Function Documentation

Endianness()

bool OmniSketch::Util::Endianness ( )

inline

Endianness of the platform.

Returns

true on big endian; false on small endian.

IsPrime()

bool OmniSketch::Util::IsPrime

(

int32_t

n

)

Compute primality of a 32-bit number.

Parameters

n	Number to be checked

Returns

true if is a prime; false otherwise.

Warning

n must be positive. Otherwise an exception would be thrown.

Mangle()

template<typename T >

T OmniSketch::Util::Mangle

(

T

key

)

Mangling a multi-byte object.

Template Parameters

T	object type

Parameters

key	the object

Returns

the mangled object

Net2Host16()

uint16_t OmniSketch::Util::Net2Host16

(

uint16_t

val

)

Convert a 2-byte word from network endian to the host endian.

Net2Host32()

uint32_t OmniSketch::Util::Net2Host32

(

uint32_t

val

)

Convert a 4-byte word from network endian to host endian.

NextPrime()

int32_t OmniSketch::Util::NextPrime

(

int32_t

n

)

Find the next prime number.

Parameters

n	Starting number

Returns

Next prime number

Warning

n must be positive. Otherwise an exception would be thrown.
