Method Detail

toProtoSQL

protected SQLOperation toProtoSQL(SpatialOperator op)
                           throws UnmappableException,
                                  FilterEvaluationException

Description copied from class: AbstractWhereBuilder

Translates the given SpatialOperator into an SQLOperation.

Specified by:

toProtoSQL in class AbstractWhereBuilder

Parameters:

op - spatial operator to be translated, must not be null

Returns:

corresponding SQL expression, never null

Throws:

UnmappableException - if translation is not possible (usually due to unmappable property names)

FilterEvaluationException - if the filter contains invalid PropertyNames

toProtoSQL

protected SQLExpression toProtoSQL(PropertyName expr)
                            throws UnmappableException,
                                   FilterEvaluationException

Description copied from class: AbstractWhereBuilder

Translates the given PropertyName into an SQLExpression.

Specified by:

toProtoSQL in class AbstractWhereBuilder

Parameters:

expr - expression to be translated, must not be null

Returns:

corresponding SQL expression, never null

Throws:

UnmappableException - if translation is not possible (usually due to unmappable property names)

FilterEvaluationException - if the filter contains invalid PropertyNames

toProtoSQL

protected SQLExpression toProtoSQL(Literal<?> literal)
                            throws UnmappableException,
                                   FilterEvaluationException

Description copied from class: AbstractWhereBuilder

Overrides:

toProtoSQL in class AbstractWhereBuilder

Parameters:

literal - literal to be translated, must not be null
