equals

public boolean equals(Object obj)

Specified by:

equals in class IrpObject

isEmpty

public boolean isEmpty(NameEngine nameEngine)

Specified by:

isEmpty in interface IrStreamItem

toLong

public long toLong(NameEngine nameEngine)
            throws NameUnassignedException

Description copied from interface: Numerical

Produces a numerical result.

Specified by:

toLong in interface Numerical

Parameters:

nameEngine - used to resolve names in expressions.

Returns:

result, long.

Throws:

NameUnassignedException

toBitwiseParameter

public BitwiseParameter toBitwiseParameter(RecognizeData recognizeData)

Specified by:

Throws:

NameUnassignedException

getName

public String getName()

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:

toIrpString in interface IrStreamItem

Specified by:

toIrpString in class IrpObject

Parameters:

radix - Radix for parameters.

Returns:

Formatted string.
