A convenience class to convert property values to specific types.
Perform variable substitution in string val
from the values of keys found in the system propeties.
The variable substitution delimeters are ${ and }.
For example, if the System properties contains "key=value", then the call
A convenience class to convert property values to specific types.
Definition optionconverter.h:47
std::shared_ptr< Ret > cast(const std::shared_ptr< Type > &incoming)
Attempt to cast one Object to another kind of Object.
Definition object.h:126
will set the variable s
to "Value of key is value.".
If no value could be found for the specified key, then the props
parameter is searched, if the value could not be found there, then substitution defaults to the empty string.
For example, if system propeties contains no value for the key "inexistentKey", then the call
auto s =
OptionConverter.subsVars(
"Value of inexistentKey is [${inexistentKey}]");
will set s
to "Value of inexistentKey is []"
An IllegalArgumentException is thrown if val
contains a start delimeter "${" which is not balanced by a stop delimeter "}".
- Parameters
-
val | The string on which variable substitution is performed. |
props | The properties from which variable substitution is performed. |
