Class ResultNode

java.lang.Object
  com.esri.adf.web.data.results.ResultNode

All Implemented Interfaces:

Serializable

public class ResultNode
extends Object
implements Serializable

The ResultNode object wraps the actual result objects that are added to the WebResults. The ResultNode is the one which actually invokes the appropriate methods on the actual results to retrieve the 4 pieces of information expected of a result (display text, details, actions and on-remove).

The ResultNode maintains the metadata for the result in a ResultDescriptor. This metadata includes the methods for the display text, details, actions and on-remove.

Since the ResultNodes are maintained as a tree, each node maintains references to its parent node as well as children nodes.

Constructor Detail

ResultNode

public ResultNode(String stringResult)

Creates a new ResultNode object for this String result.

Same as:

 this(stringResult, ResultDescriptor.STRING_RESULT_DESCRIPTOR, null);
 

Parameters:

stringResult -

ResultNode

public ResultNode(Object result,
                  String displayNameMethodName,
                  String detailsMethodName,
                  Map<String,String> actionMethodNames,
                  String onRemoveMethodName)

Creates a new ResultNode object.

The ResultDescriptor representing the metadata for this result is created by using the various method names provided as arguments to this constructor.

Parameters:

result - the result to be wrapped by this node

displayNameMethodName - the name of the method which returns the display text for the result

detailsMethodName - the name of the method which returns the result details as a java.util.Map of name-value pairs

actionMethodNames - an array of names of methods for performing actions on the result

onRemoveMethodName - the name of the method to be called when the result is removed

ResultNode

public ResultNode(Object result,
                  ResultDescriptor resultDesc)

Creates a new ResultNode object.

The newly created node wraps the given result. The metadata for the result is included in the resultDesc.

Same as:

 this(result, resultDesc, null);
 

Parameters:

result - the result to be wrapped by this node

resultDesc - the ResultDescriptor representing the metadata for this result

ResultNode

public ResultNode(Object result,
                  ResultDescriptor resultDesc,
                  List<? extends ResultNode> children)

Creates a new ResultNode object.

The newly created node wraps the given result. The metadata for the result is included in the resultDesc. Optionally, one can also provide a List of children nodes, if any.

Parameters:

result - the result to be wrapped by this node

resultDesc - the ResultDescriptor representing the metadata for this result

children - the List of children ResultNodes, if any

Method Detail

getDisplayName

public String getDisplayName()

Returns the display name for this result.

The display name is retrieved by invoking the desginated method name on the result.

Returns:

the display name for this result

getDetails

public Map<String,Object> getDetails()

Returns the details for this result. The details are represented as a java.util.Map of name-value pairs.

The details are retrieved by invoking the desginated method name on the result.

Returns:

a java.util.Map of name-value pairs

isHasDetails

public boolean isHasDetails()

Returns true if a details method was designated for this result.

Returns:

true if a details method was designated for this result

getActionNames

public List<String> getActionNames()

Returns a List of action display names for this result.

Returns:

a List of action display names for this result

processAction

public Object processAction(String actionName)

Invokes the action corresponding to the given actionName.

Parameters:

actionName - the name corresponding to which the action is to be invoked

Returns:

the object returned by the action method invoked

onRemove

public Object onRemove()

Invokes the designated on-remove method on this result as well as its children.

Returns:

the object returned by the on-remove method invoked

addChildren

public void addChildren(List<? extends ResultNode> children)

Adds the List of ResultNodes as children of this node.

Parameters:
