Class XbaseRecordWriter

java.lang.Object

com.revolsys.io.AbstractObjectWithProperties

com.revolsys.io.AbstractWriter<Record>

com.revolsys.io.AbstractRecordWriter

com.revolsys.io.xbase.XbaseRecordWriter

All Implemented Interfaces:

ObjectWithProperties, Writer<Record>, AutoCloseable

Direct Known Subclasses:

ShapefileRecordWriter

public class XbaseRecordWriter
extends AbstractRecordWriter

Xbase attributes suffer a number of limitations:

• Field names can only be up to 10 characters long. If required names will be truncated to 10 character. Duplicate field names will have a sequential number appended to avoid duplicates. Name may be truncated again to fit the sequential number.
• Only Boolean, Number, String and Date (YYYYMMDD) field types are supported. Other types will be converted to strings.
• String can have a maximum length of 254 characters. If length < 1 then length of 254 will be used. Strings will be silently truncated to 254 characters. Strings are left aligned in the field and padded with spaces instead of a null terminator.
• boolean fields have length 1 and scale 0.
• byte fields have length 3 and scale 0.
• short fields have length 5 and scale 0.
• int fields have length 10 and scale 0.
• long and BigInteger fields have length 18 and scale 0.
• float, double, Number fields can have a maximum length of 18 characters. If length < 1 then length of 18 will be used. If scale is < 0 scale of 3 is used. Scale must be <= 15. Scale must be <= length -3 to allow for '-' sign and digit and a '.'. NOTE: For floating point numbers an explicit length and scale is recommended.
