Package jadex.providedservice.impl.service.interceptors

Class ResolveInterceptor

java.lang.Object

jadex.providedservice.impl.service.interceptors.AbstractApplicableInterceptor

jadex.providedservice.impl.service.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 Details

ResolveInterceptor

public ResolveInterceptor(jadex.core.impl.Component ia)

Create a new ResolveInterceptor.

Method Details

execute

public jadex.future.IFuture<Void> execute(ServiceInvocationContext sic)

Execute the interceptor.

Parameters:

sic - The invocation context.

context - The invocation context.

searchMethod

public static Method searchMethod(Class<?> impl,
 Class<? extends Annotation> annotation)

Search an annotation method.

invokeDoubleMethod

protected jadex.future.IFuture<Void> invokeDoubleMethod(ServiceInvocationContext sic,
 ServiceInfo si,
 Method m,
 Class<? extends Annotation> annotation,
 boolean firstorig,
 boolean ignorenotfound)

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

findMethod

protected jadex.common.Tuple2<Method,Object[]> findMethod(Object[] params,
 jadex.common.ClassInfo[] argtypes,
 Class<?> serclazz,
 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:

serclazz - The target class.

methodname - The method name

decparams - Partially decoded parameters.

Returns:

The method and further decoded parameters.

generateParameters

protected Object[] generateParameters(Object[] vals,
 Method m)
                               throws Exception

Generate call parameters.

Parameters:

vals - The current parameters.

Returns:

The adapted method call parameters.

Throws:

Exception

convertParameter

protected Object convertParameter(Object value,
 Type targettype)
                           throws Exception

Convert a parameter to a target type.

Throws:

Exception

getSerializationServices

public final jadex.serialization.ISerializationServices getSerializationServices()

convertToJsonString

protected String convertToJsonString(Object val)

Convert an object to the json string representation.

Parameters:

val - The value.

Returns:

The string representation.

convertFromJsonString

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

Convert json to object representation.

Parameters:

val - The json value.

Returns:

The object.

convertFromString

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

Convert to object representation.

Parameters:

val - The string value.

Returns:

The object.

isSupportedBasicType

protected boolean isSupportedBasicType(Class<?> type)

Test if basic converter can handle this type.

Parameters:

type - The type.

Returns:

True if it can handle this type.
