Sampler#Sampler(String)

Method Detail

getDefaultOnPattern

public java.lang.String getDefaultOnPattern()

Implementation of inherited abstract method. Returns null since ServerSampler doesn't have one default object name.

Specified by:

getDefaultOnPattern in class Sampler

Returns:

Default Object name filtering pattern for this sampler. If null, we'll consider that the Sampler doesn't have one default object name filter.

newSampleData

protected SampleData newSampleData()

Implementation of inherited abstract method.

Specified by:

newSampleData in class Sampler

Returns:

New sample data.

See Also:

Sampler.newSampleData()

poll

protected SampleData poll(SampleData data)

Implementation of inherited abstract method, will call all pollers of this class.

Specified by:

poll in class Sampler

Parameters:

data - Previous sample.

Returns:

Resulting data.
