Function Usage

Checks whether the input pointer is null. If the pointer is null, true is returned and an error log is printed. Otherwise, false is returned.

Prototype

  • static inline bool IsNullptr(const aclTensor *tensor, const char *name)
  • static inline bool IsNullptr(const aclTensorList *tensorList, const char *name)
  • static inline bool IsNullptr(const aclScalar *scalar, const char *name)
  • static inline bool IsNullptr(const aclIntArray *intArr, const char *name)
  • static inline bool IsNullptr(const aclBoolArray *boolArr, const char *name)
  • static inline bool IsNullptr(const aclFloatArray *floatArr, const char *name)

Parameters

Parameter

Input/Output

Description

tensor

Input

Pointer to be checked. It can be of the aclTensor *, aclTensorList *, aclScalar *, aclIntArray *, aclBoolArray *, or aclFloatArray * type.

name

Input

Name of the checked pointer. If the checked pointer is null, the name is printed in the error log.

Returns

Bool type. true: nullptr; false: not nullptr.

Constraints

None
