getInstance

public static final ToDouble getInstance()

Get an instance of a ToDouble object. This avoids multiple calls to the constructor. ToDouble is thread safe.

public final double from(IclTerm t,
                         double def)

Convert a Term to a double primitive. If it cannot be converted, use the given default

Returns:

double: the IclTerm as a double, if possible

from

public final double from(IclTerm t)
                  throws java.lang.UnsupportedOperationException

Convert a Term to a double primitive. If it cannot be converted, throw an UnsupportedOperationException

Returns:

double: the IclTerm as a double, if possible

Throws:

java.lang.UnsupportedOperationException - if the IclTerm cannot be converted
