PrintJob

cancel

void cancel ()

Cancels this print job. You can request cancellation of a queued, started, blocked, or failed print job.

equals

boolean equals (Object obj)

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 return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

getId

PrintJobId getId ()

Gets the unique print job id.

getInfo

PrintJobInfo getInfo ()

Gets the PrintJobInfo that describes this job.

Node:The returned info object is a snapshot of the current print job state. Every call to this method returns a fresh info object that reflects the current print job state.

hashCode

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 in equals 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(Object) method, then calling the hashCode 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(java.lang.Object) method, then calling the hashCode 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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

isBlocked

boolean isBlocked ()

Gets whether this print job is blocked. Such a print job is halted due to an abnormal condition. You can request a cancellation via cancel().

isCancelled

boolean isCancelled ()

Gets whether this print job is cancelled. Such a print job was cancelled as a result of a user request. This is a final state. You cannot restart such a print job.

isCompleted

boolean isCompleted ()

Gets whether this print job is completed. Such a print job is successfully printed. You can neither cancel nor restart such a print job.

isFailed

boolean isFailed ()

Gets whether this print job is failed. Such a print job is not successfully printed due to an error. You can request a restart via restart() or cancel via cancel().

isQueued

boolean isQueued ()

Gets whether this print job is queued. Such a print job is ready to be printed. You can request a cancellation via cancel().

isStarted

boolean isStarted ()

Gets whether this print job is started. Such a print job is being printed. You can request a cancellation via cancel().

restart

void restart ()

Restarts this print job. You can request restart of a failed print job.
