      org.dhmp.util.xml.validator.NumberValidator

public class NumberValidator

extends Validator

Validates several number related data types. Data types decimal and integer are converted to java BigDecimal. Data types double, float, long and int are converted to corresponding java objects. The conversion is locale sensitive and decimal and group separator interpretation depends on current SchemaCollection's locale.

Constructor Detail

NumberValidator

public NumberValidator(java.util.Locale locale,
                       int type)

Creates a new instance of DecimalValidator

Parameters:

locale - SchemaCollection's locale.

type - number data type which this validator will represent.

Method Detail

validate

public java.lang.Object validate(java.lang.String name,
                                 java.lang.Object value,
                                 HierarchicalMap constraints,
                                 Schema schema,
                                 HierarchicalMap messages,
                                 int replace)

Description copied from class: Validator

Returns true if the validation is successfull. A concreate class can be extended to validate specific data type. It also can replace the value with java object for corresponding XSD data type.

Specified by:

validate in class Validator

Parameters:

name - name of schema component beeing validated.

value - value that is beeing validated.

constraints - HierarchicalMap containing constraints.

schema - reference to Schema which is validating the current value.

messages - StringBuffer where the error messages are appended.

replace - true if value should be replaced by corresponding java Object.

Returns:

true if value contains an valid data type.

compareTo

public int compareTo(java.lang.Object o1,
                     java.lang.Object o2)

Description copied from class: Validator

Abstract method for comparing two valid objects used for boundry check.

Specified by:

compareTo in class Validator

Parameters:

o1 - first object.

o2 - second object.

Returns:

0 - if two objects are equivalent; < 0 if o1 is less than o2; >0 if o1 is greater than o2.

newValue

public java.lang.Object newValue(java.lang.Object value)

Description copied from class: Validator

Creates a java instance of corresponding object depending on data type this Validator is written for.

Specified by:

newValue in class Validator

Parameters:

value - value to be converted to java object depending on data type.

Returns:

java object of corresponding data type.
