toLong

public long toLong(NameEngine nameEngine)
            throws ArithmeticException

Description copied from interface: Numerical

toIrpString

public String toIrpString(int radix)

Description copied from class: IrpObject

Returns a computed IRP (-segment) string representation of current IrpObject. Numerical parameters, but not durations etc, will be printed using the radix in the argument.

Specified by:

Specified by:

toElement in interface XmlExport

Overrides:

toElement in class IrpObject

Returns:

weight

public int weight()

Description copied from class: IrpObject

Returns a (somewhat arbitrary) measure of the complexity of the object. Can be used for determining if a decode is "simpler" than another decode.

Specified by:

weight in class IrpObject

Returns:

non-negative integer.

propertiesMap

public Map<String,Object> propertiesMap(boolean eval,
 GeneralSpec generalSpec,
 NameEngine nameEngine)

Generate a map of the properties in the very object.

Specified by:

propertiesMap in class PrimaryItem

Parameters:

eval - If true, evaluate names.

Returns:

invert

public BitwiseParameter invert(BitwiseParameter rhs,
 RecognizeData nameEngine)

Description copied from class: PrimaryItem

Default implementation, for non-invertible expressions.

Specified by:

invert in interface EquationSolving

Overrides:

invert in class PrimaryItem

Returns:

substituteConstantVariables

public PrimaryItem substituteConstantVariables(Map<String,Long> constantVariables)

Description copied from class: PrimaryItem

Returns a PrimaryItem of the same type with all occurrences of the variables in the dictionary replaced by their values in the dictionary. Does not change the containing object. May return the object itself, or share sub-objects with it.

Specified by:
