Method Details

getAssembler

protected org.springframework.jmx.export.assembler.MBeanInfoAssembler getAssembler()

setAssembler

public void setAssembler(org.springframework.jmx.export.assembler.MBeanInfoAssembler assembler)

assembler for gathering required MBeanInfo object for a bean

setTemplate

public void setTemplate(Class<? extends ProfilingReportBean> template)

Setter for the ProfilingReportBean instance.

Parameters:

template - the template

setAspectNodeName

public void setAspectNodeName(String aspectNodeName)

Setter of the JMX node name (this node will appear below 'hybris/{Tenant ID}')

Parameters:

aspectNodeName - the JMX node name (default is the class name of the aspect)

setAccuracy

public void setAccuracy(String accuracy)

Setter of the time measure accuracy (use 'ns' for nano seconds , 'ms' for milliseconds [default])

Parameters:

accuracy - the time unit

setDomain

public void setDomain(String domain)

Setter of the JMX domain. Default is JmxUtils.DEFAULT_JMX_DOMAIN

Specified by:

setDomain in interface Profiler

Parameters:

domain - the domain

setLimit

public void setLimit(long limit)

Sets the minimum method execution time. If the execution time of the currently analyzed method is lesser than that value, the method will be ignored.

Specified by:

setLimit in interface Profiler

Parameters:

limit -

getTime

protected long getTime()

Returns the current time in the specified time unit setAccuracy(String)

Returns:

current time

calculateExecutionTime

protected long calculateExecutionTime(long startTime)
