Class ResolveInterceptor

java.lang.Object

jadex.bridge.service.component.interceptors.AbstractApplicableInterceptor

jadex.bridge.service.component.interceptors.ResolveInterceptor

All Implemented Interfaces:

IServiceInvocationInterceptor

public class ResolveInterceptor
extends AbstractApplicableInterceptor

The resolve interceptor is responsible for determining the object on which the method invocation is finally performed. Checks whether the object is a ServiceInfo. In this case it delegates method calls of I(Internal)Service to the automatically created BasicService instance and all other calls to the domain object. // todo: much annotation stuff and injection of objects to the pojo.

Constructor Detail

ResolveInterceptor

public ResolveInterceptor(IInternalAccess ia)

Create a new ResolveInterceptor.

Method Detail

execute

public IFuture<java.lang.Void> execute(ServiceInvocationContext sic)

Execute the interceptor.

Parameters:

context - The invocation context.

invokeDoubleMethod

protected IFuture<java.lang.Void> invokeDoubleMethod(ServiceInvocationContext sic,
                                                     ServiceInfo si,
                                                     java.lang.reflect.Method m,
                                                     java.lang.Class<? extends java.lang.annotation.Annotation> annotation,
                                                     boolean firstorig)

Invoke double methods. The boolean 'firstorig' determines if basicservice method is called first.

findMethod

protected Tuple2<java.lang.reflect.Method,java.lang.Object[]> findMethod(java.lang.Object[] params,
                                                                         ClassInfo[] argtypes,
                                                                         java.lang.Class<?> serclazz,
                                                                         java.lang.String methodname)

Find the correct method by its name and parameter values. The parameter values are half-evaluated, i.e. if they are deserialized as far as possible. Still serialized parameters are saved as SerialiedObject. Those are deserialized using the parameter class as hint.

Parameters:

decparams - Partially decoded parameters.

serclazz - The target class.

methodname - The method name

Returns:

The method and further decoded parameters.

generateParameters

protected java.lang.Object[] generateParameters(java.lang.Object[] vals,
                                                java.lang.reflect.Method m)
                                         throws java.lang.Exception

Generate call parameters.

Parameters:

vals - The current parameters.

Returns:

The adapted method call parameters.

Throws:

java.lang.Exception

convertParameter

protected java.lang.Object convertParameter(java.lang.Object value,
                                            java.lang.reflect.Type targettype)
                                     throws java.lang.Exception

Convert a parameter to a target type.

Throws:

java.lang.Exception

convertToJsonString

protected java.lang.String convertToJsonString(java.lang.Object val)

Convert an object to the json string representation.

Parameters:

val - The value.

Returns:

The string representation.

convertFromJsonString

protected java.lang.Object convertFromJsonString(java.lang.String val,
                                                 java.lang.Class<?> type)

Convert json to object representation.

Parameters:

val - The json value.

Returns:

The object.

convertFromString

protected java.lang.Object convertFromString(java.lang.String val,
                                             java.lang.Class<?> type)

Convert to object representation.

Parameters:

val - The string value.

Returns:

The object.

isSupportedBasicType

protected boolean isSupportedBasicType(java.lang.Class<?> type)

Test if basic converter can handle this type.

Parameters:

type - The type.

Returns:

True if it can handle this type.
