Method Detail

getObject

public Object getObject(Node node)

Gets an object from the node specified as the argument.

This method can be used only for nodes from 'session' location.

Parameters:

node - node to read the object from

Returns:

object retrieved

Usage examples:

This method can be invoked explicitly, like any other Bluelemon method:

     <blue:call manager="ResourcesManager" method="getObject"
                toVariable="variableName">
       <blue:argument type="node" location="session"
                      name="com/emarson/bluelemon/anObject"/>
     </blue:call>
 

However, in most cases it is more convenient to use the equivalent <get node='...' location='...'> syntax:

     <blue:get node="com/emarson/bluelemon/anObject"
               location="session" toVariable="variableName"/>
 

getValue

public ByteArray getValue(Node node)

Gets a series of bytes from the node specified as the argument.

Parameters:

node - node to read the bytes from

Returns:

bytes read

Usage examples:

This method can be invoked explicitly, like any other Bluelemon method:

     <blue:call manager="ResourcesManager" method="getValue"
                toVariable="variableName">
       <blue:argument type="node" location="permanent"
                      name="com/emarson/bluelemon/example"/>
     </blue:call>
 

However, in most cases it is more convenient to use the equivalent <get node='...' location='...'> syntax:

     <blue:get node="com/emarson/bluelemon/example"
               location="permanent" toVariable="variableName"/>
 

remove

public void remove(Node node)

Removes the content of the node specified as the argument.

This method can be used only for nodes from 'permanent' and 'session' locations.

Parameters:

node - node to remove the content from

Usage examples:

     <blue:call manager="ResourcesManager" method="remove">
       <blue:argument type="node" location="session"
                      name="com/emarson/bluelemon/example"/>
     </blue:call>
 

removePackage

public void removePackage(Node node)

Removes the whole package from the MIDlet environment.

Parameters:

node - node identifying the package to remove

Usage examples:

     <blue:call manager="ResourcesManager" method="removePackage">
       <blue:argument type="byteArr" contextKey="packageDigest"/>
     </blue:call>
 

setObject

public void setObject(Node node,
                      Object object)

Binds a given object to the node specified as the argument.

This method can be used only for nodes from 'session' location.

Parameters:

node - node to store the object

data - object to store

Usage examples:

This method can be invoked explicitly, like any other Bluelemon method:

     <blue:call manager="ResourcesManager" method="setValue">
       <blue:argument type="node" location="session"
                      name="com/emarson/bluelemon/anObject"/>
       <blue:argument type="variable" name="form"/>
     </blue:call>
 

However, in most cases it is more convenient to use the equivalent <set node='...' location='...'> syntax:

     <blue:set node="com/emarson/bluelemon/anObject"
               location="session">
       <blue:argument type="variable" name="form"/>
     </blue:set>
 

setValue

public void setValue(Node node,
                     ByteArray data)

Binds a given series of bytes to the node specified as the argument.

Parameters:

node - node to write the bytes into

data - bytes to write

Usage examples:

This method can be invoked explicitly, like any other Bluelemon method:

     <blue:call manager="ResourcesManager" method="setValue">
       <blue:argument type="node" location="session"
                      name="com/emarson/bluelemon/example"/>
       <blue:argument type="String" value="some text"/>
     </blue:call>
 

However, in most cases it is more convenient to use the equivalent <set node='...' location='...'> syntax:

     <blue:set node="com/emarson/bluelemon/example"
               location="session">
       <blue:argument type="String" value="some text"/>
     </blue:set>
