Package se.litsec.opensaml.common.validation

Class AbstractObjectValidator<T extends XMLObject>

java.lang.Object

se.litsec.opensaml.common.validation.AbstractObjectValidator<T>

All Implemented Interfaces:

ObjectValidator<T>

Direct Known Subclasses:

AbstractSignableObjectValidator

public abstract class AbstractObjectValidator<T extends XMLObject>
extends Object
implements ObjectValidator<T>

Abstract base class for ObjectValidator.

Supports the following ValidationContext static parameters:

• CoreValidatorParameters.STRICT_VALIDATION: Optional. If not supplied, defaults to 'false'. Tells whether strict validation should be performed.
• CoreValidatorParameters.ALLOWED_CLOCK_SKEW: Optional. Gives the number of milliseconds that is the maximum allowed clock skew. If not given DEFAULT_ALLOWED_CLOCK_SKEW is used.
• CoreValidatorParameters.MAX_AGE_MESSAGE: Optional. Gives the maximum age (difference between issuance time and the validation time). If not given, the DEFAULT_MAX_AGE_RECEIVED_MESSAGE is used.

Modifier and Type	Method	Description
static long	getAllowedClockSkew(ValidationContext context)	Returns the number of milliseconds that is the maximum allowed clock skew that we accept when comparing time stamps.

Method Detail

isStrictValidation

public static boolean isStrictValidation(ValidationContext context)

Tells whether this validator runs in "strict" mode. This value is read from the static validation context parameter CoreValidatorParameters.STRICT_VALIDATION. If this parameter is not available false is returned.

Parameters:

context - the validation context

Returns:

true for strict mode, and false otherwise

getAllowedClockSkew

public static long getAllowedClockSkew(ValidationContext context)

Returns the number of milliseconds that is the maximum allowed clock skew that we accept when comparing time stamps. The value is read from the static validation context parameter CoreValidatorParameters.ALLOWED_CLOCK_SKEW. If this parameter is not available, DEFAULT_ALLOWED_CLOCK_SKEW is used.

Parameters:

context - the validation context

Returns:

the number of milliseconds that is the maximum allowed clock skew

getMaxAgeReceivedMessage

public static long getMaxAgeReceivedMessage(ValidationContext context)

Returns the number of milliseconds that a received message (or element) is allowed to less than the current time. The value is read from the static validation context parameter CoreValidatorParameters.MAX_AGE_MESSAGE. If this parameter is not available, DEFAULT_MAX_AGE_RECEIVED_MESSAGE is used.

Parameters:

context - the validation context

Returns:

the maximum number of milliseconds that may have elapsed since the issuance of a message and validation of it

getReceiveInstant

public static long getReceiveInstant(ValidationContext context)

Returns the timestamp (milliseconds since epoch) for when the message being validated was received. The value is read from CoreValidatorParameters.RECEIVE_INSTANT. If the parameter is not available the current time is returned.

Parameters:

context - the validation context.

Returns:

the timestamp for when the message being validated was received
