Member Function Documentation

◆ has_padding()

bool has_padding ( ) const
inline

Check whether this has any padding.

Definition at line 777 of file Types.h.

778  {
779  return (_pad_left != 0 || _pad_top != 0 || _pad_right != 0 || _pad_bottom != 0);
780  }

◆ pad()

std::pair<unsigned int, unsigned int> pad ( ) const
inline

Get the padding.

Note
This should only be used when the padding is symmetric.
Returns
a pair: padding left/right, padding top/bottom

Definition at line 742 of file Types.h.

743  {
744  //this accessor should be used only when padding is symmetric
746  return std::make_pair(_pad_left, _pad_top);
747  }
#define ARM_COMPUTE_ERROR_ON(cond)
If the condition is true then an error message is printed and an exception thrown.
Definition: Error.h:337
bool padding_is_symmetric() const
Check whether the padding is symmetric.
Definition: Types.h:732
