public class BusinessQueryDataBasedFilter

A step that filters a query based on a boolean expression.

The left side of the expression is a set of members determining the context on which to evaluate the expression (for example USA, 1999, Sales). The right side of the expression is a data value.

The result of a data based filter is the set of members meeting the criteria set forth in the specified expression.

StepFilterInterface, BaseFilter

Constructor Detail

BusinessQueryDataBasedFilter

public BusinessQueryDataBasedFilter(@NonNull
                                    java.util.List<? extends ExpressionInterface> memberNames,
                                    @NonNull
                                    ComparisonOperator operator,
                                    @NonNull
                                    java.lang.Object value)

Set a filter based on the data values in a set

Parameters:

memberNames - name of values to be checked

operator - used to compare

value - check for

Throws:

java.lang.IllegalArgumentException - if input parameters are null

Method Detail

getMemberLocale

public java.util.Locale getMemberLocale()

Get the locale that is associated with the member names for this step.

Returns:

getDisplayedText

public java.lang.String getDisplayedText(com.sas.storage.olap.MetadataInterface metadata,
                                         Role role,
                                         boolean applyPromptValues,
                                         java.util.Locale locale)

Return the displayed text for a step rather than a OLAP type of text.

Parameters:

metadata -

dataItem -

apply - prompt value (true) or prompt labels.

locale - to use

Returns:

setLeftExpression

public void setLeftExpression(@NonNull
                              java.util.List<? extends ExpressionInterface> values,
                              java.util.Locale locale)

Sets the left expression portion of the conditional expression. This is commonly a list of StringExpression representing member names or data items (with structure of Measure).

Parameters:

values - left side of conditional expression

setLeftExpression

public void setLeftExpression(@NonNull
                              java.util.List<? extends ExpressionInterface> values)

Sets the left expression portion of the conditional expression. This is commonly a list of StringExpression representing member names or data items (with structure of Measure).

Parameters:

values - left side of conditional expression

getLeftExpression

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

Gets the left expression for this conditional expression. This is commonly a list of StringExpressions representing member names or data items (with structure of Measure).

Returns:

the left side expression.

setOperator

public void setOperator(ComparisonOperator operator)

This method defines the type of operator to use for filtering.

Parameters:

operator - The type of operator to be used for filtering

getOperator

public ComparisonOperator getOperator()

This method returns the operator to be used for filtering.

Returns:

The operator to be used for filtering

setRightExpression

public void setRightExpression(java.util.List<? extends NonCalculatedValue> values)

Sets the right expression portion of the conditional expression. This is commonly a single ConstantExpression representing a constant value to be used in the expression, but could also be a more general expression or a list of StringExpressions representing member names.

Parameters:

values - right side of conditional expression

getRightExpression

public java.util.List<NonCalculatedValue> getRightExpression()

Gets the right expression for this conditional expression. This is commonly a single ConstantExpression representing a constant value to be used in the expression, but could also be a more general expression or a list of StringExpressions representing member names.

Returns:

the right side expression.
