Method Detail

insertValue

public boolean insertValue(MarshallingContext context,
                           java.lang.Object value)

Description copied from interface: FieldFormat

Inserts a value into a record. This method is called before type conversion. If the method returns false, type conversion is invoked and FieldFormat.insertField(MarshallingContext, String) is called. If the method returns true, FieldFormat.insertField(MarshallingContext, String) is not invoked.

Specified by:

insertValue in interface FieldFormat

Parameters:

context - the MarshallingContext

value - the value to insert into the record

Returns:

true if type conversion is required and FieldFormat.insertField(MarshallingContext, String) must be invoked, false otherwise

insertField

public void insertField(MarshallingContext context,
                        java.lang.String fieldText)

Description copied from interface: FieldFormat

Inserts field text into a record.

Specified by:

insertField in interface FieldFormat

Parameters:

context - the MarshallingContext holding the record

fieldText - the field text to insert into the record

insertText

protected abstract void insertText(XmlMarshallingContext context,
                                   java.lang.String text)

Inserts a field into the record during marshalling.

Parameters:

context - the XmlMarshallingContext holding the record

text - the field text to insert

extract

public java.lang.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

Parameters:

context - the UnmarshallingContext holding the record

Returns:

the field text

extractText

protected abstract java.lang.String extractText(XmlUnmarshallingContext context)

Extracts a field from a record during unmarshalling.

Parameters:

context - the XmlUnmarshallingContext holding the record

Returns:

the extracted field text

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

Returns:

the size of the field

getName

public java.lang.String getName()

Returns the field name.

Returns:

the field name

setName

public void setName(java.lang.String name)

Sets the field name.

Parameters:

name - the field name

isLazy

public boolean isLazy()

Description copied from interface: FieldFormat

TODO rename isLazy to something better?? Returns whether this field is optionally present in the record.

Specified by:

isLazy in interface FieldFormat

Returns:

true if lazy, false otherwise

setLazy

public void setLazy(boolean lazy)

getPadding

public FieldPadding getPadding()

Returns the field padding, or null if the field text is not padded.

Returns:

the field padding or null

setPadding

public void setPadding(FieldPadding padding)

toParamString

protected void toParamString(java.lang.StringBuilder s)

Called by toString() to append attributes of this field.

Parameters:

s - the text to append
