Class CognosComplexExpressionBuilder

java.lang.Object

com.ibm.tivoli.maximo.report.cognos.metadata.generator.CognosComplexExpressionBuilder

public class CognosComplexExpressionBuilder
extends java.lang.Object

Cognos Complex Expression Builder is a maxrelationhip parser than converts relationships into cognos complex expressions. This parser supports using groups, and, or, is not, and null, which currently fails when using the Cognos "simple" Relationship Parser. Each object instance of this class should ONLY be used once, and then discarded, since it retains some stateful information about the parsing data. A maximo relationship would look like,

assetnum = :assetnum

and the resulting cognos relationship would look like

[Data Source View].[matusetrans].[assetnum] = [Data Source View].[asset].[assetnum]
