Constructor Detail

LengthValidationRule

public LengthValidationRule()
Method Detail

setExactExpr

public void setExactExpr(org.outerj.expression.Expression exactExpr)

setMinExpr

public void setMinExpr(org.outerj.expression.Expression minExpr)

setMaxExpr

public void setMaxExpr(org.outerj.expression.Expression maxExpr)

validate

public ValidationError validate(Object value,
                                org.outerj.expression.ExpressionContext expressionContext)
Parameters:
value - a value of a class supported by the ValidationRule implementation
expressionContext - many validation rules use the xReporter expression interpreter, the expressionContext allows to resolve variables used in these expressions.

supportsType

public boolean supportsType(Class clazz,
                            boolean arrayType)
Description copied from interface: ValidationRule
Returns true if this ValidationRule supports validating objects of the same class as the one specified. If the flag 'arrayType' is true, this method will return true if this validation rule can validate arrays of these objects (i.e. the object passed to the validate method will then be an array).
