Constructor Detail

OperandEvaluator

public OperandEvaluator(ValueFactory factory,
                        Map<String,Value> variables)

Deprecated.

Creates an operand evaluator for the given value factory and set of bind variables.

Parameters:

factory - value factory

variables - bind variables

Method Detail

getValue

public Value getValue(StaticOperand operand,
                      int type)
               throws RepositoryException

Deprecated.

Throws:

RepositoryException

getValue

public Value getValue(StaticOperand operand)
               throws RepositoryException

Deprecated.

Returns the value of the given static operand (literal or bind variable).

Parameters:

operand - static operand to be evaluated

Returns:

evaluated value

Throws:

RepositoryException - if a named bind variable is not found, or if the operand type is unknown

getValue

public Value getValue(Operand operand,
                      Row row)
               throws RepositoryException

Deprecated.

Returns the value of the given operand in the context of the given row. This is a convenience method that uses a somewhat lossy best-effort mapping to evaluate multi-valued operands to a single value. Use the getValues(Operand, Row) method for more accurate results.

Parameters:

operand - operand to be evaluated

row - query result row

Returns:

evaluated value

Throws:

RepositoryException

getValues

public Value[] getValues(Operand operand,
                         Row row)
                  throws RepositoryException

Deprecated.

Evaluates the given operand in the context of the given row.

Parameters:

operand - operand to be evaluated

row - query result row

Returns:

values of the operand at the given row

Throws:

RepositoryException - if the operand can't be evaluated
