Public methods
fillInStackTrace
public Throwable fillInStackTrace ()
Fills in the execution stack trace. This method records within this
Throwable
object information about the current state of
the stack frames for the current thread.
If the stack trace of this Throwable
writable, calling this method has no effect.
Returns | |
---|---|
Throwable |
a reference to this Throwable instance. |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap
.
The general contract of hashCode
is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals
method, then calling thehashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns | |
---|---|
int |
a hash code value for this object. |
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 Throwable(java.lang.Throwable)
or
Throwable(java.lang.String, java.lang.Throwable)
, this method cannot be called
even once.
An example of using this method on a legacy throwable type without other support for setting the cause is:
try { lowLevelOp(); } catch (LowLevelException le) { throw (HighLevelException) new HighLevelException().initCause(le); // Legacy constructor }
Parameters | |
---|---|
cause |
Throwable : the cause (which is saved for later retrieval by the
Throwable.getCause() method). (A null value is
permitted, and indicates that the cause is nonexistent or
unknown.) |
Returns | |
---|---|
Throwable |
a reference to this Throwable instance. |
setStackTrace
public void setStackTrace (StackTraceElement[] stackTrace)
Sets the stack trace elements that will be returned by
getStackTrace()
and printed by printStackTrace()
and related methods.
This method, which is designed for use by RPC frameworks and other
advanced systems, allows the client to override the default
stack trace that is either generated by fillInStackTrace()
when a throwable is constructed or deserialized when a throwable is
read from a serialization stream.
If the stack trace of this Throwable
writable, calling this method has no effect other than
validating its argument.
Parameters | |
---|---|
stackTrace |
StackTraceElement : the stack trace elements to be associated with
this Throwable . The specified array is copied by this
call; changes in the specified array after the method invocation
returns will have no affect on this Throwable 's stack
trace. |
