Method Summary

java.util.List	getErrors() Return a list of errors that were raised during setInputValue()
java.lang.Object	getInputValue() Return the value that should be rendered on a view for the attribute associated with this binding.
java.lang.String	getLabel() Return the display label or prompt for the attribute represented by this binding.
boolean	isUpdateable()
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.
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.

Method Detail

getInputValue

public java.lang.Object getInputValue()

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

setInputValue

public 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()

validateInputValue

public 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

public java.lang.String getLabel()

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

isUpdateable

public boolean isUpdateable()

getErrors

public java.util.List getErrors()

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

processNewInputValue

public boolean processNewInputValue(java.lang.Object value)

Prepare the binding for being able to accept a new value
