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.

parse

public static java.util.Date parse(java.lang.String stringValue,
                                   java.util.TimeZone defaultTimeZone,
                                   int 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.
