Class PgSphereTranslator.PgSphereGeometryParser

java.lang.Object

adql.translator.PgSphereTranslator.PgSphereGeometryParser

Enclosing class:

PgSphereTranslator

protected static class PgSphereTranslator.PgSphereGeometryParser
extends java.lang.Object

Let parse a geometry serialized with the PgSphere syntax.

There is one function parseXxx(String) for each supported geometry. These functions always return a STCS.Region object, which is the object representation of an STC region.

Only the following geometries are supported:

• spoint => Position
• scircle => Circle
• sbox => Box
• spoly => Polygon

This parser supports all the known PgSphere representations of an angle. However, it always returns angle (coordinates, radius, width and height) in degrees.

Method Detail

parsePoint

public STCS.Region parsePoint(java.lang.String pgsphereExpr)
                       throws ParseException

Parse the given PgSphere geometry as a point.

Parameters:

pgsphereExpr - The PgSphere expression to parse as a point.

Returns:

A STCS.Region implementing a STC Position region.

Throws:

ParseException - If the PgSphere syntax of the given expression is wrong or does not correspond to a point.

parseCircle

public STCS.Region parseCircle(java.lang.String pgsphereExpr)
                        throws ParseException

Parse the given PgSphere geometry as a circle.

Parameters:

pgsphereExpr - The PgSphere expression to parse as a circle.

Returns:

A STCS.Region implementing a STC Circle region.

Throws:

ParseException - If the PgSphere syntax of the given expression is wrong or does not correspond to a circle.

parseBox

public STCS.Region parseBox(java.lang.String pgsphereExpr)
                     throws ParseException

Parse the given PgSphere geometry as a box.

Parameters:

pgsphereExpr - The PgSphere expression to parse as a box.

Returns:

A STCS.Region implementing a STC Box region.

Throws:

ParseException - If the PgSphere syntax of the given expression is wrong or does not correspond to a box.

parsePolygon

public STCS.Region parsePolygon(java.lang.String pgsphereExpr)
                         throws ParseException
