public final class BooleanLogFieldSyntax
extends LogFieldSyntax<java.lang.Boolean>

This class defines a log field syntax for Boolean values. This syntax does not support redacting or tokenizing individual components within the values.

NOTE: This class, and other classes within the com.unboundid.ldap.sdk.unboundidds package structure, are only supported for use against Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 server products. These classes provide support for proprietary functionality or for external specifications that are not considered stable or mature enough to be guaranteed to work in an interoperable way with other types of LDAP servers.

                                ByteStringBuffer buffer)

Appends a tokenized representation of the provided value to the given buffer.

The resulting token will protect the provided value by representing it in a way that makes it at infeasible to determine what the original value was. However, tokenizing the same value with the same pepper should consistently yield the same token value, so that it will be possible to identify the same value across multiple log messages.

Specified by:

tokenizeEntireValue in class LogFieldSyntax<java.lang.Boolean>

Parameters:

value - The value for which to generate the token. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token. It must not be null and should not be empty.

buffer - The buffer to which the tokenized representation should be appended. It must not be null.

fieldValue - The value to use for the field. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token. It must not be null and should not be empty.

buffer - The buffer to which the sanitized log field should be appended. It must not be null.

                                                          JSONBuffer buffer)

Appends a completely tokenized representation of the provided value (without a field name, as might be suitable for a value included in a JSON array) for a JSON-formatted log message to the given buffer.

Specified by:

logCompletelyTokenizedValueToJSONFormattedLog in class LogFieldSyntax<java.lang.Boolean>

Parameters:

value - The value to be appended to the buffer in tokenized form. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token. It must not be null and should not be empty.

buffer - The buffer to which the tokenized value should be appended. It must not be null.

supportsTokenizedComponents

public boolean supportsTokenizedComponents()

Indicates whether this syntax supports tokenizing individual components of the entire value.

Specified by:

supportsTokenizedComponents in class LogFieldSyntax<java.lang.Boolean>

Returns:

true if this syntax supports tokenizing individual components of the entire value, or false if not.

valueWithTokenizedComponentsConformsToSyntax

public boolean valueWithTokenizedComponentsConformsToSyntax()

Indicates whether values with one or more tokenized components still conform to this syntax.

Specified by:

valueWithTokenizedComponentsConformsToSyntax in class LogFieldSyntax<java.lang.Boolean>

Returns:

true if values with one or more tokenized components still conform to this syntax.

Appends a representation of the specified field (both field name and value) with tokenized value components for a text-formatted log message to the given buffer. If this syntax does not support tokenizing components within a value, then it should tokenize the entire value.

Parameters:

fieldName - The name for the field. It must not be null.

fieldValue - The value to use for the field. It must not be null.

pepper - A pepper used to provide brute-force protection for the resulting token. The pepper value should be kept secret so that it is not available to unauthorized users who might be able to view log information, although the same pepper value should be consistently provided when tokenizing values so that the same value will consistently yield the same token. It must not be null and should not be empty.
