Detailed Description

Namespace grouping all elements of libLAS public interface.

Note:: User's may notice there is namespace detail nested in the liblas namespace. The detail should be considered as private namespace dedicated for implementation details, so libLAS users are not supposed to access it directly, nor included headers from the detail subdirectory of liblas include folder.

Function Documentation

bool liblas::Create	(	std::ofstream &	ofs,
		std::string const &	filename
	)			`[inline]`

Create file and open to write in binary mode.

The output file is also attached to output stream.

Parameters:

	ofs	- reference to output file stream to which created file is attached
	filename	- name of file to open

Returns:: true if file has been create with success, false otherwise

Exceptions:

No

throw

bool liblas::IsGDALEnabled ( ) [inline]

Check if GDAL support has been built in to libLAS.

bool liblas::IsLibGeoTIFFEnabled ( ) [inline]

Check if GeoTIFF support has been built in to libLAS.

bool liblas::IsLibSpatialIndexEnabled ( ) [inline]

Check if libspatialindex support has been built in to libLAS.

bool liblas::Open	(	std::ifstream &	ifs,
		std::string const &	filename
	)			`[inline]`

Open file to read in binary mode.

The input file is also attached to input stream.

Parameters:

	ifs	- reference to input file stream to which opened file is attached
	filename	- name of file to open

Returns:: true if file has been opened with success, false otherwise

Exceptions:

No

throw

bool liblas::operator!=	(	VariableRecord const &	lhs,
		VariableRecord const &	rhs
	)			`[inline]`

Inequality operator.

Implemented in terms of LASRecordHeader::equal member function.

Exceptions:

No

throw

bool liblas::operator!=	(	Point const &	lhs,
		Point const &	rhs
	)			`[inline]`

Not-equal-to operator implemented in terms of Point::equal method.

bool liblas::operator!=	(	Classification const &	lhs,
		Classification const &	rhs
	)			`[inline]`

Not-equal-to operator implemented in terms of Classification::equal.

template<typename T >

bool liblas::operator!=	(	reader_iterator< T > const &	lhs,
		reader_iterator< T > const &	rhs
	)			`[inline]`

Inequality operator implemented in terms of reader_iterator::equal.

std::ostream& liblas::operator<<	(	std::ostream &	os,
		Classification const &	cls
	)			`[inline]`

The output stream operator is based on std::bitset<N>::operator<<.

It outputs classification flags in form of string. Effects promised as by Standard for Programming Language C++ , 23.3.5.2: Each character is determined by the value of its corresponding bit position in *this. Character position N - 1 corresponds to bit position zero. Subsequent decreasing character positions correspond to increasing bit positions. Bit value zero becomes the character 0, bit value one becomes the character 1.
