Constructor Details

CategoricalIDInfo

public CategoricalIDInfo(CategoricalInfo info,
 int id)

Constructs a categorical id info copying the information from the supplied info, with the specified id.

Parameters:

info - The info to copy.

id - The id number to use.

Method Details

deserializeFromProto

public static CategoricalIDInfo deserializeFromProto(int version,
 String className,
 com.google.protobuf.Any message)
                                              throws com.google.protobuf.InvalidProtocolBufferException

Deserialization factory.

Parameters:

version - The serialized object version.

className - The class name.

message - The serialized data.

Returns:

The deserialized object.

Throws:

com.google.protobuf.InvalidProtocolBufferException - If the protobuf could not be parsed from the message.

getID

public int getID()

Description copied from interface: VariableIDInfo

The id number associated with this variable.

Ids are non-negative integers.

Specified by:

getID in interface VariableIDInfo

Returns:

The id number.

generateRealInfo

public RealIDInfo generateRealInfo()

Generates a RealIDInfo that matches this CategoricalInfo and also contains an id number.

Overrides:

generateRealInfo in class CategoricalInfo

Returns:

A RealInfo representing the data in this CategoricalInfo.

copy

public CategoricalIDInfo copy()

Description copied from interface: VariableInfo

Returns a copy of this variable info.

Specified by:

copy in interface VariableInfo

Overrides:

copy in class CategoricalInfo

Returns:

A copy.

makeIDInfo

public CategoricalIDInfo makeIDInfo(int id)

Description copied from interface: VariableInfo

Generates a VariableIDInfo subclass which represents the same feature.

Specified by:

makeIDInfo in interface VariableInfo

Overrides:

makeIDInfo in class CategoricalInfo

Parameters:

id - The id number.

Returns:

A VariableInfo with the same information, plus the id.

rename

public CategoricalIDInfo rename(String newName)

Description copied from interface: VariableInfo

Rename generates a fresh VariableInfo with the new name. The name forms part of the hashcode so it's immutable in the object.

Specified by:

rename in interface VariableInfo

Overrides:

rename in class CategoricalInfo

Parameters:

newName - The new name.

Returns:

A VariableInfo subclass with the new name.

toString

public String toString()

Overrides:

toString in class CategoricalInfo

equals

public boolean equals(Object o)

Overrides:

equals in class CategoricalInfo

hashCode

public int hashCode()

Overrides:

hashCode in class CategoricalInfo
