Constructor Detail

CRFDatum

public CRFDatum(java.util.List<FEAT> features,
                LAB label)

Constructs a new BasicDatum with the given features and label.

Parameters:

features - The features of the CRFDatum

label - The label of the CRFDatum

Method Detail

asFeatures

public java.util.List<FEAT> asFeatures()

Returns the collection that this BasicDatum was constructed with.

Returns:

the collection that this BasicDatum was constructed with.

label

public LAB label()

Returns the label for this Datum, or null if none have been set.

Returns:

The label for this Datum, or null if none have been set.

toString

public java.lang.String toString()

Returns a String representation of this BasicDatum (lists features and labels).

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Returns whether the given Datum contains the same features as this Datum. Doesn't check the labels, should we change this? (CDM Feb 2012: Also doesn't correctly respect the contract for equals, since it gives one way equality with other Datum's.)

Overrides:

equals in class java.lang.Object

Parameters:

o - The object to test equality with

Returns:

Whether it is equal to this CRFDatum in terms of features

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
