time in milliseconds of a parameter with the specified name. Returns null if no parameter exists with the specified name.

getType

public String getType()
A no-op implemenation of the DataConfiguration.getType() method provided so that this class can be instantiated. Not all configuration info supports a getType method; this class is therefore useful as is in these cases.

Specified by:
getType in interface DataConfiguration
Returns:
this no-op method always returns null.

getUniqueStrings

public String[] getUniqueStrings(String paramName)
