Method Detail

getOpType

public org.dmg.pmml.OpType getOpType()

Overrides:

getOpType in class ModelField

prepare

public FieldValue prepare(Object value)

Prepares the input value for a field.

First, the value is converted from the user-supplied representation to PMML representation. After that, the value is subjected to missing value treatment, invalid value treatment and outlier treatment.

Parameters:

value - The input value in user-supplied representation. Use null to represent a missing input value.

Throws:

EvaluationException - If the input value preparation fails.

InvalidMarkupException

UnsupportedMarkupException

getContinuousDomain

public com.google.common.collect.RangeSet<Double> getContinuousDomain()

Returns the domain of valid values for this continuous field. If specified, then all input values that are contained in this set shall be considered valid, and all others invalid. If not specified, then all input values shall be considered valid.

Returns:

A non-empty set, or null.

getOpType()

getDiscreteDomain

public List<?> getDiscreteDomain()

Returns the domain of valid values for this categorical or ordinal field. If specified, then all input values that are contained in this list shall be considered valid, and all others invalid. In not specified, then all input values shall be considered valid.

List elements are all valid values in PMML representation. For example, if the data type of this field is DataType.INTEGER, then all list elements shall be Integer.

Returns:

A non-empty list, or null.
