefined, returns true, so that real case will be detected at runtime.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

isWriteable

public boolean isWriteable(IPropertySource target)
                    throws UtilsException

Description copied from interface: IProperty

Tries to detect if the property will be able to be written in theory, knowing the argument type to use. Might be based on a real bean or only on a type. When undefined, returns true, so that real case will be detected at runtime.

Parameters:

target - Source context to introspect.

Throws:

UtilsException
