Class DmcTypeBoolean

java.lang.Object

org.dmd.dmc.DmcAttribute<Boolean>

org.dmd.dmc.types.DmcTypeBoolean

All Implemented Interfaces:

Serializable, Cloneable, Comparable<String>

Direct Known Subclasses:

DmcTypeBooleanMV, DmcTypeBooleanSET, DmcTypeBooleanSV

public abstract class DmcTypeBoolean
extends DmcAttribute<Boolean>
implements Serializable

The DmcBoolean type is meant to store Boolean values. The set/add interfaces will accept Boolean objects, String objects with "true" or "false", regardless of case of the characters, or Integer objects where 0 maps to false and everything else to true.

Method Detail

typeCheck

public Boolean typeCheck(Object value)
                  throws DmcValueException

Description copied from class: DmcAttribute

Derived classes must overload this method to determine if the value passed in conforms with their type criteria.

Specified by:

typeCheck in class DmcAttribute<Boolean>

Parameters:

value - the value to be checked

Returns:

a value holder

Throws:

DmcValueException - if the value is incorrect

cloneValue

public Boolean cloneValue(Boolean original)

Description copied from class: DmcAttribute

This method must be overridden to clone whatever value is stored in this attribute. The concept of clone constructors was considered, but this doesn't work for enumerated values.

Specified by:

cloneValue in class DmcAttribute<Boolean>

Parameters:

original - the original value

Returns:

A clone of the value.

serializeValue

public void serializeValue(DmcOutputStreamIF dos,
                           Boolean value)
                    throws Exception

Write a Boolean.

Specified by:

serializeValue in class DmcAttribute<Boolean>

Parameters:

dos - The output stream.

value - The value to be serialized.

Throws:

Exception

deserializeValue

public Boolean deserializeValue(DmcInputStreamIF dis)
                         throws Exception

Read a Boolean.

Specified by:

deserializeValue in class DmcAttribute<Boolean>

Parameters:

dis - the input stream.

Returns:

A value read from the input stream.

Throws:

Exception
