Constructor Detail

TimeColumnCondition

public TimeColumnCondition(String columnName,
                           ConditionOp op,
                           long value)

Constructor for operations such as less than, equal to, greater than, etc. Uses default sequence condition mode, ColumnCondition.DEFAULT_SEQUENCE_CONDITION_MODE

Parameters:

columnName - Column to check for the condition

op - Operation (<, >=, !=, etc)

value - Time value (in epoch millisecond format) to use in the condition

TimeColumnCondition

public TimeColumnCondition(String column,
                           SequenceConditionMode sequenceConditionMode,
                           ConditionOp op,
                           long value)

Constructor for operations such as less than, equal to, greater than, etc.

Parameters:

column - Column to check for the condition

sequenceConditionMode - Mode for handling sequence data

op - Operation (<, >=, !=, etc)

value - Time value (in epoch millisecond format) to use in the condition
