Field Detail

FM_APPEND

static final java.lang.String FM_APPEND

FILL-MODE constant. FILLing will add new records on top of the ones already existing in the table. No record comparisons are executed, meaning that duplicate records may be obtained.

Constant Field Values

FM_EMPTY

static final java.lang.String FM_EMPTY

FILL-MODE constant. The FILL operations start with an empty table.

See Also:

Constant Field Values

FM_MERGE

static final java.lang.String FM_MERGE

FILL-MODE constant. Merge new records with existing ones. Records are not refreshed. This is the default.

Constant Field Values

FM_NOFILL

static final java.lang.String FM_NOFILL

FILL-MODE constant. Does not perform the FILL operation on the table.

See Also:

Constant Field Values

FM_REPLACE

static final java.lang.String FM_REPLACE

FILL-MODE constant. Most time consuming mode. Refreshes the old records.

Method Detail

fill

logical fill()

Fills a DataSet object, recursively, based on its defined data sources, data relations, and queries. When invoked on one of its member Buffer objects a partial fill is performed, by starting at the respective level.

Returns:

true if operation is successful.

fillMode

character fillMode()

Obtain the mode in which the DataSet.fill() method fills a DataSet member buffer. The default mode is MERGE.

Returns:

the fill mode for this buffer.

fillMode

void fillMode(java.lang.String mode)

Configures the mode in which the DataSet.fill() method fills a DataSet member buffer. The allowed modes are: APPEND, EMPTY, MERGE, NO-FILL, and REPLACE.

Parameters:

mode - the new fill mode for this buffer.

fillMode

void fillMode(Text mode)

Configures the mode in which the DataSet.fill() method fills a DataSet member buffer. The allowed modes are: APPEND, EMPTY, MERGE, NO-FILL, and REPLACE.

Parameters:

mode - the new fill mode for this buffer.
