Method Detail

get

Datatype get(java.lang.String id)

Get Datatype instance by its unique id

Returns:

Datatype instance

Throws:

java.lang.IllegalArgumentException - if no datatype with the given name found

get

@Nullable
<T> Datatype<T> get(java.lang.Class<T> javaClass)

Get Datatype instance by the corresponding Java class. This method tries to find matching supertype too.

Returns:

Datatype instance or null if not found

getNN

<T> Datatype<T> getNN(java.lang.Class<T> javaClass)

Get Datatype instance by the corresponding Java class. This method tries to find matching supertype too.

getId

java.lang.String getId(Datatype datatype)

Returns an ID of the given datatype in the registry.

Throws:

java.lang.IllegalArgumentException - if the datatype is not registered

getIdOrNull

@Nullable
java.lang.String getIdOrNull(Datatype datatype)

Returns an ID of the given datatype in the registry or null if datatype is not registered

getIdByJavaClass

java.lang.String getIdByJavaClass(java.lang.Class<?> javaClass)

Returns an ID of a default datatype handling the given Java class. If there is no default, returns the first appropriate datatype.

Throws:

java.lang.IllegalArgumentException - if no datatypes handle the given Java class

getIds

java.util.Set<java.lang.String> getIds()

Returns:

all registered datatype identifiers.

register

void register(Datatype datatype,
              java.lang.String id,
              boolean defaultForJavaClass)

Register a datatype instance

Parameters:

datatype - datatype instance

id - unique registration id

defaultForJavaClass - true if the datatype should be default for a Java class handled by this datatype
