Modifier and Type | Method and Description |
---|---|
boolean |
checkUnsortedEncodedKeyComponentsEqual(Double lhs,
Double rhs)
Check if two row value arrays from TimeAndDims keys are equal.
|
int |
compareUnsortedEncodedKeyComponents(Double lhs,
Double rhs)
Compares the row values for this DimensionIndexer's dimension from a TimeAndDims key.
|
Object |
convertUnsortedEncodedKeyComponentToActualArrayOrList(Double key,
boolean asList)
Given a row value array from a TimeAndDims key, as described in the documentation for
compareUnsortedEncodedKeyComponents(), convert the unsorted encoded values to a list or array of actual values.
|
Double |
convertUnsortedEncodedKeyComponentToSortedEncodedKeyComponent(Double key)
Given a row value array from a TimeAndDims key, as described in the documentation for
compareUnsortedEncodedKeyComponents(), convert the unsorted encoded values to an array of sorted encoded values
(i.e., sorted by their corresponding actual values)
|
void |
fillBitmapsFromUnsortedEncodedKeyComponent(Double key,
int rowNum,
MutableBitmap[] bitmapIndexes,
BitmapFactory factory)
Helper function for building bitmap indexes for integer-encoded dimensions.
|
int |
getCardinality()
Get the cardinality of this dimension's values.
|
Double |
getMaxValue()
Get the maximum dimension value seen by this indexer.
|
Double |
getMinValue()
Get the minimum dimension value seen by this indexer.
|
Indexed<Double> |
getSortedIndexedValues()
Returns an indexed structure of this dimension's sorted actual values.
|
int |
getUnsortedEncodedKeyComponentHashCode(Double key)
Given a row value array from a TimeAndDims key, generate a hashcode.
|
Double |
getUnsortedEncodedValueFromSorted(Double sortedIntermediateValue)
Given an encoded value that was ordered by associated actual value, return the equivalent
encoded value ordered by time of ingestion.
|
ColumnValueSelector<?> |
makeColumnValueSelector(TimeAndDimsHolder currEntry,
IncrementalIndex.DimensionDesc desc)
Return an object used to read values from this indexer's column.
|
DimensionSelector |
makeDimensionSelector(DimensionSpec spec,
TimeAndDimsHolder currEntry,
IncrementalIndex.DimensionDesc desc)
Return an object used to read values from this indexer's column as Strings.
|
Double |
processRowValsToUnsortedEncodedKeyComponent(Object dimValues,
boolean reportParseExceptions)
Given a single row value or list of row values (for multi-valued dimensions), update any internal data structures
with the ingested values and return the row values as an array to be used within a TimeAndDims key.
