java.lang.Objectsbrt.shell.text.math.LinearCombFormatV2<V>
V
- the variable type.public final class LinearCombFormatV2<V>
This class is a concrete implementation of LinearCombFormat. The linear combination format defined by this class looks like:
coefficient1 variable1 + constant
In terms, the
coefficients must appear before the variable, and the two must be separated
by at least one whitespace character. Terms must be separated by +
signs. Coefficients, constants, variables, and +
signs must all be
separated from each other by at least one whitespace character, which means
variable strings cannot contain any whitespace characters. The constant in a
linear combination string can occurr in any sensible position.
