Method Detail

isCompatible

public boolean isCompatible(DataType source,
                            DataType target,
                            boolean remotable)

Description copied from interface: InterfaceContractMapper

Test if the source data type is compatible with the target data type. The compatibility is defined as follows.

• source's logical type is either the same or subtype of the target's logical type

For example, if the source type is a SDO Customer and the target type is a JAXB Customer and both Customer are generated from the same XSD type.

Specified by:

isCompatible in interface InterfaceContractMapper

Parameters:

source - The source data type

target - The target data type

Returns:

isCompatible

public boolean isCompatible(Operation source,
                            Operation target,
                            boolean remotable)

Description copied from interface: InterfaceContractMapper

Check if source operation is compatible with the target operation

Specified by:

isCompatible in interface InterfaceContractMapper

Parameters:

source - The source operation

target - The target operation

Returns:

true if the source operation is compatible with the target operation

checkCompatibility

public boolean checkCompatibility(InterfaceContract source,
                                  InterfaceContract target,
                                  boolean ignoreCallback,
                                  boolean silent)
                           throws IncompatibleInterfaceContractException

Specified by:

checkCompatibility in interface InterfaceContractMapper

Returns:

Throws:

IncompatibleInterfaceContractException

isCompatible

public boolean isCompatible(Interface source,
                            Interface target)

Specified by:

isCompatible in interface InterfaceContractMapper

Returns:

isCompatible

public boolean isCompatible(InterfaceContract source,
                            InterfaceContract target)

Description copied from interface: InterfaceContractMapper

Check the compatibility of the source and the target interface contracts.

A wire may only connect a source to a target if the target implements an interface that is compatible with the interface required by the source. The source and the target are compatible if:

1. the source interface and the target interface MUST either both be remotable or they are both local
2. the methods on the target interface MUST be the same as or be a superset of the methods in the interface specified on the source
3. compatibility for the individual method is defined as compatibility of the signature, that is method name, input types, and output types MUST BE the same.
4. the order of the input and output types also MUST BE the same.
5. the set of Faults and Exceptions expected by the source MUST BE the same or be a superset of those specified by the service.
6. other specified attributes of the two interfaces MUST match, including Scope and Callback interface

Please note this test is not symmetric: the success of isCompatible(A, B) does NOT imply isCompatible(B, A)

Specified by:

isCompatible in interface InterfaceContractMapper

Parameters:

source - The source interface contract

target - The target interface contract

Returns:

true if the source contract can be supported by the target contract

map

public Operation map(Interface target,
                     Operation source)

Description copied from interface: InterfaceContractMapper

Map the source operation to a compatible operation in the target interface

Specified by:

map in interface InterfaceContractMapper

Parameters:

target - The target interface

source - The source operation

Returns:

A compatible operation
