These filter expressions are used to create the rules that define how the Container Filtering Module configured within the Transformer will determine which records in a particular RTTP container match the specified the criteria and should be returned, and which do not.

Example of FieldFilterExpression:

var oFilter = new caplin.grid.filter.FieldFilterExpression("Bid", caplin.grid.filter.FieldFilterExpression.Operator.GREATER_THAN, "100");

Example of LogicalFilterExpression:

var oFilter = new caplin.grid.filter.LogicalFilterExpression(caplin.grid.filter.LogicalFilterExpression.Operator.AND);
oFilter.addFilterExpression(new caplin.grid.filter.FieldFilterExpression("Bid", caplin.grid.filter.FieldFilterExpression.Operator.GREATER_THAN, "100"));
oFilter.addFilterExpression(new caplin.grid.filter.FieldFilterExpression("Bid", caplin.grid.filter.FieldFilterExpression.Operator.LESS_THAN, "102"));

Example of compound LogicalFilterExpression:

var oFilter = new caplin.grid.filter.LogicalFilterExpression(caplin.grid.filter.LogicalFilterExpression.Operator.OR);

var oSubFilter1 = new caplin.grid.filter.LogicalFilterExpression(caplin.grid.filter.LogicalFilterExpression.Operator.AND);
oSubFilter1.addFilterExpression(new caplin.grid.filter.FieldFilterExpression("Bid", caplin.grid.filter.FieldFilterExpression.Operator.GREATER_THAN, "100"));
oSubFilter1.addFilterExpression(new caplin.grid.filter.FieldFilterExpression("Bid", caplin.grid.filter.FieldFilterExpression.Operator.LESS_THAN, "102"));

var oSubFilter2 = new caplin.grid.filter.LogicalFilterExpression(caplin.grid.filter.LogicalFilterExpression.Operator.AND);
oSubFilter2.addFilterExpression(new caplin.grid.filter.FieldFilterExpression("BidYield", caplin.grid.filter.FieldFilterExpression.Operator.GREATER_THAN, "5.5"));
oSubFilter2.addFilterExpression(new caplin.grid.filter.FieldFilterExpression("BidYield", caplin.grid.filter.FieldFilterExpression.Operator.LESS_THAN, "8.5"));

oFilter.addFilterExpression(oSubFilter1);
oFilter.addFilterExpression(oSubFilter2);
