Constructor Detail

TypeConverter

public TypeConverter(TypeProfileFactory profileFactory)

Creates a type profiler.

Parameters:

profileFactory - the profile factory to use for caching reflection info.

Method Detail

createForType

public <T> T createForType(Object object,

Reflect.creates a new instance of an object for placement in a POJO or elsewhere.

Type Parameters:

T - the return object type.

Parameters:

object - the object to convert to another object

targetType - the target class type to convert to, if the types differ.

Returns:

a suitable object of type targetType.

Throws:

ClassCastException - if the incoming type cannot be converted.

createForType

public <T> T createForType(String memberName,

Type Parameters:

T - the return object type.

Parameters:

memberName - the name of the member that is being converted (for reporting).

object - the object to convert to another object

targetType - the target class type to convert to, if the types differ.

Returns:

a suitable object of type targetType.

Throws:

ClassCastException - if the incoming type cannot be converted.
