get
public <T> T get(String name, Class<T> type)
Description copied from interface:ValueMap
Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should returnnull
in this case.
-
get
public <T> T get(String name, T defaultValue)
Description copied from interface:ValueMap
Get a named property and convert it into the given type. This method does not support conversion into a primitive type or an array of a primitive type. It should return the default value in this case.
Implementation hint: In the past it was allowed to call this with a 2nd parameter beingnull
. Therefore all implementations should internally callMap.get(Object)
when the 2nd parameter has valuenull
.- Specified by:
get
in interfaceValueMap
- Type Parameters:
T
- The expected type- Parameters:
name
- The name of the propertydefaultValue
- The default value to use if the named property does not exist or cannot be converted to the requested type. The default value is also used to define the type to convert the value to. Must not benull
. If you want to returnnull
by default rather rely onValueMap.get(String, Class)
.- Returns:
- Return named value converted to type T or the default value if non existing or can't be converted.
