ValueXArray

class dsviper.ValueXArray

Bases: object

A class used to represent a value of type xarray<element_type>. Seamless with a Python seq[object].

Or use Value.create(type_xarray [, initial_value]).

END = 00000000-0000-0000-0000-000000000000

append(value: _InputValues) → ValueUUId

Append value to the end.

at(position: ValueUUId, *, encoded: bool = True) → _OutputValues | None

Return the element at the position or None.

static cast(value: Value) → ValueXArray

Return a xarray<element_type> or raise.

copy() → ValueXArray

Return a deep copy.

static create_position() → ValueUUId

Create and return a position.

description(*, namespace: NameSpace | None = None) → str

Return the description.

disable_position(position: ValueUUId) → None

Disable the position.

extend(values: Sequence | ValueVector) → ValueUUId

Extend by appending the values.

has_position(position: ValueUUId) → bool

Return True if the position exists.

hash() → int

Return the hash value.

index(position: ValueUUId) → int | None

Return the index of the position.

insert(before_position: ValueUUId, value: _InputValues, new_position: ValueUUId | None = None) → ValueUUId

Insert the value before_position and return the new position. Use new_position if specified, else a new position is created.

insert_position(before_position: ValueUUId, new_position: ValueUUId) → None

Insert before_position a new_position.

items() → list[tuple[ValueUUId, Value]]

Return the list of positions with a value.

position(index: int) → ValueUUId | None

Return the position for the index or None.

position_of(value: _InputValues) → ValueUUId | None

Return the position of the value or None.

positions() → list[ValueUUId]

Return the list of positions.

remove(position: ValueUUId) → None

Remove the element at the position.

representation() → str

Return the representation.

set(position: ValueUUId, value: _InputValues)

Set the value at the position.

to_vector() → ValueVector

Convert to a vector<element_type>.

type() → Type

Return the type.

type_code() → str

Return the type code.

type_xarray() → TypeXArray

Return the type xarray<element_type>.
