ListStringSize

Description

Obtains the number of strings on the list of strings for the attribute value.

Prototype

int32_t ListStringSize() const

Parameters

None

Returns

int32_t for the number of strings on the list of strings.

Restrictions

None

Example

The following gives the prototype definition of an operator whose OpType is A, with attribute name set to attr1 and type ListString.

For details about the supported data types of the attribute in the .ATTR API, see API Description.

REG_OP(A)
    .INPUT(x, TensorType({ DT_FLOAT }))
    .OUTPUT(y, TensorType({ DT_FLOAT }))
    .ATTR(attr1, ListString, {})
    .OP_END_FACTORY_REG(A)

In this case, you can use the following API during operator implementation to obtain the size of operator A's attribute attr1.

AttrValue *attr = ctx.GetAttr("attr1");
int32_t size = attr->ListStringSize();
