Detailed Description

Instances of the Entry class form a hierarchic data structure used to store account information.

Entries can be serialized and deserialized using the parse() and make() methods.

Definition at line 30 of file entry.h.

Constructor & Destructor Documentation

~Entry()

Io::Entry::~Entry ( )

virtual

Destroys the entry.

Definition at line 55 of file entry.cpp.

Entry() [1/2]

Io::Entry::Entry ( const std::string & label = std::string(), NodeEntry * parent = nullptr )

protected

Constructs a new entry with the specified label and parent.

Definition at line 32 of file entry.cpp.

Entry() [2/2]

Io::Entry::Entry ( const Entry & other )

protected

Constructs a copy of another entry.

Remarks

The copy will be parentless and thus not be embedded in the hierarchy of other. Child entries will be copied as well.

Definition at line 45 of file entry.cpp.

Member Function Documentation

accumulateStatistics()

virtual void Io::Entry::accumulateStatistics ( EntryStatistics & stats ) const

pure virtual

Implemented in Io::NodeEntry, and Io::AccountEntry.

clone()

Io::Entry::clone ( ) const

pure virtual

Clones the entry.

Remarks

The copy will be parentless and thus not be embedded in the hierarchy of other. Child entries will be copied as well.

Implemented in Io::NodeEntry, and Io::AccountEntry.

computeStatistics()

EntryStatistics Io::Entry::computeStatistics ( ) const

inline

Computes statistics for this entry.

Remarks

Takes the current instance and children into account but not parents.

Definition at line 107 of file entry.h.

denotedEntryType()

constexpr EntryType Io::Entry::denotedEntryType ( std::uint8_t version )

staticconstexpr

Definition at line 165 of file entry.h.

denotesNodeEntry()

bool Io::Entry::denotesNodeEntry ( std::uint8_t version )

inlinestatic

Definition at line 160 of file entry.h.

index()

int Io::Entry::index ( ) const

inline

Returns the index of the entry within its parent.

Returns -1 for parentless entries.

Definition at line 98 of file entry.h.

isIndirectChildOf()

bool Io::Entry::isIndirectChildOf

(

const NodeEntry *

entry

)

const

Returns an indication whether the instance is an indirect child of the specified entry.

Definition at line 139 of file entry.cpp.

label()

const std::string & Io::Entry::label ( ) const

inline

Returns the label.

Definition at line 70 of file entry.h.

make()

Io::Entry::make ( std::ostream & stream ) const

pure virtual

Serializes the entry to the specified stream.

Implemented in Io::NodeEntry, and Io::AccountEntry.

makeLabelUnique()

void Io::Entry::makeLabelUnique

(

)

Internally called to make the entry's label unique within the parent.

setLabel()

Definition at line 64 of file entry.cpp.

operator=()

Entry & Io::Entry::operator= ( const Entry & other )

delete

parent()

NodeEntry * Io::Entry::parent ( ) const

inline

Returns the parent entry.

Remarks

Returns nullptr for top-level entries.

Definition at line 90 of file entry.h.

parse()

Entry * Io::Entry::parse ( std::istream & stream )

static

Parses an entry from the specified stream.

Exceptions

Throws

ParsingException when a parsing exception occurs.

Definition at line 176 of file entry.cpp.

path() [1/2]

std::list< string > Io::Entry::path

(

)

const

Returns the path of the entry.

Definition at line 154 of file entry.cpp.

path() [2/2]

void Io::Entry::path

(

std::list< std::string > &

res

)

const

Stores to path of the entry in the specified list of string.

Definition at line 164 of file entry.cpp.

setLabel()

void Io::Entry::setLabel ( const std::string & label )

inline

Sets the label.

Remarks

The label might be modified to ensure that each child entry within a certain parent has a unique label.

Definition at line 80 of file entry.h.

setParent()

void Io::Entry::setParent	(	NodeEntry *	parent,
		int	index = -1 )

Sets the parent for the entry.

If an index is specified the entry will be inserted as child at this position. If parent is nullptr, the entry will be parentless.

Remarks

• The label might be adjusted to be unique within the new parent.
• If the entry is just moved within its current parent (parent equals parent()), the specified index doesn't take the entry itself into account as it is removed from the children of parent and then re-inserted at index.

Definition at line 99 of file entry.cpp.

type()

Io::Entry::type ( ) const

pure virtual

Returns the type of the entry.

Implemented in Io::NodeEntry, and Io::AccountEntry.
