GetInfo()

MAXON_METHOD DataDictionary GetInfo

(

)

const

Returns the info dictionary.

SetInfo()

MAXON_METHOD Result<void> SetInfo

(

const DataDictionary &

info

)

SetInfo the info dictionary of the description.

Parameters

[in]

info

Dictionary with infos.

Returns

OK on success.

GetEntryCount()

MAXON_METHOD Int GetEntryCount

(

)

const

Returns the number of entries in the description.

GetEntries()

MAXON_METHOD Result<BaseArray<DataDictionary> > GetEntries

(

)

const

Returns a array with all entries.

GetEntry()

MAXON_METHOD Result<DataDictionary> GetEntry

(

const InternedId &

id

)

const

Returns a specific entry with the given id. Deprecated. Will be deprecated, use FindEntry instead.

Parameters

[in]

id

Id to return.

Returns

DataDictionary on success. Error if the requested attribute was not in the description.

FindEntry()

MAXON_METHOD Result<DataDictionary> FindEntry

(

const InternedId &

id

)

const

Searches for the occurrence of the entry.

Parameters

[in]

id

Id to search.

Returns

Entry on success. Error if entry is not found.

SetEntry()

MAXON_METHOD Result<Bool> SetEntry	(	const DataDictionary &	props,
		Bool	merge = false
	)

SetEntry description.

Parameters

[in]	props	Properties to set. The DESCRIPTION::BASE::IDENTIFIER will be used as key for the hashmap.
[in]	merge	True if the container should be merged with the existing props im the description. The given props will have priority over the existing.

Returns

true if properties has been changed.

EraseEntry()

MAXON_METHOD Result<void> EraseEntry

(

const InternedId &

id

)

Deletes a attribute from the description.

Parameters

[in]

id

Id of the attribute to delete.

Returns

OK on success.

Reset()

MAXON_METHOD void Reset

(

)

Resets the description and clear all attributes.

IsEqual()

MAXON_METHOD Bool IsEqual	(	const DataDescriptionInterface *	other,
		EQUALITY	equality
	)		const

Compares two descriptions.

Parameters

[in]	other	Other description to compare.
[in]	equality	See @EQUALITY.

Returns

True in equality.

Compare()

MAXON_METHOD COMPARERESULT Compare

(

const DataDescriptionInterface *

other

)

const

Compares the 2 values.

GetHashCode()

MAXON_METHOD HashInt GetHashCode

(

)

const

Returns the hash code of this @CLASS.

Returns

Hash code of this @CLASS.

GetUniqueHashCode()

MAXON_METHOD UniqueHash GetUniqueHashCode

(

)

const

Returns the 128-bit hash value of this @CLASS. The implementation ensures uniform distribution, so for practical purposes you can safely assume that two objects are equal if their hash values are equal.

Returns

Hash value of this @CLASS.

ToString()

MAXON_METHOD String ToString

(

const FormatStatement *

formatStatement = nullptr

)

const

Returns a readable string of the content.

Parameters

[in]

formatStatement

Nullptr or additional formatting instruction. Use "{N}" for nive formatting of the name only. Otherwise the unique id is printed together with the name.

Returns

The converted result.

DescribeIO()

static MAXON_METHOD Result<void> DescribeIO ( const DataSerializeInterface &  stream )

static

Describe all elements of this class for I/O operations.

Parameters

[in]

stream

The stream that is used to register the class members.

Returns

OK on success.
