public interface XMLInterface

Field Summary

static int	XML_IGNORE_DEPTH_COUNT
static long	XML_OPT_ALL_ROWS Bit flag to indicate that all rows will be rendered in XML in the writeXML() method.
static long	XML_OPT_ASSOC_CONSISTENT Bit flag to indicate that attribute accessors that return a RowSet should set the AssociationConsistent flag on, so that new (unposted) rows for the RowSet are also included in the output.
static long	XML_OPT_CHANGES_ONLY For internal framework use only.
static long	XML_OPT_LIMIT_RANGE Bit flag to indicate that rows in the current range will be rendered in XML in the writeXML() method.
static int	XML_PASSIVATION_USE For internal framework use only.

Method Summary

void	readXML(Element elem, int depthCount)
void	readXML(Element elem, int depthCount, XSLStylesheet xslt)
Node	writeXML(int depthCount, long options) Renders data in a canonical XML-format.
Node	writeXML(int depthCount, long options, XSLStylesheet xslt)
Node	writeXML(long options, java.util.HashMap voAttrMap) Renders data in a canonical XML-format.
Node	writeXML(long options, java.util.HashMap voAttrMap, XSLStylesheet xslt)

Field Detail

XML_OPT_ALL_ROWS

static final long XML_OPT_ALL_ROWS

Bit flag to indicate that all rows will be rendered in XML in the writeXML() method.

Constant Field Values

XML_OPT_LIMIT_RANGE

static final long XML_OPT_LIMIT_RANGE

Bit flag to indicate that rows in the current range will be rendered in XML in the writeXML() method. This flag does not work with forward only VOs.

See Also:

Constant Field Values

XML_OPT_ASSOC_CONSISTENT

static final long XML_OPT_ASSOC_CONSISTENT

Bit flag to indicate that attribute accessors that return a RowSet should set the AssociationConsistent flag on, so that new (unposted) rows for the RowSet are also included in the output. When this flag is set, the RowSet used for rendering XML is not set to forward only mode.

Constant Field Values

XML_PASSIVATION_USE

static final int XML_PASSIVATION_USE

For internal framework use only.

XML_OPT_CHANGES_ONLY

Method Detail

writeXML

Node writeXML(int depthCount,
              long options)

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.

Parameters:

depthCount - represents to what level the rendering should recurse.

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

writeXML

Node writeXML(int depthCount,
              long options,
              XSLStylesheet xslt)

readXML

void readXML(Element elem,
             int depthCount)

readXML

void readXML(Element elem,
             int depthCount,
             XSLStylesheet xslt)

writeXML

Node writeXML(long options,
              java.util.HashMap voAttrMap)

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.

Parameters:

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

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

writeXML

Node writeXML(long options,
              java.util.HashMap voAttrMap,
              XSLStylesheet xslt)
