BooleanCondition: used for creating compound conditions, such as AND(ConditionA, ConditionB, …)
As a BooleanCondition is a condition, these can be chained together, like NOT(OR(AND(…),AND(…)))
outputColumnName
The output column name after the operation has been applied
return the output column name
columnName
The output column names This will often be the same as the input
return the output column names
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
conditionSequence
Condition on arbitrary input
param sequence the sequence to do a condition on
return true if the condition for the sequence is met false otherwise
transform
Get the output schema for this transformation, given an input schema
param inputSchema
AND
And of all the given conditions
param conditions the conditions to and
return a joint and of all these conditions
OR
Or of all the given conditions
param conditions the conditions to or
return a joint and of all these conditions
NOT
Not of the given condition
param condition the conditions to and
return a joint and of all these condition
XOR
And of all the given conditions
param first the first condition
param second the second condition for xor
return the xor of these 2 conditions
SequenceConditionMode
For certain single-column conditions: how should we apply these to sequences?
And: Condition applies to sequence only if it applies to ALL time steps
Or: Condition applies to sequence if it applies to ANY time steps
NoSequencMode: Condition cannot be applied to sequences at all (error condition)

columnCondition
Returns whether the given element meets the condition set by this operation
param writable the element to test
return true if the condition is met false otherwise
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
CategoricalColumnCondition
columnCondition
Constructor for conditions equal or not equal. Uses default sequence condition mode, {- link BaseColumnCondition#DEFAULT_SEQUENCE_CONDITION_MODE}
param columnName Column to check for the condition
param op Operation (== or != only)
param value Value to use in the condition
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
DoubleColumnCondition
columnCondition
Constructor for operations such as less than, equal to, greater than, etc. Uses default sequence condition mode, {- link BaseColumnCondition#DEFAULT_SEQUENCE_CONDITION_MODE}
param columnName Column to check for the condition
param op Operation (<, >=, !=, etc)
param value Value to use in the condition
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
InfiniteColumnCondition
A column condition that simply checks whether a floating point value is infinite
columnCondition
param columnName Column check for the condition
IntegerColumnCondition
columnCondition
Constructor for operations such as less than, equal to, greater than, etc. Uses default sequence condition mode, {- link BaseColumnCondition#DEFAULT_SEQUENCE_CONDITION_MODE}
param columnName Column to check for the condition
param op Operation (<, >=, !=, etc)
param value Value to use in the condition
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
InvalidValueColumnCondition
A Condition that applies to a single column. Whenever the specified value is invalid according to the schema, the condition applies.
For example, if a Writable contains String values in an Integer column (and these cannot be parsed to an integer), then the condition would return true, as these values are invalid according to the schema.
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
LongColumnCondition
columnCondition
Constructor for operations such as less than, equal to, greater than, etc. Uses default sequence condition mode, {- link BaseColumnCondition#DEFAULT_SEQUENCE_CONDITION_MODE}
param columnName Column to check for the condition
param op Operation (<, >=, !=, etc)
param value Value to use in the condition
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
NaNColumnCondition
A column condition that simply checks whether a floating point value is NaN
columnCondition
param columnName Name of the column to check the condition for
NullWritableColumnCondition
Condition that applies to the values in any column. Specifically, condition is true if the Writable value is a NullWritable, and false for any other value
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
StringColumnCondition
columnCondition
Constructor for conditions equal or not equal Uses default sequence condition mode, {- link BaseColumnCondition#DEFAULT_SEQUENCE_CONDITION_MODE}
param columnName Column to check for the condition
param op Operation (== or != only)
param value Value to use in the condition
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
TimeColumnCondition
Condition that applies to the values
columnCondition
Constructor for operations such as less than, equal to, greater than, etc. Uses default sequence condition mode, {- link BaseColumnCondition#DEFAULT_SEQUENCE_CONDITION_MODE}
param columnName Column to check for the condition
param op Operation (<, >=, !=, etc)
param value Time value (in epoch millisecond format) to use in the condition
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise

SequenceLengthCondition
A condition on sequence lengths
StringRegexColumnCondition
Condition that applies to the values in a String column, using a provided regex. Condition return true if the String matches the regex, or false otherwise
Note: Uses Writable.toString(), hence can potentially be applied to non-String columns
condition
Condition on arbitrary input
param input the input to return the condition for
return true if the condition is met false otherwise
