Method Detail

ListSystemProperties

public static java.lang.String ListSystemProperties()

Retrieves all the system properties into a String

Returns:

A String containing all the system properties, one property per line, with the name and value of each property separated by " = "

printKeys

public static void printKeys(java.util.Hashtable h)

Prints all the keys in a Hashtable to the standard output

Parameters:

h - A Hashtable whose keys are to be output

safeFileName

public static java.lang.String safeFileName(java.lang.String s)

Sanitizes a file name, replacing undesirable characters with the "_" character.

Parameters:

s - The filename to be sanitized

Returns:

The sanitized filename

byteToString

public static java.lang.String byteToString(byte[] b)

Reads a String out of a byte array.

Parameters:

b - An array of bytes to be converted to a String

Returns:

The converted String

stringToStringArray

public static java.lang.String[] stringToStringArray(java.lang.String s,
                                                     java.lang.String delim)

Converts a String to an Array of Strings separated by the given separator. Normally used to break a String into its constituent lines. This method is obsolete now that the String.split method is available.

Parameters:

s - The String to be broken up.

delim - The delimiter around which the String will be broken up

Returns:

An array of Strings

stringToPropHash

public static java.util.Hashtable<java.lang.String,java.lang.String> stringToPropHash(java.lang.String s,
                                                                                      java.lang.String delim)

Converts a String to a property hash. The String is first broken up using the specified delimiter. Then the resulting Strings are broken up into a key and value, with the key being anything to the left of the first '=' character and the value anything that is left over. If no '=' character is present, that String is skipped.

Parameters:

s - The String to be broken up.

delim - The delimiter around which the String will be broken up

Returns:

A Hashtable containing the keys and values specified by the input String

stringToPropMap

public static java.util.Map<java.lang.String,java.lang.String> stringToPropMap(java.lang.String s,
                                                                               java.lang.String delim)

Converts a String to a property Map. The String is first broken up using the specified delimiter. Then the resulting Strings are broken up into a key and value, with the key being anything to the left of the first '=' character and the value anything that is left over. If no '=' character is present, that String is skipped.

Parameters:

s - The String to be broken up.

delim - The delimiter around which the String will be broken up

Returns:

A Map containing the keys and values specified by the input String
