clearValue

public java.lang.Object clearValue(java.lang.String name)

There is a wrinkle when you replace a variable. Unless you override the value in our collection they will leak and the replaced variable won't have a value! That's of course because variables are used as the key to the value.

Specified by:

clearValue in interface VariableValueManager

Returns:

the existing value (may be null)

clearValue

public java.lang.Object clearValue(Variable v)

Description copied from interface: VariableValueManager

Revert the value of the variable back to it's default.

Specified by:

clearValue in interface VariableValueManager

Returns:

the existing value (may be null)

getPassivatableVariables

public java.lang.String getPassivatableVariables()

Ask the ValueManager to build a package to passivate then do the work with the object stream to get the blob as a fairly compact string to return.

Specified by:

getPassivatableVariables in interface VariableValueManager

getLocalPassivatableVariables

public java.lang.String getLocalPassivatableVariables()

Description copied from interface: VariableValueManager

Used internally by the framework to gather up all variable state that isn't reconstructed by simply resetting from definitions. Doesn't recurse the parent variable managers.

Specified by:

getLocalPassivatableVariables in interface VariableValueManager

activatePassivatedVariables

public void activatePassivatedVariables(java.lang.String passivatedString)

Description copied from interface: VariableValueManager

Used internally by the framework to reinstate the passivation image without causing any ripples in either the validation or notifications.

Specified by:

activatePassivatedVariables in interface VariableValueManager

writeVarsToXML

public boolean writeVarsToXML(Document xmlDoc,
                              Element parent,
                              boolean local)

Description copied from interface: VariableValueManager

Writes XML elements for all variables in this variable manager and appends them to the given parent node. Used internally by the framework to gather up all variable state that isn't reconstructed by simply resetting from definitions.

Specified by:

writeVarsToXML in interface VariableValueManager

Parameters:

xmlDoc - the XML document in which the variables should be passivated

parent - the enclosing XML node where new nodes will be appended

local - if true do not recurse the parent variable managers

Returns:

true if variable nodes were appended to the parent node.

See Also:

VariableValueManager.readVarsFromXML(Element)

readVarsFromXML

public void readVarsFromXML(Element varsElem)

Description copied from interface: VariableValueManager

Reads all the variables from the XML element and sets them into this variable manager. Used internally by the framework to reinstate the passivation image without causing any ripples in either the validation or notifications.

Specified by:

readVarsFromXML in interface VariableValueManager

Parameters:

varsElem - an XML node containing the passivated variables

VariableValueManager.writeVarsToXML(Document, Element, boolean)
