Alias to match BaseData API. Checks whether the link requires a path in order to be created. :return: true if the link requires a path. :rtype: boolean

isReadOnly(self: Sofa.Core.Data) → bool

Return whether this data will be read-only in GUIs. :return: True for read-only

isRequired(self: Sofa.Core.Data) → bool

Check whether a data is flagged as required for the creation of an object. :return: true if it is required.

isSet(self: Sofa.Core.Data) → bool

Check if the value has been modified If this data is linked, the value of this data will be considered as modified (even if the parent’s value has not been modified) :return: True if the data has been modified

read(self: Sofa.Core.Data, arg0: str) → bool

Read the command line, set the value of the data to the given content of the command line. :param str: the content of the command line :type str: string

setName(self: Sofa.Core.Data, arg0: str) → None

Set a new name for the data. :param name: the new name :type name: string

setParent(*args, **kwargs)

Overloaded function.

1. setParent(self: Sofa.Core.Data, arg0: Sofa.Core.Data) -> None

   Set a new parent and a new path for the data. :param parent: the new parent of the data :param path: the new path of the data :type parent: BaseData :type path: string

2. setParent(self: Sofa.Core.Data, arg0: str) -> None

   Set a new parent and a new path for the data. :param parent: the new parent of the data :param path: the new path of the data :type parent: BaseData :type path: string

3. setParent(self: Sofa.Core.Data, arg0: sofapython3::LinkPath) -> None

   Set a new parent and a new path for the data. :param parent: the new parent of the data :param path: the new path of the data :type parent: BaseData :type path: string

setPersistent(self: Sofa.Core.Data, arg0: bool) → None

Alias to match BaseData API. Changes the value of a flag, that should be set to true if link requires a path string in order to be created. :param bool: new value for the flag. :type bool: boolean

setReadOnly(self: Sofa.Core.Data, arg0: bool) → None

Set whether this data is read-only. (True for read-only) :param bool: value of the read-only property :type bool: boolean

toList(self: Sofa.Core.Data) → list

Return a list containing the value of the vector of data.

typeName(self: Sofa.Core.Data) → str

Return the name of the type of the data. :rtype: string

unset(self: Sofa.Core.Data) → None

Reset the isSet flag to false, to indicate that the current value is the default for this data.

updateIfDirty(self: Sofa.Core.Data) → None

Utility method to call update if necessary. This method should be called before reading or writing the value of this node.

writeableArray(*args, **kwargs)
