AstNe

public AstNe()

Method Detail

str

public java.lang.String str()

Description copied from class: AstRoot

String representation of this Ast object in the Rapids language. For AstPrimitives this is the name of the function; for AstParameters this is either the name of the variable, or the value of the numeric constant that the parameter represents. For more complicated constructs such as AstExec or AstFunction this method should return those objects as a Rapids string.

Specified by:

str in class AstRoot

op

public double op(double l,
                 double r)

Description copied from class: AstBinOp

Override to express a basic math primitive

Specified by:

op in class AstBinOp

frame_op_scalar

public ValFrame frame_op_scalar(Frame fr,
                                double d)

Description copied from class: AstBinOp

Auto-widen the scalar to every element of the frame

Overrides:

frame_op_scalar in class AstBinOp

categoricalOK

public boolean categoricalOK()

Description copied from class: AstBinOp

Does it make sense to run this operation on a categorical variable ?

Overrides:

categoricalOK in class AstBinOp

Returns:

True if the operation may be applied on a categorical variable, otherwise false.

str_op

public double str_op(BufferedString l,
                     BufferedString r)

Overrides:

str_op in class AstBinOp
