`Set`	`getCredentials()` Gets the credentials associated with this client.
`RegistryService`	`getRegistryService()` Gets the RegistryService interface associated with the Connection.
`boolean`	`isClosed()` Indicated whether this Connection has been closed or not.
`boolean`	`isSynchronous()` Indicates whether a client uses synchronous communication with JAXR provider or not.
`void`	`setCredentials(Set credentials)` Sets the Credentials associated with this client.
`void`	`setSynchronous(boolean sync)` Sets whether the client uses synchronous communication or not.

方法详细信息

getRegistryService

RegistryService getRegistryService()
                                   throws JAXRException

Gets the RegistryService interface associated with the Connection. If a Connection property (e.g. credentials) is set after the client calls getRegistryService then the newly set Connection property is visible to the RegistryService previously returned by this call.

Capability Level: 0

返回:: the RegistryService associated with this object
抛出异常:: JAXRException - If the JAXR provider encounters an internal error
另请参见:: RegistryService

close

void close()
           throws JAXRException

Closes a Connection when it is no longer needed. Since a provider typically allocates significant resources outside the JVM on behalf of a Connection, clients should close them when they are not needed.

Capability Level: 0

抛出异常:: JAXRException - If the JAXR provider encounters an internal error

isClosed

boolean isClosed()
                 throws JAXRException

Indicated whether this Connection has been closed or not.

Capability Level: 0

返回:: true if Connection is closed; false otherwise
抛出异常:: JAXRException - If the JAXR provider encounters an internal error

isSynchronous

boolean isSynchronous()
                      throws JAXRException

Indicates whether a client uses synchronous communication with JAXR provider or not. A JAXR provider must support both modes of communication. A JAXR client can choose which mode it wants to use.

Capability Level: 0

返回:: true if Connection is synchronous (default); false otherwise
抛出异常:: JAXRException - If the JAXR provider encounters an internal error

setSynchronous

void setSynchronous(boolean sync)
                    throws JAXRException

Sets whether the client uses synchronous communication or not. A JAXR client may dynamically change its communication style preference.

Capability Level: 0

参数:: sync - true if Connection is desired to be synchronous; false otherwise
抛出异常:: JAXRException - If the JAXR provider encounters an internal error

setCredentials

void setCredentials(Set credentials)
                    throws JAXRException

Sets the Credentials associated with this client. The credentials is used to authenticate the client with the JAXR provider. A JAXR client may dynamically change its identity by changing the credentials associated with it.

Capability Level: 0

参数:: credentials - a Collection oj java.lang.Objects which provide identity related information for the caller.
抛出异常:: JAXRException - If the JAXR provider encounters an internal error

getCredentials

Set getCredentials()
                   throws JAXRException

Gets the credentials associated with this client.

Capability Level: 0

返回:: Set of java.lang.Object instances. The Collection may be empty but not null.
抛出异常:: JAXRException - If the JAXR provider encounters an internal error
