Method Detail

CanSuggestDataTypeClass

public boolean CanSuggestDataTypeClass()

Always returns false

Specified by:

CanSuggestDataTypeClass in interface IDataType

Returns:

true, if it can

See Also:

IDataType.CanSuggestDataTypeClass()

GetDataTypeClass

public Class<?> GetDataTypeClass()

Returns null

Specified by:

GetDataTypeClass in interface IDataType

Returns:

the run time type

See Also:

IDataType.GetDataTypeClass()

GetDataTypeEnum

public IDataType.DataTypes GetDataTypeEnum()

Returns IDataType.DataTypes.Convertable

Specified by:

GetDataTypeEnum in interface IDataType

Returns:

the data type

See Also:

IDataType.GetDataTypeEnum()

GetStringValue

public String GetStringValue()
                      throws ExecutionSerializationException

if the value is null, an empty string is returned. Otherwise the string representation of the value is returned

Specified by:

GetStringValue in interface IDataType

Returns:

the string representation of the value

Throws:

ExecutionSerializationException - A serialization error occurred

See Also:

IDataType.GetStringValue()

GetValue

public Object GetValue()

this instance is returned

Specified by:

GetValue in interface IDataType

Returns:

the value

See Also:

IDataType.GetValue()

GetConvertedValue

public String GetConvertedValue()

Gets the string representation of the value

Returns:

the string representation

SetConvertedValue

public void SetConvertedValue(String ConvertedValue)

Sets the string representation of the value

Parameters:

ConvertedValue - the string representation of the value

GetConverter

public String GetConverter()

Gets the converter class name

Returns:

the converter class name

SetConverter

public void SetConverter(String Converter)

Sets the converter class name

Parameters:

Converter - the converter class name

SetStringValue

public void SetStringValue(String val)
                    throws ExecutionValidationException,
                           ExecutionSerializationException

If the value is null or an empty string, null is set. Otherwise a call to IDataType.SetValue(Object) is made

Specified by:

SetStringValue in interface IDataType

Parameters:

val - the value to set

Throws:

ExecutionValidationException - A validation error occurred

ExecutionSerializationException - A serialization error occurred

See Also:

IDataType.SetStringValue(java.lang.String)

SetValue

public void SetValue(Object Value)
              throws ExecutionValidationException

If the provided value is null, the string representation of the converted value is set to null. Otherwise, if the value is an instance of DataTypeConvertable, the string representation of the converted value and the converter class name are set to the respective values of the argument. Else if the argument is a string, the string representation of the converted value is set to the argument. Otherwise, if the converter class is set, an instance of that class is initialized and the provided argument is provided to the IObjectConverter.Convert(Object) and the returned string is set as the string representation of the convertable.

Specified by:

SetValue in interface IDataType

Parameters:

Value - the value to set

Throws:

ExecutionValidationException - A validation error occurred

See Also:

IDataType.SetValue(java.lang.Object)
