Method Summary

Modifier and Type	Method and Description
logical	acceptChanges() Accepts changes to the data in target object (a temp-table or all temp-tables in a DataSet).
logical	getChanges(handle original) Loads the empty target (DataSet or TempTable) object with changed rows from original (source) object.
logical	getChanges(handle original, boolean parentMode) Loads the empty target (DataSet or TempTable) object with changed rows from original (source) object.
logical	getChanges(handle original, logical parentMode) Loads the empty target (DataSet or TempTable) object with changed rows from original (source) object.
logical	mergeChanges(handle original) Merges the changed rows of all temp-tables or a single temp-table in a source DataSet object loaded with the GET-CHANGES() method into the corresponding rows of all temp-tables or a single temp-table (respectively) in the original (target) DataSet object.
logical	mergeChanges(handle original, boolean allCopyMode) Merges the changed rows of all temp-tables or a single temp-table in a source DataSet object loaded with the GET-CHANGES() method into the corresponding rows of all temp-tables or a single temp-table (respectively) in the original (target) DataSet object.
logical	mergeChanges(handle original, logical allCopyMode) Merges the changed rows of all temp-tables or a single temp-table in a source DataSet object loaded with the GET-CHANGES() method into the corresponding rows of all temp-tables or a single temp-table (respectively) in the original (target) DataSet object.
logical	rejectChanges() Rejects changes to the data in target object (a temp-table or all temp-tables in a DataSet).

Method Detail

getChanges

logical getChanges(handle original)

Loads the empty target (DataSet or TempTable) object with changed rows from original (source) object.

Parameters:

original - Handle to original object (DataSet or TempTable) that contains the changed rows to load into the target object.

Returns:

true if operation is successful.

getChanges

logical getChanges(handle original,
                   logical parentMode)

Loads the empty target (DataSet or TempTable) object with changed rows from original (source) object.

Parameters:

original - Handle to original object (DataSet or TempTable) that contains the changed rows to load into the target object.

parentMode - When TRUE the target gets the changed parent rows of each changed child row.

Returns:

true if operation is successful.

getChanges

logical getChanges(handle original,
                   boolean parentMode)

Loads the empty target (DataSet or TempTable) object with changed rows from original (source) object.

Parameters:

original - Handle to original object (DataSet or TempTable) that contains the changed rows to load into the target object.

parentMode - When TRUE the target gets the changed parent rows of each changed child row.

Returns:

true if operation is successful.

mergeChanges

logical mergeChanges(handle original)

Merges the changed rows of all temp-tables or a single temp-table in a source DataSet object loaded with the GET-CHANGES() method into the corresponding rows of all temp-tables or a single temp-table (respectively) in the original (target) DataSet object.

Parameters:

original - A handle to the original (target) DataSet object or the buffer object of a single target DataSet temp-table to merge with the changed rows from the source object.

Returns:

true if operation is successful.

mergeChanges

logical mergeChanges(handle original,
                     logical allCopyMode)

Merges the changed rows of all temp-tables or a single temp-table in a source DataSet object loaded with the GET-CHANGES() method into the corresponding rows of all temp-tables or a single temp-table (respectively) in the original (target) DataSet object.

Parameters:

original - A handle to the original (target) DataSet object or the buffer object of a single target DataSet temp-table to merge with the changed rows from the source object.

allCopyMode - Use TRUE to indicates that all rows of the source after-image table must be merged.

Returns:

true if operation is successful.

mergeChanges

logical mergeChanges(handle original,
                     boolean allCopyMode)

Merges the changed rows of all temp-tables or a single temp-table in a source DataSet object loaded with the GET-CHANGES() method into the corresponding rows of all temp-tables or a single temp-table (respectively) in the original (target) DataSet object.

Parameters:

original - A handle to the original (target) DataSet object or the buffer object of a single target DataSet temp-table to merge with the changed rows from the source object.

allCopyMode - Use TRUE to indicates that all rows of the source after-image table must be merged.

Returns:

true if operation is successful.

acceptChanges

logical acceptChanges()

Accepts changes to the data in target object (a temp-table or all temp-tables in a DataSet).

Returns:

true if operation is successful.

rejectChanges

logical rejectChanges()

Rejects changes to the data in target object (a temp-table or all temp-tables in a DataSet).

Returns:

true if operation is successful.
