str getDescription ()
 Returns the brief description of this variable, if it has been defined. More...
 
int getFlags ()
 Returns the flags value as set by set_flags(). This includes the trust level and some other settings. See the individual methods is_closed(), get_trust_level(), etc. to pull out the semantic meaning of these flags individually. More...
 
str getName ()
 Returns the name of the variable. More...
 
int getTrustLevel ()
 Returns the minimum trust_level a prc file must demonstrate in order to redefine the value for this variable. Arguably, this should be called the "mistrust level", since the larger the value, the more suspicious we are of prc files. This value is not used if is_closed() returns true, which indicates no file may be trusted. More...
 
ConfigFlags::ValueType getValueType ()
 Returns the stated type of this variable. This should be VT_list, unless a later variable declaration has changed it. More...
 
bool hasLocalValue ()
 Returns true if this variable's value has been shadowed by a local assignment (as created via make_local_value()), or false otherwise. More...
 
bool hasValue ()
 Returns true if this variable has an explicit value, either from a prc file or locally set, or false if variable has its default value. More...
 
bool isClosed ()
 Returns true if the variable is not trusted by any prc file (and hence cannot be modified from its compiled-in default value), or false for the normal case, in which the variable can be modified by any prc file at or above its trust level (see get_trust_level()). More...
 
bool isDynamic ()
 Returns true if the variable was indicated as "dynamic" by its constructor, indicating that its name was dynamically generated, possibly from a large pool, and it should not be listed along with the other variables. More...

Detailed Description

This class is similar to ConfigVariable, but it reports its value as a list of strings. In this special case, all of the declarations of the variable are returned as the elements of this list, in order.

Note that this is different from a normal ConfigVariableString, which just returns its topmost value, which can optionally be treated as a number of discrete words by dividing it at the spaces.

A ConfigVariableList cannot be modified locally.
