111 * \brief Load multi-pass insert settings from JSON string
112 *
113 * This function can be used to change settings for insert queries
114 * in multi-pass insert mode (see 'pointInsertMode' in the database
115 * creation settings). To be applied, the settings must be loaded
116 * before the first call of next(). For settings that have not been
117 * explicitly specified, the default value is used. The settings are
118 * not saved in the database. When parsing the JSON string fails, an
119 * exception is thrown.
120 *
121 * Supported settings:
122 *
123 * - temporary_file_path (string):
124 * Path of the temporary file; if not specified, null or an
125 * empty string, then the database path with suffix ".temp"
126 * is used.
127 * Default: empty
128 *
129 * - points_per_block (integer [1]):
130 * Inserted points are grouped into blocks with this number
131 * of points before they are processed further.
132 * Default: 1048576 (= 16 * 65536)
133 *
134 * - initial_voxel_size (float [m]):
135 * Inserted points are grouped into voxels with this edge
136 * length in meters. The value must be a power of two of the
137 * resolution of the point coordinates (usually 0.00025 m).
138 * After all points have been inserted, voxels are combined
139 * or subdivided to achieve the desired maximum number of
140 * points per voxel set in the database creation settings
141 * (see 'chunkSize').
142 * Default: 2.048 m
143 *
144 * Example JSON string:
145 *
146 * {
147 * "temporary_file_path": "",
148 * "points_per_block": 1048576,
149 * "initial_voxel_size": 2.048

158 * \brief Bind attribute buffer
159 *
160 * Use this function to define a source buffer for a point attribute.
161 * Exactly one buffer can be defined for an attribute (i.e. only the
162 * most recently defined buffer will be used).
163 *
164 * You can but don't need to define a buffer for each attribute. If
165 * no buffer is defined for an attribute, the attribute's default
166 * value will be used instead.
167 *
168 * The buffer is expected to be n*s*d bytes large, where
169 * __n__ is the number of points defined in next(),
170 * __s__ is the size of one element as defined by 'dataType' and
171 * __d__ is the number of attribute dimensions (elements).
172 *
173 * \note This function just stores the buffer pointer - it does
174 * __NOT__ copy the data contained in the buffer. So make
175 * sure that the buffer remains valid until you call next().
