Class PropertyIsLessThanOrEqualTo

java.lang.Object

com.supermap.services.ogc.filter.Filter

com.supermap.services.ogc.filter.AbstractBinaryExpression

com.supermap.services.ogc.filter.PropertyIsLessThanOrEqualTo

All Implemented Interfaces:

java.io.Serializable

public class PropertyIsLessThanOrEqualTo
extends AbstractBinaryExpression

The abstract class of <PropertyIsLessThanOrEqualTo> elements.

It's a binary comparison operation confining that the value of the first expression is less than or equal to that of the second expression.

A PropertyIsLessThanOrEqualTo element consists of two <expression> child elements, representing the first and the second expression.

Where, the <expression> element is a composite expression of Filter elements. It is an abstract element in OGC and does not actually exist. It represents an expression with a combination of some Filter elements. The Filter elements that can be combined in a <expression> element include: <Add>, <Sub>, <Mul>, <Div>, <PropertyName>, <Literal> , and <Function>.

Constructor Detail

PropertyIsLessThanOrEqualTo

public PropertyIsLessThanOrEqualTo(java.lang.String[] argument)

Constructs a PropertyIsLessThanOrEqualTo object by using the name and the value of the property field.

Represents the condition that the property value is less than or equal to a specified value.

Parameters:

argument - An array of strings. The first element of the array represents the name of the property field, used to construct a PropertyName object. The second element represents the value, used to construct a Literal object.

PropertyIsLessThanOrEqualTo

public PropertyIsLessThanOrEqualTo(Filter firstFilter,
                           Filter secondFilter)

Constructs an object of PropertyIsLessThanOrEqualTo by using two composite expressions.

Represents the condition that the value of the first expression is less than or equal to that of the second expression.

Parameters:

firstFilter - The first composite expression.

secondFilter - The second composite expression.

PropertyIsLessThanOrEqualTo

public PropertyIsLessThanOrEqualTo()
