Detailed Description

A collection of OGRLineString.

Member Typedef Documentation

◆ ChildType

typedef OGRLineString OGRMultiLineString::ChildType

Type of child elements.

Constructor & Destructor Documentation

◆ OGRMultiLineString()

OGRMultiLineString::OGRMultiLineString ( const OGRMultiLineString & other )

default

Copy constructor.

Note: before GDAL 2.1, only the default implementation of the constructor existed, which could be unsafe to use.

Since: GDAL 2.1

Member Function Documentation

◆ accept() [1/2]

virtual void OGRMultiLineString::accept ( IOGRGeometryVisitor * visitor )

inlineoverridevirtual

Accept a visitor.

Reimplemented from OGRMultiCurve.

◆ accept() [2/2]

virtual void OGRMultiLineString::accept ( IOGRConstGeometryVisitor * visitor ) const

inlineoverridevirtual

Accept a visitor.

Reimplemented from OGRMultiCurve.

◆ begin() [1/2]

ChildType** OGRMultiLineString::begin ( )

inline

Return begin of iterator.

Since: GDAL 2.3

◆ begin() [2/2]

const ChildType* const* OGRMultiLineString::begin ( ) const

inline

Return begin of iterator.

Since: GDAL 2.3

◆ CastToMultiCurve()

OGRMultiCurve * OGRMultiLineString::CastToMultiCurve ( OGRMultiLineString * poMLS )

static

Cast to multicurve.

The passed in geometry is consumed and a new one returned.

Parameters

poMLS the input geometry - ownership is passed to the method.

Returns: new geometry.

◆ exportToWkt()

OGRErr OGRMultiLineString::exportToWkt	(	char **	ppszDstText,
		OGRwkbVariant	eWkbVariant = `wkbVariantOldOgc`
	)		const

overridevirtual

Convert a geometry into well known text format.

This method relates to the SFCOM IWks::ExportToWKT() method.

This method is the same as the C function OGR_G_ExportToWkt().

Parameters

ppszDstText	a text buffer is allocated by the program, and assigned to the passed pointer. After use, *ppszDstText should be freed with CPLFree().
eWkbVariant	the specification that must be conformed too : wbkVariantOgc for old-style 99-402 extended dimension (Z) WKB types wbkVariantIso for SFSQL 1.2 and ISO SQL/MM Part 3

Returns: Currently OGRERR_NONE is always returned.

Reimplemented from OGRMultiCurve.

◆ getGeometryName()

const char * OGRMultiLineString::getGeometryName ( ) const

overridevirtual

Fetch WKT name for geometry type.

There is no SFCOM analog to this method.

This method is the same as the C function OGR_G_GetGeometryName().

Returns: name used for this geometry type in well known text format. The returned pointer is to a static internal string and should not be modified or freed.

Reimplemented from OGRMultiCurve.

◆ getGeometryType()

OGRwkbGeometryType OGRMultiLineString::getGeometryType ( ) const

overridevirtual

Fetch geometry type.

Note that the geometry type may include the 2.5D flag. To get a 2D flattened version of the geometry type apply the wkbFlatten() macro to the return result.

This method is the same as the C function OGR_G_GetGeometryType().

Returns: the geometry type code.

Reimplemented from OGRMultiCurve.

◆ hasCurveGeometry()

OGRBoolean OGRMultiLineString::hasCurveGeometry ( int bLookForNonLinear = FALSE ) const

overridevirtual

Returns if this geometry is or has curve geometry.

Returns if a geometry is, contains or may contain a CIRCULARSTRING, COMPOUNDCURVE, CURVEPOLYGON, MULTICURVE or MULTISURFACE.

If bLookForNonLinear is set to TRUE, it will be actually looked if the geometry or its subgeometries are or contain a non-linear geometry in them. In which case, if the method returns TRUE, it means that getLinearGeometry() would return an approximate version of the geometry. Otherwise, getLinearGeometry() would do a conversion, but with just converting container type, like COMPOUNDCURVE -> LINESTRING, MULTICURVE -> MULTILINESTRING or MULTISURFACE -> MULTIPOLYGON, resulting in a "loss-less" conversion.

This method is the same as the C function OGR_G_HasCurveGeometry().

Parameters

bLookForNonLinear set it to TRUE to check if the geometry is or contains a CIRCULARSTRING.

Returns: TRUE if this geometry is or has curve geometry.

Since: GDAL 2.0

Reimplemented from OGRMultiCurve.

◆ isCompatibleSubType()

OGRBoolean OGRMultiLineString::isCompatibleSubType ( OGRwkbGeometryType eSubType ) const

overrideprotectedvirtual

Returns whether a geometry of the specified geometry type can be a member of this collection.

Parameters

eSubType type of the potential member

Returns: TRUE or FALSE

Reimplemented from OGRMultiCurve.

◆ operator=()

OGRMultiLineString & OGRMultiLineString::operator= ( const OGRMultiLineString & other )

Assignment operator.

Note: before GDAL 2.1, only the default implementation of the operator existed, which could be unsafe to use.

Since: GDAL 2.1
