All Implemented Interfaces:

Serializable, Cloneable, Map<String,Object>, ICCEEConstants

public class DynDataMap
extends HashMap<String,Object>
implements ICCEEConstants

Instance of dynamic data.

Dynamic data is a map with reference to a DynDataDefinition. The definition is linked by its id.

The map may contain other DynDataMap (1:1) defintions and may contain lists of DyanDataMap definitions (1:n).

The get(Object) method can be used either in simpley way, passing the key that is stored inside of the instance. Or you can pass complete expressions to access sub-objects or to execute formulas on values.

DynDataMap objects are heavily used within the creation of PDF documents within the eclnt_jsrxml PDF generation framework.

Constructor Details

DynDataMap

public DynDataMap(DynDataReaderContext ddrContext,
 String dataDefinitionId,
 DynDataMap parentDataMap)

The preferred way of creating DynDataMap instances is to use the class DynDataReader. This class implicitly uses this constructor.

Method Details

getParent

public DynDataMap getParent()

setParent

public void setParent(DynDataMap parent)

getDataDefinitionId

public String getDataDefinitionId()

getCurrentDataRequestEntryPoint

public DynDataMap getCurrentDataRequestEntryPoint()

Access from outside can be done in the way: get("data").get("xxx").get("yyy"). In this case the DynDataMap receiving the get("data") is the entry point.

get

public Object get(Object key)

Specified by:

get in interface Map<String,Object>

Overrides:

get in class HashMap<String,Object>

getContent

public Object getContent(Object key)

Direct access into the map. While the get(Object) does some interpretation of the key, this method returns the data value that is contained in the map. This is the "real", direct access into the map.

getAttributeValue

public Object getAttributeValue(String name)

getObjectMap

public DynDataMap getObjectMap(String dataDefinitionId)

getObjectMapList

public List<DynDataMap> getObjectMapList(String dataDefinitionId)

getAttributeValueForChainOfKeys

public Object getAttributeValueForChainOfKeys(String[] keys)

getExpressionValue

public Object getExpressionValue(String expression)

Resolve value of expression "#{xxx.yyy.zzz}. Null is returned in case of malformed expressions.

toString

public String toString(int level)
