Method Details

createFilterCapabilities

protected FilterCapabilities createFilterCapabilities()

Description copied from class: FilterToSQL

Sets the capabilities of this filter.

Overrides:

createFilterCapabilities in class FilterToSQL

Returns:

FilterCapabilities for this Filter

visitLiteralGeometry

protected void visitLiteralGeometry(Literal expression)
                             throws IOException

Description copied from class: FilterToSQL

Subclasses must implement this method in order to encode geometry filters according to the specific database implementation

Overrides:

visitLiteralGeometry in class FilterToSQL

Throws:

IOException

visitBinarySpatialOperator

protected Object visitBinarySpatialOperator(BinarySpatialOperator filter,
 PropertyName property,
 Literal geometry,
 boolean swapped,
 Object extraData)

Description copied from class: FilterToSQL

Handles the common case of a PropertyName,Literal geometry binary spatial operator.

Overrides:

visitBinarySpatialOperator in class FilterToSQL

visitBinarySpatialOperator

protected Object visitBinarySpatialOperator(BinarySpatialOperator filter,
 Expression e1,
 Expression e2,
 Object extraData)

Description copied from class: FilterToSQL

Handles the more general case of two generic expressions.

The most common case is two PropertyName expressions, which happens during a spatial join.

Overrides:

visitBinarySpatialOperator in class FilterToSQL

visitBinarySpatialOperator

protected Object visitBinarySpatialOperator(BinarySpatialOperator filter,
 Expression e1,
 Expression e2,
 boolean swapped,
 Object extraData)

pre-5.6 spatial functions.

visitBinarySpatialOperatorEnhanced

protected Object visitBinarySpatialOperatorEnhanced(BinarySpatialOperator filter,
 Expression e1,
 Expression e2,
 boolean swapped,
 Object extraData)

supported if version of MySQL is at least 5.6.
