ListType

using sese::IOBuf::ListType = std::list<Node>

Node

using sese::IOBuf::Node = std::unique_ptr<IOBufNode>

Type of node.

Member Function Documentation

clear()

void sese::IOBuf::clear

(

)

Release all nodes.

getReadableSize()

size_t sese::IOBuf::getReadableSize ( ) const

nodiscardnoexcept

Get the current readable size.

getTotalSize()

size_t sese::IOBuf::getTotalSize ( ) const

nodiscardnoexcept

Get the current total size of all node contents.

peek()

int64_t sese::IOBuf::peek ( void * buffer, size_t length )

overridevirtual

Peek at the content from one or more nodes

Parameters

buffer	Buffer
length	Buffer size

Returns

Actual size obtained

Implements sese::io::PeekableStream.

length	Buffer size

Returns

Actual size obtained

Implements sese::io::InputStream.

trunc()

int64_t sese::IOBuf::trunc ( size_t length )

overridevirtual

Step through the content from one or more nodes

Parameters

length

Step size

Returns

Actual step size

Implements sese::io::PeekableStream.
