Method Detail

set

public TimeMetrics set(TimeMetrics metrics)

Description copied from class: SystemMetrics

Sets all fields in this to values from the SystemMetrics object passed in: a _deep_ copy that shouldn't share any values with other metrics objects.

Specified by:

set in class SystemMetrics<TimeMetrics>

Returns:

this

sum

public TimeMetrics sum(@Nullable
                       TimeMetrics b,
                       @Nullable
                       TimeMetrics output)

Description copied from class: SystemMetrics

Add values from the SystemMetrics object passed in and sets them on the output object, if available. Does not modify the original object. For convenience, this function accepts null values and will allocate an output object if none is passed in.

Specified by:

sum in class SystemMetrics<TimeMetrics>

Returns:

output set to (this + b)

diff

public TimeMetrics diff(@Nullable
                        TimeMetrics b,
                        @Nullable
                        TimeMetrics output)

Description copied from class: SystemMetrics

Subtract the object passed in from the current object. Does not modify the original object. For convenience, this function accepts null values and will allocate an output object if none is passed in.

Specified by:

diff in class SystemMetrics<TimeMetrics>

Returns:

output set to (this - b)

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
