| PropertyUtil | | public class PropertyUtil (Code) | | |
| Method Summary | |
| public static void | copyProperties(Properties src_prop, Properties dest_prop)
Copy a set of properties from one Property to another. | | public static void | loadWithTrimmedValues(InputStream iStr, Properties prop)
Read a set of properties from the received input stream, strip
off any excess white space that exists in those property values,
and then add those newly-read properties to the received
Properties object; not explicitly removing the whitespace here can
lead to problems.
This method exists because of the manner in which the jvm reads
properties from file--extra spaces are ignored after a _key_, but
if they exist at the _end_ of a property decl line (i.e. | | public static String | sortProperties(Properties list)
Sorts a property list and turns the sorted list into a string. | | public static String | sortProperties(Properties list, String indent)
Sorts property list and print out each key=value pair prepended with
specific indentation. |
| copyProperties | | public static void copyProperties(Properties src_prop, Properties dest_prop)(Code) | | Copy a set of properties from one Property to another.
Parameters:
src_prop - Source set of properties to copy from.
Parameters:
dest_prop - Dest Properties to copy into. |
| loadWithTrimmedValues | | public static void loadWithTrimmedValues(InputStream iStr, Properties prop) throws IOException(Code) | | Read a set of properties from the received input stream, strip
off any excess white space that exists in those property values,
and then add those newly-read properties to the received
Properties object; not explicitly removing the whitespace here can
lead to problems.
This method exists because of the manner in which the jvm reads
properties from file--extra spaces are ignored after a _key_, but
if they exist at the _end_ of a property decl line (i.e. as part
of a _value_), they are preserved, as outlined in the Java API:
"Any whitespace after the key is skipped; if the first non-
whitespace character after the key is = or :, then it is ignored
and any whitespace characters after it are also skipped. All
remaining characters on the line become part of the associated
element string."
Parameters:
iStr - An input stream from which the new properties are to beloaded (should already be initialized).
Parameters:
prop - A set of properties to which the properties fromiStr will be added (should already be initialized).properties loaded from 'iStr' (with the extra whitespace (if any)removed from all values), will be returned via the parameter. |
| sortProperties | | public static String sortProperties(Properties list)(Code) | | Sorts a property list and turns the sorted list into a string.
Parameters:
list - property list to sort a string version of the sorted list |
| sortProperties | | public static String sortProperties(Properties list, String indent)(Code) | | Sorts property list and print out each key=value pair prepended with
specific indentation. If indent is null, do not prepend with
indentation.
The output string shows up in two styles, style 1 looks like
{ key1=value1, key2=value2, key3=value3 }
style 2 looks like
key1=value1
key2=value2
key3=value3
where indent goes between the new line and the keys
To get style 1, pass in a null indent
To get sytle 2, pass in non-null indent (whatever you want to go before
the key value)
