writeXML

public final Node writeXML(long options,
                           java.util.HashMap voAttrRules)

Description copied from interface: XMLInterface

Renders data in a canonical XML-format. The classes ViewObjectImpl and ViewRowImpl implement this method to render data in XML.

Use this method whenever data is required in XML format, either to present a UI (after converting XML data into some HTTP format using a stylesheet) or to pass the data as payload for messages via JMS.

The options parameter represents a set of bit flags that will control the writeXML behavior. The following bit flags have been defined:

• public static long XML_OPT_LIMIT_RANGE = 0x00000001 - Controls whether writeXML will only write rows in the range. If this flag is off, all rows in the row set will be written. If this flag is on, only rows in the current range will be written.
• public static long XML_OPT_CHANGES_ONLY = 0x00000002 - Controls whether only changed attribute values of an entity row is written. If this is on, only the attributes whose value has been marked as "changed" will be written. If this is off, all attributes (regardless of whether the attribute value has been changed or not) will be written. This flag is relevant only when writing EntityImpl.

The voAttrMap parameter represents in a hashmap, the mapping between a given ViewObject's definition type and the corresponding Attributes/accessors to render. A null entry in the hashmap means, render all attributes and accessors of that viewobject type.

Specified by:

writeXML in interface XMLInterface

Parameters:

options - a set of bit flags that will control the writeXML

voAttrRules - HashMap containing Definition names of ViewObjects and an array of AttributeDef to render for a ViewObject of that definition type.

writeXML

public Node writeXML(int depthCount,
                     long options)

Description copied from interface: XMLInterface

Renders data in a canonical XML-format. The classes ViewObjectImpl and ViewRowImpl implement this method to render data in XML.

Use this method whenever data is required in XML format, either to present a UI (after converting XML data into some HTTP format using a stylesheet) or to pass the data as payload for messages via JMS.

The depthcount parameter represents to what level the rendering should recurse. A depthcount of zero (0) means do not traverse any View Links while rendering. One (1) means traverse the View Links on this object but no View Links thereafter, and so on.

The options parameter represents a set of bit flags that will control the writeXML behavior. The following bit flags have been defined:

• public static long XML_OPT_LIMIT_RANGE = 0x00000001 - Controls whether writeXML will only write rows in the range. If this flag is off, all rows in the row set will be written. If this flag is on, only rows in the current range will be written.
• public static long XML_OPT_CHANGES_ONLY = 0x00000002 - Controls whether only changed attribute values of an entity row is written. If this is on, only the attributes whose value has been marked as "changed" will be written. If this is off, all attributes (regardless of whether the attribute value has been changed or not) will be written. This flag is relevant only when writing EntityImpl.

Specified by:

writeXML in interface XMLInterface

Parameters:

depthCount - represents to what level the rendering should recurse.

options - a set of bit flags that will control the writeXML behavior.
