public class MtmCompoundExpression

extends MtmExpression

An MtmExpression that is made up of two or more MtmExpression objects, which are the subexpressions of the MtmCompoundExpression. This class usually represents a multicolumn level, in which the mapping of a value requires more than one relational column.

For example, suppose a time hierarchy draws values from Year, Quarter, and Month columns. The values of Month do not include a Year component (that is, a value would be JAN, not JAN-99). Therefore, to represent a month, you must specify one value from the Year column and one value from the Month column. In this case, the Month level is represented by an MtmCompoundExpression containing two columns, one for Year and one for Month.

Typically, the concatenation string that brings the two columns together is a double colon (::), so one value of an MtmColumnExpression that represents the Month level from our example might be 1999::JAN.

                                      java.lang.Object context)

Calls the visitMtmCompoundExpression method of the specified MtmObjectVisitor and passes that method this MtmCompoundExpression and the specified context object.

Overrides:

acceptVisitor in class MtmObject

Parameters:

visitor - An MtmObjectVisitor.

context - An Object.

Returns:

The Object returned by the visitMtmCompoundExpression method.

getConcatenationString

public java.lang.String getConcatenationString()

Returns:

A String that is the concatenation string for this MtmCompoundExpression.

getSubExpressions

public java.util.List getSubExpressions()

Gets the list of subexpressions for this MtmCompoundExpression.

Returns:

A List of MtmExpression objects that are the subexpressions for this MtmCompoundExpression.

setConcatenationString

public void setConcatenationString(java.lang.String newConcatenationString)

Specifies the concatenation string for this MtmCompoundExpression.

Parameters:

newConcatenationString - A String that specifies the concatenation string for this MtmCompoundExpression.
