Call (JBoss J2EE API) - JBoss 4.0.1 sp1 j2ee API Documentation 英文版文档


javax.xml.rpc
Interface Call


public interface Call

The javax.xml.rpc.Call interface provides support for the dynamic invocation of a service endpoint. The javax.xml.rpc.Service interface acts as a factory for the creation of Call instances. Once a Call instance is created, various setter and getter methods may be used to configure this Call instance.

Method Detail

removeAllParameters

public void removeAllParameters()
Removes all specified parameters from this Call instance. Note that this method removes only the parameters and not the return type. The setReturnType(null) is used to remove the return type.

Throws:
JAXRPCException - This exception may be thrown If this method is called when the method isParameterAndReturnSpecRequired returns false for this Call's operation.

invokeOneWay

public void invokeOneWay(Object[] inputParams)
Invokes a remote method using the one-way interaction mode. The client thread does not normally block waiting for the completion of the server processing for this remote method invocation. When the protocol in use is SOAP/HTTP, this method should block until an HTTP response code has been received or an error occurs. This method must not throw any remote exceptions. This method may throw a JAXRPCException during the processing of the one-way remote call.

Parameters:
inputParams - Object[]--Parameters for this invocation. This includes only the input params.
Throws:
JAXRPCException - if there is an error in the configuration of the Call object (example: a non-void return type has been incorrectly specified for the one-way call) or if there is any error during the invocation of the one-way remote call

getTargetEndpointAddress

public String getTargetEndpointAddress()
Gets the address of a target service endpoint.

Returns:
Address of the target service endpoint as an URI

removeProperty

public void removeProperty(String name)
Removes a named property.

Parameters:
name - Name of the property
Throws:
JAXRPCException - if an invalid or unsupported property name is passed.

setTargetEndpointAddress

public void setTargetEndpointAddress(String address)
Sets the address of the target service endpoint. This address must correspond to the transport specified in the binding for this Call instance.

Parameters:
address - Address of the target service endpoint; specified as an URI

getPropertyNames

public Iterator getPropertyNames()
Gets the names of configurable properties supported by this Call object.

Returns:
Iterator for the property names

getOutputValues

public List getOutputValues()
Returns a List values for the output parameters of the last invoked operation.

Returns:
java.util.List Values for the output parameters. An empty List is returned if there are no output values.
Throws:
JAXRPCException - If this method is invoked for a one-way operation or is invoked before any invoke method has been called.

getOutputParams

public Map getOutputParams()
Returns a Map of {name, value} for the output parameters of the last invoked operation. The parameter names in the returned Map are of type java.lang.String.

Returns:
Map Output parameters for the last Call.invoke(). Empty Map is returned if there are no output parameters.
Throws:
JAXRPCException - If this method is invoked for a one-way operation or is invoked before any invoke method has been called.

Gets the name of the operation to be invoked using this Call instance.

Returns:
Qualified name of the operation

getPortTypeName

public javax.xml.namespace.QName getPortTypeName()
Gets the qualified name of the port type.

Returns:
Qualified name of the port type

getReturnType

Gets the return type for a specific operation

Returns:
Returns the XML type for the return value

setOperationName

public void setOperationName(javax.xml.namespace.QName operationName)

Parameters:
operationName - Qualified name of the operation
Returns:
Returns true if the Call implementation class requires addParameter and setReturnType to be invoked in the client code for the specified operation. This method returns false otherwise.
Throws:
IllegalArgumentException - If invalid operation name is specified

setReturnType

public void setReturnType(javax.xml.namespace.QName xmlType)
Sets the return type for a specific operation. Invoking setReturnType(null) removes the return type for this Call object.

Parameters:

  • If parameters and return type are incorrectly specified

getProperty

public Object getProperty(String name)
Gets the value of a named property.

Parameters:
name - Name of the property

                         ParameterMode parameterMode)
Adds a parameter type and mode for a specific operation. Note that the client code may not call any addParameter and setReturnType methods before calling the invoke method. In this case, the Call implementation class determines the parameter types by using reflection on parameters, using the WSDL description and configured type mapping registry.

Parameters:
