Detailed Description

Functor for CachedESTInfo sorting.

This Functor is used when sorting ESTs based on similarity/distance metric by the sort method defined in this class. This functor sorts methods in ascending order with the smallest values at top.

Constructor & Destructor Documentation

LessCachedESTInfo::LessCachedESTInfo ( const ESTAnalyzer * analyzer ) [inline]

Constructor.

The constructor requires a pointer to the ESTAnalyzer that is being used for analysis. The analyzer is used to compare the metrics for sorting CachedESTInfo objects. This constructor is called in the MSTCache class for sorting cache entries.

Parameters:

[in] analyzer The analyzer to be used for comparing the metric values associated with two CachedESTInfo objects.

Member Function Documentation

LessCachedESTInfo::operator()	(	const CachedESTInfo &	estInfo1,
		const CachedESTInfo &	estInfo2
	)			`[inline]`

operator() for CachedESTInfo.

The following operator provides a convenient mechanism for comparing CachedESTInfo objects for sorting. This operator overrides the default STL operator() by comparing only the metrics of two CachedESTInfo objects (ignoring the EST indexes and any other information). This method uses the metric comparison functionality provided by all EST analyzers.

Parameters:

`[in]`	estInfo1	The first CachedESTInfo object to be used for comparison.
`[in]`	estInfo2	The second CachedESTInfo object to be used for comparison.

Returns:: This method returns true if estInfo1.metric is better than estInfo2.metric. Otherwise it returns false.

LessCachedESTInfo& LessCachedESTInfo::operator= ( const LessCachedESTInfo & src ) [private]

A dummy operator=.

The operator=() is supressed for this class as it has constant members whose value is set when the object is created. These values cannot be changed during the lifetime of this object.

Parameters:

[in] src The source object from where data is to be copied. Currently this value is ignored.
