public MaskedProperty(Properties propsToMask,
    String mask) 
{
	
		this( propsToMask, mask, null );
}

Provides a view to the provided Properties hiding all keys not starting with some [mask.].

Parameters:

propsToMask - the Properties containing the values.

mask -

 public MaskedProperty(Properties propsToMask,
    String mask,
    Properties propsFallBack) 
{
		if ( propsToMask==null || mask==null ) {
			throw new java.lang.IllegalArgumentException();
		}
		this.masked = propsToMask;
		this.radix = mask + ".";
		this.fallBack = propsFallBack;
}

Provides a view to the provided Properties hiding all keys not starting with some [mask.]. If no value is found then a value is returned from propsFallBack, without masking.

Parameters:

propsToMask -

mask -

propsFallBack -
