public class OrderedProperties

extends java.util.Properties

implements java.io.Serializable

Properties extension that maintains the comment block that appears before each key,value pair and uses a Vector to maintain keys in order. In JRun23 branch, this class maps a key to a vector of values. In Matrix, this class maps a key to a value. store() method has been changed completely to reflect this design change.

getProperties

public java.util.Properties getProperties(java.lang.String propPattern)

Get the set of properties that match a specified pattern. The match pattern accepts a single '*' char anywhere in the pattern. If the '*' is placed somewhere in the middle of the pattern, then then the subset will contain properties that startWith everything before the '*' and end with everything after the '*'. Sample property patterns:

*.bar	returns the subset of properties that end with '.bar'
bar.*	returns the subset of properties that begin with 'bar.'
foo*bar	returns the subset of properties that begin with 'foo' and end with 'bar'

Parameters:

propPattern - a pattern with 0 or 1 '*' chars.

Returns:

the subset of properties that match the specified pattern. Note that changing the properties in the returned subset will not affect this object.

removeProperties

public void removeProperties(java.lang.String propPattern)

Remove the set of properties that match the specified pattern. See getProperties(String) for more info about the pattern.

Parameters:

propPattern - a pattern with 0 or 1 '*' chars.

setProperties

public void setProperties(java.util.Properties props)

Add set of properties to this object. This method will replace the value of any properties that already existed.
