Konstruktordetails

MultiGeometry

protected MultiGeometry(int type)

Constructs an instance with the specified type.

Parameter:

type - int value corresponding to the geometry type

MultiGeometry

protected MultiGeometry(int type,
 Iterable<? extends T> geoms)

Constructs an instance with the specified type and geometries.

Parameter:

type - int value corresponding to the geometry type

geoms - geometries

Methodendetails

add

public void add(T geom)

Adds a geometry.

Parameter:

geom - geometry

addAll

public void addAll(Iterable<? extends T> geoms)

Adds all given geometries.

Parameter:

geoms - geometries

checkConsistency

public boolean checkConsistency()

Beschreibung aus Klasse kopiert: Geometry

Do some internal consistency checks on the geometry. Currently, all Geometries must have a valid dimension (2 or 3) and a valid type. Composed geometries must have all equal SRID, dimensionality and measures, as well as that they do not contain NULL or inconsistent subgeometries. BinaryParser and WKTParser should only generate consistent geometries. BinaryWriter may produce invalid results on inconsistent geometries.

Setzt außer Kraft:

checkConsistency in Klasse Geometry

Gibt zurück:

true if all checks are passed.

equals

public boolean equals(@Nullable
 Object other)

Beschreibung aus Klasse kopiert: Geometry

java.lang.Object equals implementation

Setzt außer Kraft:

equals in Klasse Geometry

Parameter:

other - geometry to compare

Gibt zurück:

true if equal, false otherwise
