Method Detail

registerClassName

default boolean registerClassName(byte platformId,
                                  int typeId,
                                  String clsName,
                                  boolean failIfUnregistered)
                           throws IgniteCheckedException

Method to register typeId->class name mapping in marshaller context cluster-wide. This method guarantees that mapping is delivered to all nodes in cluster and blocks caller thread until then.

Parameters:

platformId - Id of a platform (java, .NET, etc.) to register mapping for.

typeId - Type ID.

clsName - Class name.

failIfUnregistered - If true then throw UnregisteredBinaryTypeException with registration future instead of synchronously awaiting for its completion.

Returns:

True if mapping was registered successfully.

Throws:

IgniteCheckedException - In case of error.

registerClassName

@Deprecated
boolean registerClassName(byte platformId,
                                      int typeId,
                                      String clsName)
                               throws IgniteCheckedException

Deprecated. Use registerClassName(byte, int, java.lang.String, boolean) instead. This particular method will be deleted in future releases.

Same as registerClassName(byte, int, java.lang.String, boolean) but with shortened parameters list.

Parameters:

platformId - ID of a platform (java, .NET, etc.) to register mapping for.

typeId - Type ID.

clsName - Class name.

Returns:

True if mapping was registered successfully.

Throws:

IgniteCheckedException

registerClassNameLocally

boolean registerClassNameLocally(byte platformId,
                                 int typeId,
                                 String clsName)
                          throws IgniteCheckedException

Method to register typeId->class name mapping in marshaller context on local node only. No guarantees that the mapping is presented on other nodes are provided. This method is safe to use if there is another source of mappings like metadata persisted on disk and this source is known to be solid and free of conflicts beforehand.

Parameters:

platformId - Id of a platform (java, .NET, etc.) to register mapping for.

typeId - Type id.

clsName - Class name.

Returns:

True if class mapping was registered successfully.

Throws:

IgniteCheckedException - In case of error.

getClass

Class getClass(int typeId,
               ClassLoader ldr)
        throws ClassNotFoundException,
               IgniteCheckedException

Gets class for provided type ID.

Parameters:

typeId - Type ID.

ldr - Class loader.

Returns:

Class.

Throws:

ClassNotFoundException - If class was not found.

IgniteCheckedException - In case of any other error.

getClassName

String getClassName(byte platformId,
                    int typeId)
             throws ClassNotFoundException,
                    IgniteCheckedException

Gets class name for provided (platformId, typeId) pair.

Parameters:

platformId - id of a platform the class was registered for.

typeId - Type ID.

Returns:

Class name

Throws:

ClassNotFoundException - If class was not found.

IgniteCheckedException - In case of any other error.

isSystemType

boolean isSystemType(String typeName)

Checks whether the given type is a system one - JDK class or Ignite class.

Parameters:

typeName - Type name.

Returns:

true if the type is a system one, false otherwise.

classNameFilter

IgnitePredicate<String> classNameFilter()

Returns class name filter.

Returns:

Class name filter.

jdkMarshaller

JdkMarshaller jdkMarshaller()

Returns:

JDK marshaller instance.
