SliceFields (const std::vector< std::string > &keys) | |
Creates a SliceFields from a full set of parameters. More... | |
const std::vector< std::string > | keys () const |
The names of the fields to select. More... | |
const SliceItemPtr | shallow_copy () const override |
Copies this node without copying any associated arrays. More... | |
const std::string | tostring () const override |
Returns a string representation of this slice item (single-line custom format). More... | |
bool | preserves_type (const Index64 &advanced) const override |
Returns true if this slice would preserve an array's slice and therefore should pass on Content::parameters . More... | |
virtual bool | referentially_equal (const SliceItemPtr &other) const override |
Returns true if this slice item has all the same buffers and parameters as other ; false otherwise. More... | |
![]() | |
virtual | ~SliceItem () |
Virtual destructor acts as a first non-inline virtual function that determines a specific translation unit in which vtable shall be emitted. More... | |
