                     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.

public JAXRException(Throwable cause)

Constructs a JAXRException object initialized with the given Throwable object.

参数:

cause - the Throwable that caused this Exception

getMessage

public 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.

重写:

getMessage in class Throwable

返回:

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 Throwable getCause()

Returns the Throwable embedded in this JAXRException if there is one. Otherwise, this method returns null.

重写:

getCause in class Throwable

返回:

the embedded Throwable or null if there is none

initCause

public Throwable initCause(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.

重写:

initCause in class Throwable

参数:

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.)

返回:

a reference to this Throwable instance.

抛出异常:

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.
