ContainsItem()

_.Library.Boolean ContainsItem

(

_.Library.String

pItem

)

At minimum, <METHOD>ContainsItem()</METHOD> must always be supported.

It returns 1 iff the given pItem is in the set S.

Reimplemented from AbstractFind.

Find()

_.SQL.AbstractFind Find ( _.Library.List  pQID )

static

Find expects pQID in the format $LB(CUBE,slicerKey).

The appropriate slotNo to read the slicer from the cache

is calculated from the chunk number as needed.

GetChunk()

_.Library.Binary GetChunk

(

_.Library.Integer

pChunk

)

For a given chunk number pChunk, return the corresponding actual bitmap string.

This method must be implemented when FIND is used.

Reimplemented from AbstractFind.

NextChunk()

_.Library.Binary NextChunk

(

_.Library.Integer

pChunk

)

This method simulates the usage of <function>$ORDER()</function> to traverse through the chunks of a bitmap index or a bitmap temp-file that would represent the set S.

For a given chunk number pChunk, find the first chunk number > pChunk and return it in .pChunk, with the method return value being the corresponding actual bitmap string. Return .pChunk="" if none found.

Note that when returning a positive .pChunk, it's OK for the returned bitmap b to have no bits set to 1, including b="" . On the other hand, it's also OK for the method implementation to skip such a chunk and proceed to the next pChunk.

This method must be implemented when FIND is used.

Reimplemented from AbstractFind.

PreviousChunk()

_.Library.Binary PreviousChunk

(

_.Library.Integer

pChunk

)

This method simulates the usage of <function>$ORDER()</function> to traverse backwards through the chunks of a bitmap index or a bitmap temp-file that would represent the set S.

For a given chunk number pChunk, find the first chunk number < pChunk and return it in .pChunk, with the method return value being the corresponding actual bitmap string. Return .pChunk="" if none found.

Note that when returning a positive .pChunk, it's OK for the returned bitmap b to have no bits set to 1, including b="" . On the other hand, it's also OK for the method implementation to skip such a chunk and proceed to the next pChunk.

This method must be implemented when FIND is used.

Reimplemented from AbstractFind.
