Builder for SPARQL Ask Queries.
The AskBuilder provides chainable methods to programmatically generate SPARQL Ask Queries. The application order of the methods is not relevant for the resulting query. An ExprFactory is intended for use along with the AskBuilder to generate needed Expr parameter values. An ExprFactory that works with the same prefixes can be obtained with AbstractQueryBuilder.getExprFactory().
The AskBuilder can be used as prepared query. Values for variables in the created query can be set with AbstractQueryBuilder.setVar(Object, Object) and AbstractQueryBuilder.setVar(Var, Node). The method clearWhereValues() allows to clear the set values.

  - addWhereValueVar
```
public AskBuilder addWhereValueVar(Object var)
```
    Description copied from interface: WhereClause
    
    Add a variable or variable and values to the value statement. The first var (or first item in a collection) is converted to a variable using the makeVar strategy. A variable may be added multiple times, doing so will append values to the list of variable values. The order in which variables are added to the values table is preserved. Adding a collection as the var will use the first object in the collection as the var and the remaining objects as values. Values are created using makeNode() strategy except that null values are converted to UNDEF.
    
    Specified by:
    
    addWhereValueVar in interface WhereClause<AskBuilder>
    
    Parameters:
    
    var - The variable or collection to add.
    
    Returns:
    
    The builder for chaining.

```
    Description copied from interface: WhereClause
    
    Add a variable and values to the value statement. The var is converted to a variable using the makeVar strategy. A variable may be added multiple times, doing so will append values to the list of variable values. The order in which variables are added to the values table is preserved. Values are created using makeNode() strategy except that null values are converted to UNDEF.
    
    Specified by:
    
    addWhereValueVar in interface WhereClause<AskBuilder>
    
    Parameters:
    
    var - The variable to add.

  - addWhereValueVars
```
public <K extends Collection<?>> AskBuilder addWhereValueVars(Map<?,K> dataTable)
```
    Description copied from interface: WhereClause
    
    Add a data table to the value statement. Each key in the map is used converted into a variable using the makeVar strategy. The order in which variables are added to the values table is preserved. Variables are added in the iteration order for the map. It may be advisable to use a LinkedHashMap to preserver the insert order.
    Specified by:
    
    addWhereValueVars in interface WhereClause<AskBuilder>
    
    Parameters:
    
    dataTable - The data table to add.
    
    Returns:
    
    The builder for chaining.
    
    See Also:
    Each item in the value collection is converted into a node using makeNode() strategy except that null values are converted to UNDEF. If there are already values in the value statement the data table is adds as follows: If the variable already exists in the table the map values are appended to the list of values If the variable does not exist in the table and there are other variables defined, an appropriate number of nulls is added to the front of the map values to create UNDEF entries for the existing rows If there are variables in the value statement that are not specified in the map additional UNDEF entries are appended to them to account for new rows that are added., AbstractQueryBuilder.makeNode(Object), Converters.makeVar(Object)
  - addWhereValueRow
```
public AskBuilder addWhereValueRow(Object... values)
```
    Description copied from interface: WhereClause
    
    Add objects as a row of values. This method is different from the other methods in that the values are appended to each of the variables in the clause.

Variables will always be in the order added to the values table.
    
    Specified by:
    
    addWhereValueRow in interface WhereClause<AskBuilder>
    
    Parameters:
    
    values - the collection of values to add.
