Method Detail

isStateless

public boolean isStateless()

component is stateless

Overrides:

isStateless in class ERXNonSynchronizingComponent

valueForIntBinding

public int valueForIntBinding(String binding,
                              int defaultValue)

Deprecated. use intValueForBinding() instead

Resolves a given binding as a int value. Useful for image sizes and the like.

Parameters:

binding - binding to be resolved as a int value.

defaultValue - default int value to be used if the binding is not bound.

Returns:

result of evaluating binding as a int.

valueForBooleanBinding

public boolean valueForBooleanBinding(String binding)

Deprecated. use booleanValueForBinding() instead

Resolves a given binding as a boolean value. Defaults to false.

Parameters:

binding - binding to be resolved as a boolean value.

Returns:

result of evaluating binding as a boolean.

valueForBooleanBinding

public boolean valueForBooleanBinding(String binding,
                                      boolean defaultValue)

Deprecated. use booleanValueForBinding() instead

Resolves a given binding as a boolean value.

Overrides:

valueForBooleanBinding in class WOComponent

Parameters:

binding - binding to be resolved as a boolean value.

defaultValue - default boolean value to be used if the binding is not bound.

Returns:

result of evaluating binding as a boolean.

valueForBooleanBinding

public boolean valueForBooleanBinding(String binding,
                                      ERXUtilities.BooleanOperation defaultValue)

Deprecated. use booleanValueForBinding() instead

Resolves a given binding as a boolean value with the option of specifing a boolean operator as the default value.

Parameters:

binding - name of the component binding.

defaultValue - boolean operator to be evaluated if the binding is not present.

Returns:

result of evaluating binding as a boolean.

valueForObjectBinding

public Object valueForObjectBinding(String binding)

Deprecated. use objectValueForBinding() instead

Resolves a given binding as an object in the normal fashion of calling valueForBinding. This has the one advantage of being able to resolve the resulting object as a {link ERXUtilities$Operation} if it is an Operation and then returning the result as the evaluation of that operation.

Parameters:

binding - name of the component binding.

Returns:

the object for the given binding and in the case that it is an instance of an Operation the value of that operation.

valueForObjectBinding

public Object valueForObjectBinding(String binding,
                                    Object defaultValue)

Deprecated. use objectValueForBinding() instead

Resolves a given binding as an object in the normal fashion of calling valueForBinding. This has the one advantage of being able to resolve the resulting object as a {link ERXUtilities$Operation} if it is an Operation and then returning the result as the evaluation of that operation.

Parameters:

binding - name of the component binding.

defaultValue - value to be used if valueForBinding returns null.

Returns:

the object for the given binding and in the case that it is an instance of an Operation the value of that operation.

reset

public void reset()

Overrides:

reset in class ERXComponent
