panda3d.core.ConfigVariableBase¶

from panda3d.core import ConfigVariableBase

class ConfigVariableBase

Bases: ConfigFlags

This class is the base class for both ConfigVariableList and ConfigVariable (and hence for all of the ConfigVariableBool, ConfigVaribleString, etc. classes). It collects together the common interface for all generic ConfigVariables.

Mostly, this class serves as a thin wrapper around ConfigVariableCore and/or ConfigDeclaration, more or less duplicating the interface presented there.

Inheritance diagram

clearLocalValue() → bool

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.

property closed

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 getTrustLevel()).

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

Return type

bool

property description

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

Return type

string

property dynamic

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.

Return type

bool

getDescription() → str

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

getFlags() → int

Returns the flags value as set by set_flags(). This includes the trust level and some other settings. See the individual methods isClosed(), getTrustLevel(), etc. to pull out the semantic meaning of these flags individually.

getName() → str

Returns the name of the variable.

getTrustLevel() → int

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 isClosed() 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() → ValueType

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

Return type

ValueType

hasLocalValue() → bool

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

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

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 getTrustLevel()).

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

isDynamic() → bool

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.

property name

Returns the name of the variable.

Return type

string

output(out: ostream) → None
property trust_level

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 isClosed() 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).

Return type

int

property value_type

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

Return type

ValueType

write(out: ostream) → None
