static boolean | isTrue(String s)
See if a String represents a "true" boolean value, which consists of:
"yes", "true", "on", or "1", in any case. |

"ghi" => "foo"
"deffoojkl" => "baz"
"abcbazmno" => "garply"
getProperty("ghi") => "foo"
getProperty("def${ghi}jkl") => "baz"
getProperty("abc${def${ghi}jkl}mno") => "garply"
Parameters: props
The table of variables to use when substituting.
expr
The property name, prossibly containing substitutions.
defaultValue
The value to use if the top-level substitution does not
exist. May be null
.
The sequence "\X" is identical to "X", except when "X" is one of:
"ghi" = "foo"
"deffoojkl" = "baz"
"abcbazmno" = "garply"
subst("ghi") = "ghi"
subst("def${ghi}jkl") = "deffoojkl"
subst("def\${ghi}jkl") = "def${ghi}jkl"
subst("abc${def${ghi}jkl}mno") = "abcbazmno"
subst("${abc${def${ghi}jkl}mno}") = "garply"
Parameters: props The table of variables to substitute. If this is a Properties object, then the getProperty() method is used instead of the Dictionary class get() method. str The expression containing the substitutions. Embedded property names, bracketted by "${" and "}" are looked up in the props table and replaced with their value. Nested substitutions are allowed.
Returns: The substituted string. If a variable is not found in the table, the empty string is used.
if noEsc
is true, then
The sequence "\X" is identical to "\X" for all X except X=$.
