Member Function Documentation

Data()

void * xgboost::common::MallocResource::Data ( )

inlineoverridevirtual

Implements xgboost::common::ResourceHandler.

Resize()

template<bool force_malloc = false>

void xgboost::common::MallocResource::Resize ( std::size_t  n_bytes, std::byte  init = std::byte{0}  )

inline

Resize the resource to n_bytes.

Unlike std::vector::resize, it prefers realloc over malloc.

Template Parameters

force_malloc

Force the use of malloc over realloc. Used for testing.

Parameters

n_bytes

The new size.

Size()

std::size_t xgboost::common::MallocResource::Size ( ) const

inlineoverridevirtual

Implements xgboost::common::ResourceHandler.
