Detailed Description

An implementation of the ICziWriterInfo-interface.

Constructor & Destructor Documentation

CCziWriterInfo() [1/2]

libCZI::CCziWriterInfo::CCziWriterInfo ( const GUID &  fileGuid, int  mMin = 1, int  mMax = -1  )

inlineexplicit

Constructor - leaves the bounds undefined.

Parameters

fileGuid	The GUID to be set as the CZI's file-guid. If this is GUID_NULL (all 0's), then we will create a new Guid and use it.
mMin	(Optional) The minimum for the M-index (inclusive).
mMax	(Optional) The maximum for the M-index (inclusive).

CCziWriterInfo() [2/2]

libCZI::CCziWriterInfo::CCziWriterInfo ( const GUID &  fileGuid, const IDimBounds &  bounds, int  mMin = 1, int  mMax = -1  )

inline

Constructor.

Parameters

fileGuid	The GUID to be set as the CZI's file-guid. If this is GUID_NULL (all 0's), then we will create a new Guid and use it.
bounds	The bounds.
mMin	(Optional) The minimum for the M-index (inclusive).
mMax	(Optional) The maximum for the M-index (inclusive).

Member Function Documentation

GetDimBounds()

const IDimBounds* libCZI::CCziWriterInfo::GetDimBounds ( ) const

inlineoverridevirtual

Gets bounds for the subblocks we are going to add to the CZI. If this is a valid bounds, then the coordinates of each subblock added are checked against this bounds. In case of a violation, an LibCZIWriteException-exception is thrown.

Returns

Null if the bounds is not specified, else the bounds for the subblock's coordinates we want to add.

Implements libCZI::ICziWriterInfo.

GetFileGuid()

const GUID& libCZI::CCziWriterInfo::GetFileGuid ( ) const

inlineoverridevirtual

Gets file's unique identifier. If we report GUID_NULL, then the file-writer will create a GUID on its own.

Returns

The file's unique identifier.

Implements libCZI::ICziWriterInfo.

SetDimBounds()

void libCZI::CCziWriterInfo::SetDimBounds ( const IDimBounds *  bounds )

inline

Sets the bounds. If null is specified, then we report "no valid bounds" with 'GetDimBounds()'.

Parameters

bounds

The bounds (may be nullptr).

SetMIndexBounds()

void libCZI::CCziWriterInfo::SetMIndexBounds ( int  mMin, int  mMax  )

inline

Sets the M-index bounds. If mMax < mMin, then we report "no valid M-index-bounds" with 'TryGetMIndexMinMax'.

Parameters

mMin	The minimum value for the m-Index (inclusive).
mMax	The maximum value for the m-Index (inclusive).

SetReservedSizeForAttachmentsDirectory()

void libCZI::CCziWriterInfo::SetReservedSizeForAttachmentsDirectory ( bool  reserveSpace, size_t  s  )

inline

Sets reserved size for the "attachments directory".

Parameters

reserveSpace	True to reserve space.
s	The size (in bytes) to reserve for the "attachments directory".

SetReservedSizeForMetadataSegment()

void libCZI::CCziWriterInfo::SetReservedSizeForMetadataSegment ( bool  reserveSpace, size_t  s  )

inline

Sets reserved size for the "metadata segment".

Parameters

reserveSpace	True to reserve space.
s	The size (in bytes) to reserve for the "metadata segment".

SetReservedSizeForSubBlockDirectory()

void libCZI::CCziWriterInfo::SetReservedSizeForSubBlockDirectory ( bool  reserveSpace, size_t  s  )

inline

Sets reserved size for the "subblock directory".

Parameters

reserveSpace	True to reserve space.
s	The size (in bytes) to reserve for the "subblock directory".

TryGetMIndexMinMax()

bool libCZI::CCziWriterInfo::TryGetMIndexMinMax ( int *  min, int *  max  ) const

inlineoverridevirtual

Attempts to get the minimum and the maximum (inclusive) for the m-index. If returning a valid interval (ie. if the return value is true), then the M-coordinate of each subblock added is checked against this. Furthermore, in this case we require that all subblocks have a valid M-index.

Parameters

[out]	min	If non-null will receive the minimum M-index (inclusive).
[out]	max	If non-null will receive the maximum M-index (inclusive).

Returns

True if it succeeds, false the is no bounds for the M-index.

Implements libCZI::ICziWriterInfo.

TryGetReservedSizeForAttachmentDirectory()

bool libCZI::CCziWriterInfo::TryGetReservedSizeForAttachmentDirectory ( size_t *  size ) const

inlineoverridevirtual

Query whether to reserve space for the attachment-directory-segment at the start of the file. If returning true, the value returned for size has the following meaning: if it is >0, it is interpreted as the number of attachment-entries (ie. how many attachments can be put into the CZI). If it is 0 (and returning true), some default is used. If returning false, no space is reserved, and the attachment-directory is put at the end of the CZI. If the reserved space is not sufficient, then the attachment-directory-segment is put at the end of the CZI (and the reserved space is unused).

Parameters

[out]

size

If returning true, then this gives the number of attachment-entries to reserve.

Returns

True if space for the attachment-directory-segment is to be reserved, false otherwise.

Implements libCZI::ICziWriterInfo.

TryGetReservedSizeForMetadataSegment()

bool libCZI::CCziWriterInfo::TryGetReservedSizeForMetadataSegment ( size_t *  size ) const

inlineoverridevirtual

Query whether to reserve space for the metadata-segment at the start of the file. If returning true, the value returned for size has the following meaning: if it is >0, it is interpreted as the number of bytes available for the metadata-segment. If it is 0 (and returning true), some default is used. If returning false, no space is reserved, and the metadata-segment is put at the end of the CZI. If the reserved space is not sufficient, then the metadata-segment is put at the end of the CZI (and the reserved space is unused).

Parameters

[out]

size

If returning true, then this gives the number of bytes to be reserved in the metadata-segment.

Returns

True if space (in bytes) for the metadata is to be reserved, false otherwise.

Implements libCZI::ICziWriterInfo.

TryGetReservedSizeForSubBlockDirectory()

bool libCZI::CCziWriterInfo::TryGetReservedSizeForSubBlockDirectory ( size_t *  size ) const

inlineoverridevirtual

Query whether to reserve space for the subblock-directory-segment at the start of the file. If returning true, the value returned for size has the following meaning: if it is >0, it is interpreted as the number of subblock-entries (ie. how many subblocks can be put into the CZI). If it is 0 (and returning true), some default is used. If returning false, no space is reserved, and the subblock-directory is put at the end of the CZI. If the reserved space is not sufficient, then the subblock-directory-segment is put at the end of the CZI (and the reserved space is unused).

Parameters

[out]

size

If returning true, then this gives the number of subblock-entries to reserve.

Returns

True if space for the subblock-directory-segment is to be reserved, false otherwise.
