ResourceUsageMetrics

public ResourceUsageMetrics()

方法详细资料

getCumulativeCpuUsage

public long getCumulativeCpuUsage()

Get the cumulative CPU usage.

setCumulativeCpuUsage

public void setCumulativeCpuUsage(long usage)

Set the cumulative CPU usage.

getVirtualMemoryUsage

public long getVirtualMemoryUsage()

Get the virtual memory usage.

setVirtualMemoryUsage

public void setVirtualMemoryUsage(long usage)

Set the virtual memory usage.

getPhysicalMemoryUsage

public long getPhysicalMemoryUsage()

Get the physical memory usage.

setPhysicalMemoryUsage

public void setPhysicalMemoryUsage(long usage)

Set the physical memory usage.

getHeapUsage

public long getHeapUsage()

Get the total heap usage.

setHeapUsage

public void setHeapUsage(long usage)

Set the total heap usage.

size

public int size()

Returns the size of the serialized data

readFields

public void readFields(DataInput in)
                throws IOException

从接口复制的说明: Writable

Deserialize the fields of this object from in.

For efficiency, implementations should attempt to re-use storage in the existing object where possible.

指定者:

readFields 在接口中 Writable

参数:

in - DataInput to deseriablize this object from.

抛出:

IOException

write

public void write(DataOutput out)
           throws IOException

从接口复制的说明: Writable

Serialize the fields of this object to out.

指定者:

write 在接口中 Writable

参数:

out - DataOuput to serialize this object into.

抛出:

IOException

deepCompare

public void deepCompare(DeepCompare other,
               TreePath loc)
                 throws DeepInequalityException

指定者:

deepCompare 在接口中 DeepCompare

参数:

other - the other comparand that's being compared to me

loc - the path that got to me. In the root, myLocation is null. To process the scalar foo field of the root we will make a recursive call with a TreePath whose fieldName is "bar" and whose index is -1 and whose parent is null. To process the plural bar field of the root we will make a recursive call with a TreePath whose fieldName is "foo" and whose index is -1 and whose parent is also null.

抛出:

DeepInequalityException
