Method Details

getPrev

default DATA_TYPE getPrev(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index. Previous values are used during an LTM update cycle to process changes in data. During normal operation previous values will be identical to current values.

Specified by:

getPrev in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the value from.

Returns:

the previous value at the index, or null.

getPrevBoolean

default Boolean getPrevBoolean(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as a Boolean. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevBoolean in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous boolean at the index, or null.

getPrevByte

default byte getPrevByte(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as a byte. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevByte in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous boolean at the index, null values are represented by QueryConstants.NULL_BYTE

getPrevChar

default char getPrevChar(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as a char. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevChar in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous char at the index, null values are represented by QueryConstants.NULL_CHAR

getPrevDouble

default double getPrevDouble(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as a double. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevDouble in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous double at the index, null values are represented by QueryConstants.NULL_DOUBLE

getPrevFloat

default float getPrevFloat(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as a float. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevFloat in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous float at the index, null values are represented by QueryConstants.NULL_FLOAT

getPrevInt

default int getPrevInt(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as an int. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevInt in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous int at the index, null values are represented by QueryConstants.NULL_INT

getPrevLong

default long getPrevLong(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as a long. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevLong in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous long at the index, null values are represented by QueryConstants.NULL_LONG

getPrevShort

default short getPrevShort(long elementIndex)

Description copied from interface: ElementSource

Get the previous value at the index as a short. See ElementSource.getPrev(long) for more details.

Specified by:

getPrevShort in interface ElementSource<DATA_TYPE>

Parameters:

elementIndex - the location in index space to get the previous value from.

Returns:

the previous short at the index, null values are represented by QueryConstants.NULL_SHORT

isImmutable

default boolean isImmutable()

Description copied from interface: ColumnSource

Determine if this column source is immutable, meaning that the values at a given index key never change.

Specified by:

isImmutable in interface ColumnSource<DATA_TYPE>

Returns:

true if the values at a given index of the column source never change, false otherwise
