Member Function Documentation

deserialize()

bool ts::LCTHeader::deserialize	(	const uint8_t *&	addr,
		size_t &	size
	)

Deserialize a binary LCT header.

Parameters

[in,out]	addr	Address of binary area. Updated to point after LCT header.
[in,out]	size	Size of binary area. Updated with remaining size after deserializing the LCT header.

Returns

True on success, false on error. Same as valid field.

toString()

virtual UString ts::LCTHeader::toString ( ) const

overridevirtual

Convert to a string object.

Returns

This object, converted as a string.

Implements ts::StringifyInterface.
