com.sas.iquery.metadata.expr.relational
Class SimpleConditionalExpression_In

com.sas.iquery.metadata.expr.relational.SimpleConditionalExpression_In

All Implemented Interfaces:

Base, BusinessModelResourceReferencer, CascadableFilter, ModelItem, UsabilityInterface, ExpressionInterface, PropertyChangeListenee, java.beans.PropertyChangeListener, java.lang.Cloneable, java.util.EventListener

public class SimpleConditionalExpression_In
implements BusinessModelResourceReferencer

Models the IN simple conditional expression, which has the following abstract form:
<WhatToCompare> [NOT] IN (<ComparisonList>) .

The IN conditional expression is really a set-membership testing expression. That is, it is used to test whether or not a value is "in" a list of provided values.

Method Detail

setWhatToCompare

public void setWhatToCompare(ExpressionInterface expr)

Sets the expression for what the list of values will be compared to. (<WhatToCompare> [NOT] IN (<ComparisonList>)).

Property change events signaled:

• EVENT_WHAT_TO_COMPARE_CHANGED

The expression being set should not be a compound conditional expression.

Parameters:

expr - left side of the in expression

getWhatToCompare

public ExpressionInterface getWhatToCompare()

Gets the expression being tested by the list of values.

Returns:

the left side of the in expression.

setComparisonList

public void setComparisonList(@Nonnull
                              java.util.List<? extends ExpressionInterface> values)

Sets the list of values to be append after the IN keyword. Each value in the list must be of type ExpressionInterface and cannot be a CompoundConditionalExpression.

Property change events signaled:

• EVENT_COMPARISON_LIST_CHANGED

Parameters:

values - expression interface elements that make up the IN clause

getComparisonList

public java.util.List<ExpressionInterface> getComparisonList()
