Constants
KEY_STATSD_ATOM
public static final String KEY_STATSD_ATOM
A key describing the statsd atom into which to place this bundle's other contents. The associated value is an integer.
See also:
Constant Value: "bundlesession-statsd-atom"
Public methods
close
public void close ()
Closes this resource, relinquishing any underlying resources.
This method is invoked automatically on objects managed by the
try
-with-resources statement.
equals
public boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation
on non-null object references:
- It is reflexive: for any non-null reference value
x
,x.equals(x)
should returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
Parameters | |
---|---|
o |
Object : This value may be null . |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getSessionId
public LogSessionId getSessionId ()
Returns | |
---|---|
LogSessionId |
This value cannot be null . |
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. |
reportBundleMetrics
public void reportBundleMetrics (PersistableBundle metrics)
Reports metrics via bundle.
The key KEY_STATSD_ATOM
references an integer value that
indicates the statsd atom for the data in this bundle. Other keys
and their types are defined on a per-atom basis.
Parameters | |
---|---|
metrics |
PersistableBundle : This value cannot be null . |
