public String getTableName()

Gets the name of the table the column exists in. Null is returned if the table name is not specified.

Returns:

name of table column exists in.

getCompleteToken

public String getCompleteToken()

setCompleteToken

public void setCompleteToken(String token)

setFieldDescriptor

public ColumnToken setFieldDescriptor(FieldDescriptorRow pFDRow)
                               throws CMException

Sets the FieldDescriptor for this database column referenced by this token. This can be used to adjust or change the FD associated with this columnToken. For example, when performing a SQL such as: select ..... where concat(a,b) = ? we don't know what to use for the column token of the concat(a,b) if if a or b is used the desired external name, length, etc will not be appropriate since we are concating 2 fields... This method will allow a DerivedFieldDescriptor to be created and set for this column...
