Method Detail

replaceProperties

public static String replaceProperties(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.

public static String replaceProperties(String string,
                                       Properties props)

Go through the input string and replace any occurance of ${p} with the props.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 ${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

props - - the source for ${x} property ref values, null means use System.getProperty()
