Constructor & Destructor Documentation

◆ BlobNodeImpl() [1/2]

e57::BlobNodeImpl::BlobNodeImpl ( ImageFileImplWeakPtr  destImageFile,
int64_t  byteCount 

This what caller thinks blob length is

Round segment length up to multiple of 4 bytes

Reserve space for blob in file, extend with zeros since writes will happen at later time by caller

Prepare BlobSectionHeader

Write header at beginning of section

References byteCount(), e57::NodeImpl::destImageFile(), and e57::BlobSectionHeader::sectionLogicalLength.

◆ BlobNodeImpl() [2/2]

e57::BlobNodeImpl::BlobNodeImpl ( ImageFileImplWeakPtr  destImageFile,
int64_t  fileOffset,
int64_t  length 

Init blob object that already exists in E57 file currently reading.

Init state from values read from XML

References e57::NodeImpl::destImageFile().

◆ ~BlobNodeImpl()

e57::BlobNodeImpl::~BlobNodeImpl ( )

Member Function Documentation

◆ byteCount()

int64_t e57::BlobNodeImpl::byteCount ( )

◆ checkLeavesInSet()

void e57::BlobNodeImpl::checkLeavesInSet ( const StringSet pathNames,
NodeImplSharedPtr  origin 

We are a leaf node, so verify that we are listed in set. ???true for blobs? what exception get if try blob in compressedvector?

Implements e57::NodeImpl.

References e57::E57_ERROR_NO_BUFFER_FOR_ELEMENT, e57::NodeImpl::pathName(), and e57::NodeImpl::relativePathName().

◆ isDefined()

bool e57::BlobNodeImpl::isDefined ( const ustring pathName)

We have no sub-structure, so if path not empty return false

Implements e57::NodeImpl.

References e57::NodeImpl::pathName().

◆ isTypeEquivalent()

bool e57::BlobNodeImpl::isTypeEquivalent ( NodeImplSharedPtr  ni)

Same node type?

Downcast to shared_ptr<BlobNodeImpl>

blob lengths must match

ignore blob contents, doesn't have to match

Types match

Implements e57::NodeImpl.

◆ read()

void e57::BlobNodeImpl::read ( uint8_t *  buf,
int64_t  start,
size_t  count 

◆ type()

NodeType e57::BlobNodeImpl::type ( ) const

◆ write()

◆ writeXml()

void e57::BlobNodeImpl::writeXml ( ImageFileImplSharedPtr  imf,
CheckedFile cf,
int  indent,
const char *  forcedFieldName = nullptr
