LogicalTypeFinite

public LogicalTypeFinite(PluginDefinition plugin)

Method Detail

getMembers

public abstract Set<String> getMembers()

isValid

public boolean isValid(String input)

Description copied from class: LogicalType

Is the supplied String an instance of this logical type?

Specified by:

isValid in class LogicalType

Parameters:

input - String to check (trimmed for Numeric base Types, un-trimmed for String base Type)

Returns:

true iff the supplied String is an instance of this Logical type.

initialize

public boolean initialize(AnalysisConfig analysisConfig)
                   throws FTAPluginException

Description copied from class: LogicalType

Called to perform any initialization.

Overrides:

initialize in class LogicalTypeCode

Parameters:

analysisConfig - The Analysis configuration used for this analysis

Returns:

True if initialization was successful.

Throws:

FTAPluginException - Thrown when the plugin is incorrectly configured.

isRegExpComplete

public boolean isRegExpComplete()

Description copied from class: LogicalType

Is the returned Regular Expression a true and complete representation of the Logical Type. For example, \\d{5} is not for US ZIP codes (e.g. 00000 is not a valid Zip), whereas (?i)(male|female) could be valid for a Gender.

Overrides:

isRegExpComplete in class LogicalType

Returns:

The Java Regular Expression that most closely matches this Logical Type.

isClosed

public boolean isClosed()

Description copied from class: LogicalType

Does the set of members enumerated reflect the entire set. For example any of the ISO sets are reference sets and hence complete, compared to FirstName and LastName where the set provided is of the common names. If isClosed() is true then isValid() false does not imply that the input is not valid just that it is not in the set of 'known' members.

Specified by:

isClosed in class LogicalType

Returns:

A boolean indicating if the set is closed.

getSize

public int getSize()

Get the number of members in this Logical Type.

Returns:

The number of members

getMinLength

public int getMinLength()

Get the minimum length of instances of this Logical Type.

Returns:

The minimum length of instances

getMaxLength

public int getMaxLength()

Get the maximum length of instances of this Logical Type.

Returns:

The maximum length of instances
