Method Detail

loadPropertyFile

public static java.util.Properties loadPropertyFile(java.io.File propfile)

Reads a property file, resolving all internal variables.

Parameters:

propfile - The property file to load

Returns:

the loaded and fully resolved Properties object

getInterpolatedPropertyValue

public static java.lang.String getInterpolatedPropertyValue(java.lang.String key,
                                                            java.util.Properties props)

Retrieves a property value, replacing values like ${token} using the Properties to look them up.

It will leave unresolved properties alone, trying for System properties, and implements reparsing (in the case that the value of a property contains a key), and will not loop endlessly on a pair like test = ${test}.

Parameters:

key - The key for which to find the corresponding value

props - The properties from which to find the value.

Returns:

The (possible interpolated) property value
