Member Function Documentation

void ns3::Hash::Function::Hash64::clear ( )

inlinevirtual

Restore initial state.

Implements ns3::Hash::Implementation.

Definition at line 153 of file hash-function.h.

uint32_t ns3::Hash::Function::Hash64::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 145 of file hash-function.h.

References GetHash64().

Here is the call graph for this function:

uint64_t ns3::Hash::Function::Hash64::GetHash64 ( const char *  buffer, const size_t  size  )

inlinevirtual

Compute 64-bit hash of a byte buffer.

Default implementation returns 32-bit hash, with a warning.

Call clear () between calls to GetHash64() to reset the internal state and hash each buffer separately.

If you don't call clear() between calls to GetHash64, 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

64-bit hash of the buffer
