Method Detail

loadPropertyFile

public static Properties loadPropertyFile(File propFile,
                                          Properties baseProps)
                                   throws 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:

IOException - if profile does not exist, or cannot be read.

                                   throws IOException

Reads a property file, resolving all internal variables.

Parameters:
