Constructor Details

FileGdbTable

public FileGdbTable(Dataset dataset)
             throws IOException

Throws:

IOException

FileGdbTable

public FileGdbTable(Dataset dataset,
 Map<String,FieldMetadata> metadata,
 GdbCatalog catalog)
             throws IOException

Throws:

IOException

Method Details

dataset

public Dataset dataset()

name

public String name()

path

public Path path()

fields

public List<FileGdbField> fields()

field

public Optional<FileGdbField> field(String name)

Looks up a field by name, ignoring case as a fallback.

geomField

public FileGdbGeomField geomField()

Returns the geometry field or null for plain tables.

isFeatureClass

public boolean isFeatureClass()

geomFieldIndex

public int geomFieldIndex()

Index of the geometry field in fields(), or -1 for plain tables.

objectIdFieldIndex

public int objectIdFieldIndex()

Index of the object id field in fields(), or -1 if absent.

crs

public CrsDefinition crs()

domain

public Optional<Domain> domain(String fieldName)

Domain assigned to a field, resolved through the catalog.

rowCount

public long rowCount()

totalRecordCount

public long totalRecordCount()

tableFile

public FileGdbTableFile tableFile()

read

public FileGdbRow read(long objectId)
                throws IOException

Reads a row by its one based object id, or returns null if absent.

Throws:

IOException

query

public FileGdbTable.QueryResult query(ch.so.agi.filegdb.geometry.Envelope filter)
                               throws IOException

Inclusive geometry-envelope intersection. Foreign geometry-cell indexes cannot prove envelope intersection (e.g. a rectangle inside a polygon hole), so use a scan for those.

Throws:

IOException

query

public FileGdbTable.QueryResult query(ch.so.agi.filegdb.geometry.Envelope filter,
 boolean useIndex)
                               throws IOException

Throws:

IOException

iterator

public Iterator<FileGdbRow> iterator()

Specified by:

iterator in interface Iterable<FileGdbRow>

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Throws:

IOException
