Constructs a new FixedLengthFieldFormat.

Method Detail

extract

public String extract(UnmarshallingContext context,
                      boolean reportErrors)

Description copied from interface: FieldFormat

Extracts the field text from a record. Returns null if the field was not present in the record.

May return Value.INVALID if the field is invalid, or Value.NIL if the field is explicitly set to nil or null such as in an XML or JSON formatted stream.

Implementations should also remove any field padding before returning the text.

Specified by:

extract in interface FieldFormat

Overrides:

extract in class FlatFieldFormatSupport

Parameters:

context - the UnmarshallingContext holding the record

Returns:

the field text

extractFieldText

public String extractFieldText(UnmarshallingContext context,
                               boolean reporting)

Specified by:

extractFieldText in class FlatFieldFormatSupport

insertFieldText

public void insertFieldText(MarshallingContext context,
                            String fieldText,
                            boolean commit)

Specified by:

insertFieldText in class FlatFieldFormatSupport

getSize

public int getSize()

Description copied from interface: FieldFormat

Returns the size of the field. Fixed length formats should return the field length, while other formats should simply return 1.

Specified by:

getSize in interface FieldFormat

Overrides:

getSize in class FlatFieldFormatSupport

Returns:

the size of the field

setKeepPadding

public void setKeepPadding(boolean keepPadding)

Set to true to keep field padding during unmarshalling.

Parameters:

keepPadding - true to keep padding

Since:

2.0.2

setLenientPadding

public void setLenientPadding(boolean lenientPadding)

Sets whether the padding length is enforced.

Parameters:

lenientPadding - true if not enforced, false otherwise

Since:

2.1.0
