Package ch.so.agi.filegdb.write

Class TableFileWriter

java.lang.Object

ch.so.agi.filegdb.write.TableFileWriter

All Implemented Interfaces:

AutoCloseable

public final class TableFileWriter
extends Object
implements AutoCloseable

Creates and fills a .gdbtable file with its .gdbtablx row index.

Ported from GDAL OpenFileGDB (filegdbtable_write.cpp, filegdbtable_write_fields.cpp). The writer supports sequential object ids, no free list, no attribute indexes and no updates. Optional native spatial indexes are built at close. Fields must be added before the first row is written.

Method Summary

void	addGeometryField(FileGdbGeomField field)
static TableFileWriter	append(Path path, boolean createIndex, Map<String,FieldMetadata> metadata)	Opens a physical table in a private edit workspace.
static TableFileWriter	append(Path path, boolean createIndex, Map<String,FieldMetadata> metadata, Runnable cancellation)
void	close()
static TableFileWriter	create(Path tablePath, ch.so.agi.filegdb.geometry.GeometryKind geometryKind, boolean hasZ, boolean hasM)
List<FileGdbField>	fields()
Path	path()
long	rowCount()
void	setCancellation(Runnable check)
void	setSpatialIndex(boolean enabled)
void	sync()	Patches the header and the row index trailer.
long	totalRecordCount()
void	writeFieldDescriptors()	Writes the field descriptor section and prepares the table for rows.
long	writeRow(Object[] attributeValues, ch.so.agi.filegdb.geometry.FileGdbGeometry geometry)	Writes one feature.
