      org.apache.cocoon.woody.datatype.validationruleimpl.RangeValidationRule

All Implemented Interfaces:

ValidationRule

public class RangeValidationRule
extends AbstractValidationRule

Checks numeric ranges. Works for Integer, Long, BigDecimal, Float, Double, and Date values. Numbers are converted to the BigDecimal before comparing.

This validation rule can perform 3 different checks:

Method Detail

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).
