te::gm::Geometry * EWKBReader::read ( const char *  ewkb)
static

It returns a valid geometry from a given EWKB.

Parameters
ewkbA valid EWKB geometry.
Returns
A geometry created from reading the EWKB. The caller of this method will take the ownership of the returned geometry.

te::gm::Geometry * EWKBReader::readHex ( const char *  hewkb)
static

It returns a valid geometry from a given hex-encoded EWKB.

Parameters
hewkbAn hex-encoded EWKB geometry.
Returns
A geometry created from reading the HEWKB. The caller of this method will take the ownership of the returned geometry.
