Compares this stepfield to the specified object. | | String | getAlias()
Gets the alias for the associated field. | | String | getFieldName()
Gets the name of the associated field (without prefix). | | Step | getStep()
Gets the step associated with this fieldstep. | | int | getType()
Gets the type of the associated field. | | public int | hashCode()
| | public String | toString()
Returns a string representation of this StepField. |
| equals | | public boolean equals(Object obj)(Code) | | Compares this stepfield to the specified object. The result is
true if and only if the argument is a non-null
StepField object associated with the same field, using the same alias.

|
| hashCode | | public int hashCode()(Code) | | |
| toString | | public String toString()(Code) | | Returns a string representation of this StepField.
The string representation has the form
"StepField(step:<step>, fieldname:<fieldname>, alias:<alias>)"
where
- <step> is the step alias returned by
getStep().getAlias() or,
when the step alias is null, the step tablename
returned by getStep().getTableName().
- <fieldname> is the fieldname returned by

- <alias> is the alias returned by
StepField.getAlias getAlias()
A string representation of this StepField. |
