Method Detail

splitTableName

public static String[] splitTableName(String fullName)

Returns a pair of strings containing unquoted schema and table names from a full table name. If the fullName contains only one part (table name), the returned array contains a null element at index 0
Examples :

• myschema.mytable -> [myschema, mytable]
• "MySchema"."MyTable" -> [MySchema, MyTable]
• MyTable -> [null, MyTable]
• 2_table -> [null, 2_table]

quote

public static String quote(String s)

Returns s if s is already quoted (with double-quotes), and a quoted version of s otherwise. Returns null if s is null.

unquote

public static String unquote(String s)

Returns s without initial and final double quotes if any. Returns null if s is null.

escapeSingleQuote

public static String escapeSingleQuote(String identifier)

Escape single quotes in the given identifier. Replace all single quotes ("'") by double single quotes ("''")

Parameters:

identifier - string identifier to escape

Returns:

the identifier with single quotes escaped, or identifier if no string found

compose

public static String compose(String schemaName,
                             String tableName)

Compose a concatenated quoted schema name and table name.

Parameters:

schemaName - unquoted schema name

tableName - unquoted table name

normalize

public static String normalize(String name)

Normalize an identifier name (use only lower case)

Parameters:

name - the identifier to normalize

Returns:

the name writen in lowercase

getByteArrayFromGeometry

public static byte[] getByteArrayFromGeometry(org.locationtech.jts.geom.Geometry geom,
                                              int srid,
                                              int dimension)

Converts the geometry into a byte array in EWKB format

Parameters:

geom - the geometry to convert to a byte array

srid - the srid of the geometry

dimension - geometry dimension (2 or 3)

Returns:

a byte array containing a EWKB representation of the geometry

getAttributeType

public static AttributeType getAttributeType(int sqlType,
                                             String dataTypeName)

Returns OpenJUMP attributeType from sql type and datatype name. dataTypeName is nullable. If dataTypeName = "geometry", binary field will be interpreted into AttributeType.GEOMETRY

Parameters:

sqlType - jdbc sql datatype

dataTypeName - native datatype name
