All Implemented Interfaces:

ValidationResultModel

public class ValidationResultModelContainer
extends DefaultValidationResultModel

A validation result model that holds multiple validation results. These can be concatenated or collapsed, see setExpanded(boolean), getCollapsedValidationResult().

TODO: The collapsed validation result shall honor the severity as reported by the expanded validation result.

TODO: The expanded validation result shall be cached.

Constructor Summary

ValidationResultModelContainer(ValidationMessage collapsedMessage)
Constructs a ValidationResultModelContainer using the given validation message for the collapsed state.

Method Summary

void	add(ValidationResultModel resultModel) Adds the given ValidationResultModel to this container's list of children and registers the container to listen for changes in the child.
ValidationResult	getCollapsedValidationResult() Returns the collapsed validation result, i. e. a ValidationResult that just consists of a single ValidationMessage; in this case the collapsed validation message.
ValidationResult	getExpandedValidationResult() Returns the concatenation of all validation results that are held by this container.
boolean	isExpanded() Returns if this container is in expanded or collapsed state.
void	remove(ValidationResultModel resultModel) Removes the given ValidationResultModel from this container's list of children.
void	setExpanded(boolean newExpanded) Sets the container state to expanded or collapsed.
void	setResult(ValidationResult newResult) Rejects to set a new validation result.

Constructor Detail

ValidationResultModelContainer

public ValidationResultModelContainer(ValidationMessage collapsedMessage)

Constructs a ValidationResultModelContainer using the given validation message for the collapsed state. The initial state is expanded.

Parameters:

collapsedMessage - the ValidationMessage used if the container is in collapsed state

Throws:

java.lang.NullPointerException - if the collapsed message is null

Method Detail

isExpanded

public boolean isExpanded()

Returns if this container is in expanded or collapsed state.

Returns:

true if expanded

See Also:

setExpanded(boolean)

setExpanded

public void setExpanded(boolean newExpanded)

Sets the container state to expanded or collapsed.

Parameters:

newExpanded - true to expand, false to collapse

See Also:

isExpanded()

getCollapsedValidationResult

public ValidationResult getCollapsedValidationResult()

Returns the collapsed validation result, i. e. a ValidationResult that just consists of a single ValidationMessage; in this case the collapsed validation message.

TODO: Consider changing the implementation to

 ValidationResult wrapper = new ValidationResult();
 if (getExpandedValidationResult().hasMessages()) {
     wrapper.add(collapsedMessage);
 }
  return wrapper;
 

Returns:

the collapsed validation result

See Also:

getExpandedValidationResult()

getExpandedValidationResult

public ValidationResult getExpandedValidationResult()

Returns the concatenation of all validation results that are held by this container.

Returns:

the concatenation of all validation results that are held by this container

See Also:

getCollapsedValidationResult()

add

public void add(ValidationResultModel resultModel)

Adds the given ValidationResultModel to this container's list of children and registers the container to listen for changes in the child.

Parameters:

resultModel - the ValidationResultModel to be added

See Also:

remove(ValidationResultModel)

remove

public void remove(ValidationResultModel resultModel)

Removes the given ValidationResultModel from this container's list of children. Also unregisters this container to no longer listen for changes in the child.

Parameters:

resultModel - the ValidationResultModel to be removed

See Also:

add(ValidationResultModel)

setResult

public final void setResult(ValidationResult newResult)

Rejects to set a new validation result. The validation result of this container will be computed. Therefore API users are prevented from executing this method; throws an UnsupportedOperationException.

Specified by:

setResult in interface ValidationResultModel

Overrides:

setResult in class DefaultValidationResultModel

Parameters:

newResult - the validation result to be set (ignored)

Throws:

java.lang.UnsupportedOperationException - always
