Constants in ConfigFlags:

ConfigVariableList
ConfigVariableList::ConfigVariableList(string const &name, string const &description = ((string())), int flags = (0));

Description:

getNumUniqueValues
int ConfigVariableList::get_num_unique_values(void) const;

Description: Returns the number of unique values in the variable.

getNumValues
int ConfigVariableList::get_num_values(void) const;

Description: Returns the number of values in the variable.

getStringValue
string ConfigVariableList::get_string_value(int n) const;

Description: Returns the nth value of the variable.

getUniqueValue
string ConfigVariableList::get_unique_value(int n) const;

Description: Returns the nth unique value of the variable.

operator []
string ConfigVariableList::operator [](int n) const;

Description: Returns the nth unique value of the variable. Note that the indexing operator returns the list of unique values, and so the maximum range is get_num_unique_values().

output
void ConfigVariableList::output(ostream &out) const;

Undocumented function.

size
int ConfigVariableList::size(void) const;

Description: Returns the number of unique values of the variable.

write
void ConfigVariableList::write(ostream &out) const;

Undocumented function.

clearLocalValue
bool ConfigVariableBase::clear_local_value(void);

Description: Removes the local value defined for this variable, and allows its value to be once again retrieved from the .prc files.
Returns true if the value was successfully removed, false if it did not exist in the first place.

getDescription
string const &ConfigVariableBase::get_description(void) const;

Description: Returns the brief description of this variable, if it has been defined.

getFlags
int ConfigVariableBase::get_flags(void) const;

Description: 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.

getName
string const &ConfigVariableBase::get_name(void) const;

Description: Returns the name of the variable.

getTrustLevel
int ConfigVariableBase::get_trust_level(void) const;

Description: 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.
This value only has effect in a release build (specifically, when PRC_RESPECT_TRUST_LEVEL is defined true in Config.pp).

getValueType
ConfigFlags::ValueType ConfigVariableBase::get_value_type(void) const;

Description: Returns the stated type of this variable. This should be VT_list, unless a later variable declaration has changed it.

hasLocalValue
bool ConfigVariableBase::has_local_value(void) const;

Description: Returns true if this variable's value has been shadowed by a local assignment (as created via make_local_value()), or false otherwise.

hasValue
bool ConfigVariableBase::has_value(void) const;

Description: 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.

isClosed
bool ConfigVariableBase::is_closed(void) const;

Description: 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()).
This value only has effect in a release build (specifically, when PRC_RESPECT_TRUST_LEVEL is defined true in Config.pp).

isDynamic
bool ConfigVariableBase::is_dynamic(void) const;

Description: 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.

output
void ConfigVariableBase::output(ostream &out) const;

Description:

write
void ConfigVariableBase::write(ostream &out) const;

Description:
