Constructor Detail

MethodSummary

public MethodSummary(java.lang.Class<?> service,
                     java.lang.reflect.Method method,
                     com.codahale.metrics.Timer timer)

Create summary.

Parameters:

service - service type

method - method

timer - method metrics

Method Detail

add

public void add(MethodTrack track)

Used during summary object aggregation.

Parameters:

track - track to append to summary

getService

public java.lang.Class<?> getService()

Returns:

method bean class

getMethod

public java.lang.reflect.Method getMethod()

Returns:

method itself

getTracks

public int getTracks()

Returns:

registered tracks count

getErrors

public int getErrors()

Returns:

failed calls count

getMetrics

public com.codahale.metrics.Snapshot getMetrics()

Returns:

metrics timer snapshot (for reporting)

getMin

public java.lang.String getMin()

Returns:

minimal method call duration (string representation)

getMax

public java.lang.String getMax()

Returns:

maximum method call duration (string representation)

getMedian

public java.lang.String getMedian()

Returns:

median method call duration (string representation)

get75thPercentile

public java.lang.String get75thPercentile()

In test, the first execution would be slow (jvm warm up). This percentile should show more or less correct (hot) method execution time, in case of many executions (useful for "raw performance" checks).

Returns:

duration of 75% method calls (string representation)

get95thPercentile

public java.lang.String get95thPercentile()

Returns:

duration of 95% method calls (string representation)

getInstancesCount

public int getInstancesCount()

Returns:

number of different bean instances used for method calls

toStringMethod

public java.lang.String toStringMethod()

Method used for console reporting. Return type is not included because the method could be identified by arguments only.

Returns:

string representation for method (with argument types, but without return type)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

compareTo

public int compareTo(MethodSummary o)

Specified by:

compareTo in interface java.lang.Comparable<MethodSummary>
