Member Function Documentation

void ns3::Hash::Function::Hash32::clear ( )

inlinevirtual

Restore initial state

Implements ns3::Hash::Implementation.

uint32_t ns3::Hash::Function::Hash32::GetHash32 ( const char *  buffer, const size_t  size  )

inlinevirtual

Compute 32-bit hash of a byte buffer

Call clear () between calls to GetHash32() to reset the internal state and hash each buffer separately.

If you don't call clear() between calls to GetHash32, you can hash successive buffers. The final return value will be the cumulative hash across all calls.

Parameters

[in]	buffer	pointer to the beginning of the buffer
[in]	size	length of the buffer, in bytes

Returns

32-bit hash of the buffer

Implements ns3::Hash::Implementation.

Definition at line 123 of file hash-function.h.
