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

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.

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.

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

virtual

Virtual destructor.

Member Function Documentation

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.

void te::fe::BinaryComparisonOp::disableMatchCase

(

)

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

void te::fe::BinaryComparisonOp::enableMatchCase

(

)

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

Note

This is the default state.

Expression* te::fe::BinaryComparisonOp::getFirst

(

)

const

It returns the first operand.

Returns

The first operand.

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.

Expression* te::fe::BinaryComparisonOp::getSecond

(

)

const

It returns the second operand.

Returns

The second operand.

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.

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.

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.
