Hello,
First thank you for your simple yet powerful library to manipulate caches!
I have an issue when I run this following code, with a bgeo file of about 8.6G:

std::ifstream in( filename.c_str(), std::ios_base::in | std::ios_base::binary );
houio::HouGeo::Ptr houGeo;
houGeo = houio::HouGeoIO::import(&in);

The import raises an std::bad_alloc.

Is this case a known issue? Thank you for your time.
Cheers,

I have discovered that houio::json::Token::event() is not handling uniform array of signed int8 type.

This sort of data is present in BGEO mesh of type Polygon

sphere_Polygon.zip

I do have a fix for it but it is unsatisfactory because I am unable to propagate the changes all the way down to jsonUA template class to handle "sbyte" as I am not familiar with the TTL code base.

Hi,

String attributes are not stored by points.

When iterating through houio::HouGeo::AttributeAdapter::Ptr, (retrieved with houio::HouGeo::getPointAttributeNames() ), string attributes are not stored by points.
HouGeo::HouAttribute::getString() only returns unique values of a specific attribute.
For instance, there are 10 points with a string attribute.
The value of this attribute is "A" or "B" according to point id (even or odd).
attribute->getNumElements() returns 2 instead of 10

Is there an index by point somewhere to get the value of this attribute for each point ?

Using the Topology reference object returned by the houio::HouGeo pointer via the method getTopology(), I found the object lacks information to build a topology for mesh export

I noticed there are different Topology classes, one from HouGeoAdapter another one from HouTopology

Basically, I need to get the one from HouTopology as it has additional information indexBuffer whereas the other Topology does not have that.

Why are they different ?
