Method Detail

replaceProperties

public static java.lang.String replaceProperties(java.lang.String string)

Go through the input string and replace any occurance of ${p} with the System.getProperty(p) value. If there is no such property p defined, then the ${p} reference will remain unchanged.

If the property reference is of the form ${p:v} and there is no such property p, then the default value v will be returned.

If the property reference is of the form ${p1,p2} or ${p1,p2:v} then the primary and the secondary properties will be tried in turn, before returning either the unchanged input, or the default value.

The property ${/} is replaced with System.getProperty("file.separator") value and the property ${:} is replaced with System.getProperty("path.separator").

Parameters:

string - - the string with possible ${} references

Returns:

the input string with all property references replaced if any. If there are no valid references the input string will be returned.
