Detailed Description

Rule that can be used to filter rows based upon field values.

Synopsis

A TBFilterRule is a single rule that consists of a field, a Comparator, and the rule parameters. A rule consists of one comparator and at least one value. A rule can be negated (i.e., "not equal"), or applied to any field (i.e., any field with a value > 5).

Constructor & Destructor Documentation

casa::TBFilterRule::TBFilterRule	(	casacore::String	field,
		tb::Comparator	comparator,
		TBData *	value,
		TBData *	value2 = NULL,
		bool	isNot = false,
		bool	anyField = false
	)

Constructor that takes the rule parameters.

value should be the value being compared against; value2 can only be NULL if the comparator only takes one argument. isNot should be true for negated rules, false otherwise. anyField should be true if the rule applies to any field, false otherwise. The rule "owns" value and value2 in that, upon deletion, they are deleted as well.

Member Function Documentation

int casa::TBFilterRule::anyFieldPasses ( TBTable *  table, int  row  )

private

Checks all fields in the given row.

If any of the fields pass, the index of the first field to pass is returned; otherwise, -1 is returned.

bool casa::TBFilterRule::equals

(

TBFilterRule *

r

)

Returns true if this rule is equal to the given rule, false otherwise.

bool casa::TBFilterRule::getAnyField

(

)

Returns true if this rule applies to any field, false otherwise.

tb::Comparator casa::TBFilterRule::getComparator

(

)

Returns this rule's comparator.

casacore::String casa::TBFilterRule::getField

(

)

Returns the field this rule applies to, or blank if it applies to any field.

bool casa::TBFilterRule::getIsNot

(

)

Returns true if this rule is negated (i.e., "not equal" rather than "equal"), false otherwise.

TBData* casa::TBFilterRule::getValue

(

)

Returns this rule's value.

TBData* casa::TBFilterRule::getValue2

(

)

Returns this rule's second value, or blank if it doesn't have one.

int casa::TBFilterRule::rowPasses	(	TBTable *	table,
		int	row
	)

Checks the given row in the given table.

If the row passes, the index of the first field to pass is returned; if the row does not pass, -1 is returned.
