Basic Sparse Rules

The following variable block rules allow to copy a block of variables within a dictionary (like Copy and CopyC), or to obtain a copy of a block of variables defined in an Entity variable (like GetValue and GeValueC).

CopyBlock

Block(Numerical) CopyBlock(Block(Numerical) valueBlock)

Copy of a block of numerical variables.

Example

In this example, the block of variables named Items is copied to a new block named Words. Each variable has a unique name within the whole dictionary, and a unique VarKey within its block. The variables of the input block are copied to those of the output block having the same VarKey.

Dictionary Document
{
    Categorical DocId;
    Categorical Label;
    {
    Numerical item1; <VarKey=1>
    Numerical item2; <VarKey=2>
    …
    } Items ;
    {
    Numerical archive; <VarKey=1>
    Numerical name; <VarKey=2>
    …
    } Words = CopyBlock(Items) ;
};

CopyBlockC

Block(Numerical) CopyBlockC(Block(Categorical) valueBlock)

Copy of a block of categorical variables.

GetBlock

Block(Numerical) GetBlock(Block(numerical) valueBlock)

Access to a block of numerical variables of an entity.

In the following example, the block of variables named Items in the Entity(Document) variable CurriculumVitae is accessed in a new block named CVWords. In the main entity.

Example

Root Dictionary Applicant(id_applicant)
{
    Categorical id_applicant ;
    Categorical Name ;
    Entity(Document) CurriculumVitae ;
    Entity(Document) MotivationLetter ;
    {
    Numerical archive ; <VarKey=1>
    Numerical name ; <VarKey=2>
    …
    } CVWords = GetBlock(CurriculumVitae, items) ;
};

Dictionary Document(id_applicant)
{
    Categorical id_applicant ;
    {
    Numerical item1 ; <VarKey=1>
    Numerical item2 ; <VarKey=2>
    …
    } Items ;
};

GetBlockC

Block(Categorical) GetBlockC(Block(Categorical) valueBlock)

Access to a block of categorical variables of an entity.
