Method Detail

findAnnotationValidator

public static final AnnotationValidator findAnnotationValidator(javax.faces.context.FacesContext context)

This method attempts to locate an AnnotationValidator, does NOT initiate one. First it checks if it can be found in the JsfConfigurationDeclarative instance. Currently it checks if it is bound in the ServletContext.

Parameters:

context - The facescontext to check

Returns:

AnnotationValidator instance that is bound somewhere (thru configuration).

Throws:

JavalidException - if the validator could not be found

addExpression

public static final java.lang.String addExpression(java.lang.String expression)

Makes an expression for given text. If it is not already one. Adds #{} around it. Checks for #{} and ${}.

Parameters:

expression - The text to make an expression from

Returns:

Expression

removeExpression

public static final java.lang.String removeExpression(java.lang.String expression)

For given expression string strips the jsf tags, e.g. #{myValue.whatever} strips off #{ and }. Spaces are removed as well (after stripping)

Parameters:

expression - The expression to strip off #{}, or ${}

Returns:

The stripped expression, if expression was null, returns null as well.

isExpression

public static final boolean isExpression(java.lang.String value)

Checks if given value starts with #{ or ${ and ends with }, like a jsf expression. First trims the value of spaces, then performs the check, also the length must be > 3 (thus actually contain something between the braces).

Parameters:

value - The value to check

Returns:

True if it conforms a jsf expression, false otherwise.

containsExpression

public static final boolean containsExpression(java.lang.String value)

Returns true if given value contains an expression (somewhere in the text). E.g:#{bean} or test#{something} would both return true. Checks on #{} and ${}. False if no expression was found.

Parameters:

value - The value to check

Returns:

True if found, false otherwise.

newJsfFacade
