Constructor & Destructor Documentation

ComparisonOperators()

te::fe::ComparisonOperators::ComparisonOperators

(

)

It initializes a new ComparisonOperators.

~ComparisonOperators()

te::fe::ComparisonOperators::~ComparisonOperators

(

)

Destructor.

Member Function Documentation

clearValidOperatorList()

static void te::fe::ComparisonOperators::clearValidOperatorList ( )

static

It clears the valid comparison operator list.

findOperator()

static const char * te::fe::ComparisonOperators::findOperator ( const char *  o )

static

It checks if operator 'o' is a valid operator. It returns a pointer to the found operator or NULL otherwise.

Parameters

o	The operator name we are looking for.

loadValidOperatorList()

static void te::fe::ComparisonOperators::loadValidOperatorList ( )

static

It loads the valid comparison operator list.

operator[]()

const char * te::fe::ComparisonOperators::operator[]

(

size_t

i

)

const

It returns a specified comparison operator.

Parameters

i	The index of desired comparison operator.

Returns

A specified comparison operator.

Note

You must not clear the returned comparison operator.

The method will not check the index range.

push_back()

void te::fe::ComparisonOperators::push_back

(

const char *

c

)

It adds the comparison operator to the supported list of operators.

Parameters

c	The comparison operator to be added to the supported list of operators.
