dynamicBindings

public NSMutableDictionary dynamicBindings()

synchronizesVariablesWithBindings

public boolean synchronizesVariablesWithBindings()

component does not synchronize variables

isStateless

public boolean isStateless()

component is not stateless

intValueForBinding

public int intValueForBinding(String binding,
                              int defaultValue)

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.

booleanValueForBinding

public boolean booleanValueForBinding(String binding)

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.

booleanValueForBinding

public boolean booleanValueForBinding(String binding,
                                      boolean defaultValue)

Resolves a given binding as a boolean value.

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.

booleanValueForBinding

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

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.

objectValueForBinding

public Object objectValueForBinding(String binding)

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.

objectValueForBinding

public Object objectValueForBinding(String binding,
                                    Object defaultValue)

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.

stringValueForBinding

public String stringValueForBinding(String binding)

Retrieves a given binding and if it is not null then returns toString called on the bound object.

Parameters:

binding - to be resolved

Returns:

resolved binding in string format

stringValueForBinding

public String stringValueForBinding(String binding,
                                    String defaultValue)

Retrieves a given binding and if it is not null then returns toString called on the bound object.

Parameters:

binding - to be resolved

defaultValue - value to be used if valueForBinding returns null.

Returns:

resolved binding in string format

localizer

public ERXLocalizer localizer()
