Constructor Details

ST_FromBinary

ST_FromBinary(SQLMM operation,
 Expression<? super R,?>[] parameters,
 Geometries<G> library)

Creates a new function for the given parameters.

Method Details

recreate

public Expression<R,Object> recreate(Expression<? super R,?>[] effective)

Creates a new expression of the same type than this expression, but with an optimized geometry. The optimization may be a geometry computed immediately if all operator parameters are literals.

Specified by:

recreate in interface Optimization.OnExpression<R,G>

Specified by:

recreate in class GeometryParser<R,G>

Parameters:

effective - the expressions to use as a replacement of this expression parameters.

Returns:

the new expression, or this if unsupported.

inputName

final String inputName()

Returns the name of the kind of input expected by this expression.

Specified by:

inputName in class GeometryParser<R,G>

Returns:

"text" or "wkb".

parse

protected GeometryWrapper<G> parse(Object value)
                            throws Exception

Parses the given value.

Specified by:

parse in class GeometryParser<R,G>

Parameters:

value - the WKB value.

Returns:

the geometry parsed from the given value.

Throws:

ClassCastException - if the given value is not a ByteBuffer or an array of bytes.

Exception - if parsing failed for another reason. This is an implementation-specific exception.
