      • loadPropertyFile

        public static java.util.Properties loadPropertyFile​(java.io.File propFile,
                                                            java.util.Properties baseProps)
                                                     throws java.io.IOException
        Reads a property file, resolving all internal variables, using the supplied base properties.

        The properties are resolved iteratively, so if the value of property A refers to property B, then after resolution the value of property B will contain the value of property B.

        Parameters:
        propFile - The property file to load.
        baseProps - Properties containing the initial values to substitute into the properties file.
        Returns:
        Properties object containing the properties in the file with their values fully resolved.
        Throws:
        java.io.IOException - if profile does not exist, or cannot be read.
