Field Detail

llb

protected Point llb

The lower left bottom corner of the box.

urt

protected Point urt

The upper right top corner of the box.

Constructor Detail

PGboxbase

protected PGboxbase(String type)

Constructs an instance.

Parameters:

type - type of this PGobject

PGboxbase

protected PGboxbase(String type,
                    Point llb,
                    Point urt)

Constructs an instance.

Parameters:

type - type of this PGobject

llb - lower left Point

urt - upper right Point

PGboxbase

protected PGboxbase(String type,
                    String value)
             throws SQLException

Constructs an instance.

Parameters:

type - type of this PGobject

value - WKT

Throws:

SQLException

Method Detail

equals

public boolean equals(@Nullable
                      Object obj)

Overrides:

equals in class org.postgresql.util.PGobject

getLLB

public Point getLLB()

Returns the lower left bottom corner of the box as a Point object

Returns:

lower left bottom corner of this box

getPrefix

protected abstract String getPrefix()

The Prefix we have in WKT rep. I use an abstract method here so we do not need to replicate the String object in every instance.

Returns:

the prefix, as a string

getSrid

public int getSrid()

The OGIS geometry type number of this geometry.

Returns:

the SRID of this geometry

getURT

public Point getURT()

Returns the upper right top corner of the box as a Point object

Returns:

upper right top corner of this box

getValue

@Nonnull
public String getValue()

Overrides:

getValue in class org.postgresql.util.PGobject

hashCode

public int hashCode()

Overrides:

hashCode in class org.postgresql.util.PGobject

is3d

public abstract boolean is3d()

Checks if this box is 3d.

Returns:

true on success, else false

isEmpty

public boolean isEmpty()

Ist this box empty, so does it contain no coordinates?

Returns:

true on success, else false

setSrid

public void setSrid(int srid)

Recursively sets the srid on this geometry and all contained subgeometries

Parameters:

srid - the SRID for this geometry

setValue

public void setValue(@Nonnull
                     String value)
              throws SQLException

Overrides:

setValue in class org.postgresql.util.PGobject

Throws:

SQLException

toString

public String toString()

Unlike geometries, toString() does _not_ contain the srid, as server-side PostGIS cannot parse this.

Overrides:

toString in class org.postgresql.util.PGobject

Returns:

String representation of this box
