Parameters

factor	the factor
constant	the named constant

Returns

the expression

Exceptions

IOException

if the expression cannot be constructed

parseTerm() [2/2]

static Expression com.realtime.crossfire.jxclient.skin.io.ExpressionParser.parseTerm ( @NotNull final String  str ) throws IOException

staticprivate

Parses a term which contains no operators.

Parameters

str	the string

Returns

the integer expression

Exceptions

IOException

if the string cannot be parsed
