Member Function Documentation

calculateWriteSize()

size_t UDBElement::calculateWriteSize

(

)

Calculates quantity of bytes will be written by writeToBuffer() method.

Returns

Quantity of bytes to be written.

operator!=()

bool UDBElement::operator!=

(

const UDBElement &

other

)

const

operator !=

Parameters

other

UDBElement to be compared.

Returns

true if one of other elements is not equal to this UDBElement corresponding element, false otherwise.

operator=() [1/2]

UDBElement & UDBElement::operator=

(

const UDBElement &

other

)

operator =

Parameters

other

UDBElement to be copied.

Returns

Reference to this UDBElement object.

operator=() [2/2]

UDBElement & UDBElement::operator=

(

(

const UDBElement &

other

)

const

operator ==

Parameters

other

UDBElement to be compared.

Returns

true if all elements of other are equal to this UDBElement corresponding elements, false otherwise.

readFromBuffer()

size_t UDBElement::readFromBuffer	(	const std::vector< char > &	buf,
		const size_t &	start_pos )

Tries to read UDBElement from buffer.

Note

This method can throw std::exception in case of errors.

Parameters

buf	Buffer UDBElement should be read from.
start_pos	Offset of first byte to be read.

Returns

Quantity of bytes have been read.

shrinkToFit()

void UDBElement::shrinkToFit

(

)

Reduces memory usage by freeing unused memory in internal containers.

writeToBuffer()

void UDBElement::writeToBuffer

(

std::vector< char > &

buf

)

Writes this UDBElement to buffer buf.

Parameters

buf	Buffer UDBElement should be written to.
