Houdini 20.5 hapi

hapi.getAttributeStringArrayData function

Get array attribute string data.

Usage

getAttributeStringArrayData(session: hapi.Session, node_id: int, part_id: int, name: str, attr_info: hapi.AttributeInfo, data_fixed_length: int, start: int, sizes_fixed_length: int) → (list of int, list of int)

Get array attribute string data. Each entry in an array attribute can have varying array lengths. Therefore the array values are returned as a flat array, with another sizes array containing the lengths of each array entry. Note that the string handles returned are only valid until the next time this function is called.

session

The session of Houdini you are interacting with. See hapi.Session for more on sessions. Pass None to just use the default in-process session.

node_id

The node id.

part_id

The part id.

name

Attribute name.

attr_info

hapi.AttributeInfo used as input for the. totalArrayElements. Also contains some sanity checks like data type. Generally should be the same struct returned by hapi.getAttributeInfo.

data_fixed_length

start

First index of range. Must be at least 0 and at most hapi.AttributeInfo.count - 1.

sizes_fixed_length

Must be at least 0 and at most hapi.AttributeInfo.count - start. Note, if 0 is passed for length, the function will just do nothing and return hapi.result.Success.

The string handles should be used to retrieve the strings immediately and are invalidated when another call to get this attribute’s data is made.

Returns a tuple of (data_fixed_array, sizes_fixed_array).
