ExprEval

public ExprEval(int style)

ExprEval

public ExprEval(java.lang.String exprStr,
                int style)

Method Detail

getExprStyle

public int getExprStyle()

setExprStr

public void setExprStr(java.lang.String exprStr)

evaluate

public java.lang.Object evaluate(ExprValueSupplier valSupplier)

evaluate

public java.lang.Object evaluate(ExprValueSupplier valSupplier,
                                 Map adfMap)

Evaluate this script basing it on the given valSupplier object. The adfMap allows custom name interpretation for names not found in the valSupplier or are not reserved names.

evaluateForRow

public java.lang.Object evaluateForRow(Row row)

evaluateForRow

public java.lang.Object evaluateForRow(Row row,
                                       Map attrNameValues)

Evaluate this script basing it on the given row object. Attributes of this row are available as top - level names to be referred in the script, along with the names in the given map - attrNameValues. This map allows custom name interpretation.

getRowVal

public static java.lang.Object getRowVal(Row row,
                                         java.lang.String varName)

setRowVal

public static void setRowVal(Row row,
                             java.lang.String varName,
                             java.lang.Object val)

getParsedExpr

public JIParserNode getParsedExpr()

createRowValueSupplier
