input - the input string

Returns:

the input with resolved expressions

Throws:

UnresolvedExpressionException - in case an expression could not be resolved

resolveOrOriginal

public static String resolveOrOriginal(String input)

Attempts to substitute all the found expressions in the input with their corresponding resolved values. If any of the found expressions failed to resolve or if the input does not contain any expression, the input is returned as is.

Parameters:

the input with resolved expressions or the original input in case the input didn't contain any expressions or at least one of the expressions could not be resolved
