SystemTimeInterruptMonitor
Inheritance: java.lang.Object, com.aspose.cells.AbstractInterruptMonitor
public class SystemTimeInterruptMonitor extends AbstractInterruptMonitor
Simple implementation of AbstractInterruptMonitor by checking and comparing current system time with user specified limit.
Remarks
This implementation is just a simple solution for simple scenarios. It needs to frequently retrieve and check the system time so itself may have a negative impact on performance to some extent.
Example
The following example shows how to monitor the load and save procedure with specified time limit:
SystemTimeInterruptMonitor monitor = new SystemTimeInterruptMonitor(false);
LoadOptions lopts = new LoadOptions();
lopts.setInterruptMonitor(monitor);
monitor.startMonitor(1000); //time limit is 1 second
Workbook wb = new Workbook("Large.xlsx", lopts);
//if the time cost of loading the template file exceeds one second, interruption will be required and exception will be thrown here
//otherwise starts to monitor the save procedure
monitor.startMonitor(1500); //time limit is 1.5 seconds
wb.save("result.xlsx");
Constructors
| Constructor | Description |
|---|---|
| SystemTimeInterruptMonitor(boolean terminateWithoutException) | Constructs one interruption monitor. |
Methods
| Method | Description |
|---|---|
| equals(Object arg0) | |
| getClass() | |
| getTerminateWithoutException() | See AbstractInterruptMonitor.getTerminateWithoutException(). |
| hashCode() | |
| isInterruptionRequested() | This implementation just checks whether the time cost(from the time when starting this monitor to now) is greater than user specified limit. |
| notify() | |
| notifyAll() | |
| startMonitor(int msLimit) | Starts the monitor with the specified time limit. |
| toString() | |

SystemTimeInterruptMonitor(boolean terminateWithoutException)
public SystemTimeInterruptMonitor(boolean terminateWithoutException)
Constructs one interruption monitor.
Parameters:
| Parameter | Type | Description |
|---|---|---|
| terminateWithoutException | boolean | AbstractInterruptMonitor.getTerminateWithoutException() |
equals(Object arg0)
public boolean equals(Object arg0)
Parameters:
| Parameter | Type | Description |
|---|---|---|
| arg0 | java.lang.Object |
Returns: boolean
getClass()
public final native Class<?> getClass()
Returns: java.lang.Class
getTerminateWithoutException()
public boolean getTerminateWithoutException()
See AbstractInterruptMonitor.getTerminateWithoutException(). This property is specified by user when constructing this monitor instance.
Returns: boolean
hashCode()
public native int hashCode()
Returns: int
isInterruptionRequested()
public boolean isInterruptionRequested()
This implementation just checks whether the time cost(from the time when starting this monitor to now) is greater than user specified limit.
Returns: boolean
notify()
public final native void notify()
notifyAll()
public final native void notifyAll()
startMonitor(int msLimit)
public void startMonitor(int msLimit)
Starts the monitor with the specified time limit. The start time to calculate time cost is just when this method is called, so the procedure which needs to be monitored should be started just after this call.
Parameters:
| Parameter | Type | Description |
|---|---|---|
| msLimit | int | time limit(ms) to require the interruption. |
toString()
public String toString()
Returns: java.lang.String
wait()
public final void wait()
wait(long arg0)
public final native void wait(long arg0)
Parameters:
| Parameter | Type | Description |
|---|---|---|
| arg0 | long |
wait(long arg0, int arg1)
public final void wait(long arg0, int arg1)
Parameters:
| Parameter | Type | Description |
|---|---|---|
| arg0 | long | |
| arg1 | int |
