Inherited from Dock (via TIEntry):

Method load Loads data into an instance by delegating to Loader methods based on the input's type
Class Variable loaders Undocumented
def __format__(self, format_spec: str) -> str: (source)
overrides tivars.var.TIEntry.__format__

Formats this entry for string representations

Parameters
format_spec:strThe format parameters
Returns
strA string representation of this entry
def __init__(self, init=None, *, for_flash: bool = True, name: str = '[A]', version: int = None, archived: bool = None, data: bytes = None): (source)
overrides tivars.var.TIEntry.__init__

Creates an empty entry with specified meta and data values

The entry version and archived flag are invalid if for_flash == False.

Parameters
initValues to initialize the entry's data (defaults to None)
for_flash:boolWhether the entry supports flash chips (defaults to True)
name:strThe name of the entry (defaults to a valid default name)
version:intThe entry's version (defaults to None)
archived:boolWhether the entry is archived (defaults to entry's default state on-calc)
data:bytesThe entry's data (defaults to empty)
def __iter__(self) -> Iterator[RealEntry]: (source)
overrides tivars.var.TIEntry.__iter__
Returns
Iterator[RealEntry]An iterator over this matrix's elements in row-major order
@Section()
def calc_data(self) -> bytes: (source)
overrides tivars.var.TIEntry.calc_data

The data section of the entry which is loaded on-calc

@View(calc_data, Bytes)[2:]
def data(self) -> bytes: (source)
overrides tivars.var.TIEntry.data

The entry's user data

def get_min_os(self, data: bytes = None) -> OsVersion: (source)
overrides tivars.var.TIEntry.get_min_os

Determines the minimum OS that supports this entry's data

Parameters
data:bytesThe data to find the minimum support for (defaults to this entry's data)
Returns
OsVersionThe minimum OsVersion this entry supports
def get_version(self, data: bytes = None) -> int: (source)
overrides tivars.var.TIEntry.get_version

Determines the version byte corresponding to given data for this entry type

Entries which could contain non-backwards compatible data are assigned a version byte. If an entry's version exceeds the "version" of a calculator, transfer to the calculator will fail.

Parameters
data:bytesThe data to find the version of (defaults to this entry's data)
Returns
intThe version byte for data
@View(calc_data, Integer)[1:2]
def height(self, value: int) -> int: (source)

The number of rows in the matrix

TI-OS imposes a limit of 99. Additionally, TI-OS imposes a limit of 400 total elements.

@Loader[bytes, bytearray, BytesIO]
def load_bytes(self, data: bytes | BytesIO): (source)
overrides tivars.var.TIEntry.load_bytes

Parameters

def load_data_section(self, data: BytesIO): (source)
overrides tivars.var.TIEntry.load_data_section

Loads the data of this entry from a bytestream

Parameters
data:BytesIOThe source bytes
@Loader[Sequence]
def load_matrix(self, matrix: Sequence[Sequence[RealEntry]]): (source)
