Method Detail

getCurrentLogical

public int getCurrentLogical()

Specified by:

getCurrentLogical in interface VectorKeySeries

Returns:

the current logical index of the first row of the current key. The next duplicate count rows have the same key.

getCurrentIsAllNull

public boolean getCurrentIsAllNull()

Specified by:

getCurrentIsAllNull in interface VectorKeySeries

Returns:

true when the current key is all nulls.

getCurrentHasAnyNulls

public boolean getCurrentHasAnyNulls()

Specified by:

getCurrentHasAnyNulls in interface VectorKeySeries

Returns:

true when there is at least one null in the current key. Only valid when getCurrentIsAllNull is false. Otherwise, undefined.

getCurrentDuplicateCount

public int getCurrentDuplicateCount()

Specified by:

getCurrentDuplicateCount in interface VectorKeySeries

Returns:

the number of duplicate keys of the current key.

getCurrentHashCode

public int getCurrentHashCode()

Specified by:

getCurrentHashCode in interface VectorKeySeries

Returns:

the hash code of the current key. Only valid when getCurrentIsAllNull is false. Otherwise, undefined.
