Field Detail

cause

protected java.lang.Throwable cause
The Throwable that caused this JAXRException to occur. This is used when a JAXRException has a nested Throwable.

Constructor Detail

JAXRException

public JAXRException()
Constructs a JAXRException object with no reason or embedded Throwable.


JAXRException

public JAXRException(java.lang.String reason)
Constructs a JAXRException object with the given String as the reason for the exception being thrown.

Parameters:
reason - a description of what caused the exception

JAXRException

public JAXRException(java.lang.String reason,
                     java.lang.Throwable cause)
Constructs a JAXRException object with the given String as the reason for the exception being thrown and the given Throwable object as an embedded Throwable.

Parameters:
reason - a description of what caused the exception
cause - a Throwable object that is to be embedded in this JAXRException object

JAXRException

public JAXRException(java.lang.Throwable cause)
Constructs a JAXRException object initialized with the given Throwable object.

Parameters:
cause - the Throwable that caused this Exception
Method Detail

getMessage

public java.lang.String getMessage()
Returns the detail message for this JAXRException object.

If there is an embedded Throwable, and if the JAXRException object has no detail message of its own, this method will return the detail message from the embedded Throwable.

Overrides:
getMessage in class java.lang.Throwable
Returns:
the error or warning message for this JAXRException or, if it has none, the message of the embedded Throwable, if there is one

getCause

public java.lang.Throwable getCause()
Returns the Throwable embedded in this JAXRException if there is one. Otherwise, this method returns null.

Overrides:
getCause in class java.lang.Throwable
Returns:
the embedded Throwable or null if there is none

initCause

public java.lang.Throwable initCause(java.lang.Throwable cause)
Initializes the cause of this throwable to the specified value. (The cause is the throwable that caused this throwable to get thrown.)

This method can be called at most once. It is generally called from within the constructor, or immediately after creating the throwable. If this throwable was created with JAXRException(Throwable) or JAXRException(String,Throwable), this method cannot be called even once.

Overrides:
initCause in class java.lang.Throwable
Parameters:
cause - the cause (which is saved for later retrieval by the getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
Returns:
a reference to this Throwable instance.
Throws:
IllegalArgumentException - if cause is this throwable. (A throwable cannot be its own cause.)
IllegalStateException - if this throwable was created with JAXRException(Throwable) or JAXRException(String,Throwable), or this method has already been called on this throwable.

getRequestId

public java.lang.String getRequestId()
Description copied from interface: JAXRResponse
Returns the unique id for the request that generated this response.

Capability Level: 0

Specified by:
getRequestId in interface JAXRResponse
Returns:
the request id

getStatus

public int getStatus()
Description copied from interface: JAXRResponse
Returns the status for this response.

Capability Level: 0

Specified by:
getStatus in interface JAXRResponse
Returns:
the status which is an integer enumerated value
See Also:
JAXRResponse#STATUS_SUCCESS

isAvailable

public boolean isAvailable()
                    throws JAXRException
Returns true if a response is available, false otherwise. This is a polling method and must not block.

Specified by:
isAvailable in interface JAXRResponse
Returns:
true if the response is available; false otherwise
Throws:
JAXRException - If the JAXR provider encounters an internal error
