Detailed Description

A class for binary comparison operators.

The Common Catalog Query Language defines a standard set of comparison operators (=, <, >, >=, <=, <>). These comparison operators are encoded using the complex type BinaryComparisonOp. This type definition includes the matchCase attribute which is Boolean type and controls whether string comparisons are case sensitive or not. A true value means that string comparisons are case sensitive. This is the default value. A false value means that string comparisons are case insensitive.
The following operators are defined in the Filter Encoding specification:

PropertyIsEqualTo
PropertyIsPropertyIsNotEqualTo
PropertyIsPropertyIsLessThan
PropertyIsPropertyIsGreaterThan
PropertyIsPropertyIsLessThanOrEqualTo
PropertyIsPropertyIsGreaterThanOrEqualTo

Constructor & Destructor Documentation

◆ BinaryComparisonOp() [1/2]

te::fe::BinaryComparisonOp::BinaryComparisonOp ( const char * opName = 0 )

It initializes a new BinaryComparisonOp.

Parameters

opName The comparison operator name.

Note: The BinaryComparisonOp will not take the ownership of the given name.

◆ BinaryComparisonOp() [2/2]

te::fe::BinaryComparisonOp::BinaryComparisonOp	(	const char *	opName,
		Expression *	f,
		Expression *	s
	)

It initializes a new BinaryComparisonOp.

Parameters

opName	The BinaryComparisonOp operator name.
f	The first expression. The BinaryComparisonOp will take the ownership of the given expression.
s	The second expression. The BinaryComparisonOp will take the ownership of the given expression.

Note: The BinaryComparisonOp will not take the ownership of the given name.

◆ ~BinaryComparisonOp()

virtual te::fe::BinaryComparisonOp::~BinaryComparisonOp ( )

virtual

Virtual destructor.

Member Function Documentation

◆ accept()

virtual ReturnType te::common::BaseVisitable< Visitor , void >::accept ( VisitorType & guest ) const

pure virtualinherited

It call the visit method from the guest object.

Parameters

guest The guest or visitor.

Returns: Any valid value define by the template type R.

◆ clone()

ComparisonOp * te::fe::BinaryComparisonOp::clone ( ) const

virtual

It creates a new copy of this object.

Implements te::fe::AbstractOp.

◆ disableMatchCase()

void te::fe::BinaryComparisonOp::disableMatchCase ( )

It disables the match case flag. So comparisons will not be case sensitive.

◆ enableMatchCase()

void te::fe::BinaryComparisonOp::enableMatchCase ( )

It enables the match case flag. So comparisons will be case sensitive.

Note: This is the default state.

◆ getFirst()

Expression * te::fe::BinaryComparisonOp::getFirst ( ) const

It returns the first operand.

Returns: The first operand.

◆ getName()

const char * te::fe::AbstractOp::getName ( ) const

inlineinherited

It returns the operator name.

Returns: The operator name.

Definition at line 82 of file AbstractOp.h.

◆ getSecond()

Expression * te::fe::BinaryComparisonOp::getSecond ( ) const

It returns the second operand.

Returns: The second operand.

◆ setFirst()

void te::fe::BinaryComparisonOp::setFirst ( Expression * first )

It sets the first operand.

Parameters

first The first operand.

Note: It will take the ownership of the first operand.

◆ setName()

void te::fe::AbstractOp::setName ( const char * opName )

inlineinherited

It sets the operator name.

Parameters

opName The operator name.

Definition at line 89 of file AbstractOp.h.

◆ setSecond()

void te::fe::BinaryComparisonOp::setSecond ( Expression * second )

It sets the second operand.

Parameters

second The second operand.

Note: It will take the ownership of the second operand.
