Parameters:

pCellEditor - the cell editor

BigDecimalDataType

public BigDecimalDataType(int pPrecision,
                          int pScale,
                          ICellEditor pCellEditor)

Method Detail

getTypeIdentifier

public int getTypeIdentifier()

Gets the data type identifier.

Returns:

a unique type identifier

getTypeClass

public Class getTypeClass()

Returns the class of the Object's handled by IDataType.

Returns:

the class of the Object's handled by IDataType.

convertToString

public String convertToString(Object pObject)

Converts the oObject into a String which represents the Object.

Parameters:

pObject - the source Object to convert

Returns:

the String representation of the source Object

convertToTypeClass

public Object convertToTypeClass(Object pObject)
                          throws ModelException

Parameters:

pObject - the source Object to convert

Returns:

the converted Object that is instance of the class which is handled by IDataType.

Throws:

ModelException - if the class/type of oObject is not supported
