boolean	isUpdateable() Finds out whether the attribute is updateable or is for display only.
boolean	processNewInputValue(java.lang.Object value) Prepare the binding for being able to accept a new value
void	setInputValue(java.lang.Object inputVal) Update the attribute value associated with this binding.

Method Detail

getInputValue

java.lang.Object getInputValue()

Return the value that should be rendered on a view for the attribute associated with this binding.

Specified by:

getInputValue in interface AttributeBinding

Returns:

The attribute value.

setInputValue

void setInputValue(java.lang.Object inputVal)

Update the attribute value associated with this binding. If there are exceptions while updating this attribute, these exceptions should be accessible via getErrors()

Specified by:

setInputValue in interface AttributeBinding

Parameters:

inputVal - The new attribute value.

See Also:

AttributeBinding.getErrors()

validateInputValue

java.lang.Object validateInputValue(java.lang.Object inputVal)

validate the given value with validations applied at the binding level (if any.) Return value of null means the validation succeeded. In case of failed validation, the return value should be an Exception object. Some attribute bindings may want to generate 'warning' type messages from this method. To account for those, the return type is not an Exception object itself.

getLabel

java.lang.String getLabel()

Return the display label or prompt for the attribute represented by this binding.

Specified by:

getLabel in interface AttributeBinding

Returns:

The display label or prompt string.

isUpdateable

boolean isUpdateable()

Description copied from interface: AttributeBinding

Finds out whether the attribute is updateable or is for display only.

Specified by:

isUpdateable in interface AttributeBinding

Returns:

True if the attribute is updateable, false otherwise.

getErrors

java.util.List getErrors()

Return a list of errors that were raised during setInputValue()

Specified by:

getErrors in interface AttributeBinding

Returns:

A list of Throwable that were raised during setInputValue(). It returns null if there is no error occurred.

See Also:

AttributeBinding.setInputValue(Object)

processNewInputValue

boolean processNewInputValue(java.lang.Object value)

Prepare the binding for being able to accept a new value
