Conditions

BooleanCondition

[source]
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

1
public String outputColumnName()
Copied!
The output column name after the operation has been applied
    return the output column name

columnName

1
public String columnName()
Copied!
The output column names This will often be the same as the input
    return the output column names
condition
1
public boolean condition(Object input)
Copied!
Condition on arbitrary input
    param input the input to return the condition for
    return true if the condition is met false otherwise
conditionSequence
1
public boolean conditionSequence(Object sequence)
Copied!
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
1
public Schema transform(Schema inputSchema)
Copied!
Get the output schema for this transformation, given an input schema
    param inputSchema

AND

1
public static Condition AND(Condition... conditions)
Copied!
And of all the given conditions
    param conditions the conditions to and
    return a joint and of all these conditions

OR

1
public static Condition OR(Condition... conditions)
Copied!
Or of all the given conditions
    param conditions the conditions to or
    return a joint and of all these conditions

NOT

1
public static Condition NOT(Condition condition)
Copied!
Not of the given condition
    param condition the conditions to and
    return a joint and of all these condition

XOR

1
public static Condition XOR(Condition first, Condition second)
Copied!
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

[source]
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
1
public boolean columnCondition(Writable writable)
Copied!
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
1
public boolean condition(Object input)
Copied!
Condition on arbitrary input
    param input the input to return the condition for

CategoricalColumnCondition

[source]
columnCondition
1
public boolean columnCondition(Writable writable)
Copied!
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
1
public boolean condition(Object input)
Copied!
Condition on arbitrary input
    param input the input to return the condition for
    return true if the condition is met false otherwise

DoubleColumnCondition

[source]
columnCondition
1
public boolean columnCondition(Writable writable)
Copied!
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
1
public boolean condition(Object input)
Copied!
Condition on arbitrary input
    param input the input to return the condition for
    return true if the condition is met false otherwise

InfiniteColumnCondition

[source]
A column condition that simply checks whether a floating point value is infinite
columnCondition
1
public boolean columnCondition(Writable writable)
Copied!
    param columnName Column check for the condition

IntegerColumnCondition

[source]
columnCondition
1
public boolean columnCondition(Writable writable)
Copied!
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
1
public boolean condition(Object input)
Copied!
Condition on arbitrary input
    param input the input to return the condition for
    return true if the condition is met false otherwise

InvalidValueColumnCondition

[source]
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.
