Method Detail

fromBinary

public static Guid.GUID fromBinary(byte[] data)

From binary.

Parameters:

data - the data

Returns:

the guid

fromString

public static Guid.GUID fromString(String guid)

Returns:

the string

writeFieldsToMemory

protected void writeFieldsToMemory()

Write fields to backing memory.

getFieldOrder

protected List getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Specified by:

getFieldOrder in class Structure

Returns:

ordered list of field names
