unsigned short CppAD::local::local_hash_code

(

const Value &

value

)

General purpose hash code for an arbitrary value.

Template Parameters

Value

is the type of the argument being hash coded. It should be a plain old data class; i.e., the values included in the equality operator in the object and not pointed to by the object.

Parameters

value

the value that we are generating a hash code for. All of the fields in value should have been set before the hash code is computed (otherwise undefined values are used).

Returns

is a hash code that is between zero and CPPAD_HASH_TABLE_SIZE - 1.

Checked Assertions

• std::numeric_limits<unsigned short>::max() >= CPPAD_HASH_TABLE_SIZE
• sizeof(value) is even
• sizeof(unsigned short) == 2
