Method Detail

toStringMillis

public static java.lang.String toStringMillis(long millis)

Return a human-readable representation of a duration in milliseconds, up to days.

Parameters:

millis - length of time in milliseconds

Returns:

string representing the same duration in seconds, minutes, etc.

replaceVariables

public static java.lang.String replaceVariables(java.lang.String str,
                                                java.util.Hashtable<java.lang.Object,java.lang.Object> table)

Replace variables of the form "%variable%" with the value associated with the string "variable" in the provided hash table. To give the "%" character its literal meaning, it needs to be escaped as "%%" (double percent).

Parameters:

str - input string

table - hash table with variable-value pairs

Returns:

string with variables replaced by values

stringMatches

public static boolean stringMatches(java.lang.String str,
                                    char separatorChar,
                                    java.lang.String... stringPatterns)

Returns true if the specified string matches one of the patterns. ! = make sure class name does NOT match this pattern (first character prefix only) ? = one character * = zero or more characters except separatorChar (e.g. '/' for Unix file names or '.' for class names) *** = zero or more characters including separatorChar [abc] = Either a, b or c [a-mA-M] = A letter from the ranges a-m or A-M (inclusive) Foo|Bar = either "Foo" or "Bar" () can be used for grouping: "(Integer|Float)Constant" matches "IntegerConstant" and "FloatConstant". The entire file name has to match the pattern, i.e. the regex characters ^ and $ are implicit.

Parameters:

str - string

separatorChar - the character that ends matches of * but not of *** ('.', '/' or '\\' supported)

stringPatterns - variable argument list of patterns

Returns:

true if the specified string matches one of the patterns

match

public static StringOps.MatchResult match(java.lang.String s,
                                          java.lang.String pattern,
                                          int start)

Return the match result of the regex pattern in the string s, beginning at start.

Parameters:

s - the original string

pattern - the regex

start - the character offset where to start

Returns:

the match result; will have found() returning false if not found

match

public static StringOps.MatchResult match(java.lang.String s,
                                          java.lang.String pattern)

Return the match result of the regex pattern in the string s, beginning at 0.

Parameters:

s - the original string

pattern - the regex

Returns:
