Method Detail

get

public C get(IPropertySource source,
             boolean instantiateAll)

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.

set

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

Unsupported.S

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<C> getType(IPropertySource source)
                 throws UtilsException

Always "String.class"

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericCollectionType

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

Always null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericTypes

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

Always null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericMapKeyType

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

Always null.

Parameters:

source - Source context to introspect.

Throws:

UtilsException

getGenericMapValueType

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

Parameters:

source - Source context to introspect.

Throws:

UtilsException

isReadable

public boolean isReadable(IPropertySource source)
                   throws UtilsException

Always true

Parameters:
