public long toLong()

Provides the long integer representation of this FeatureData.

Returns:

long representation of this FeatureData.

toFloat

public float toFloat()

Provides the float representation of this FeatureData.

Returns:

float representation of this FeatureData.

toDouble

public double toDouble()

Provides the double precision floating-point representation of this FeatureData.

Returns:

double representation of this FeatureData.

toString

public java.lang.String toString()

Provides the String-based representation of this FeatureData.

Returns:

toBytes

public byte[] toBytes()

Retrieves the binary byte array representation of this FeatureData.

compareTo

public int compareTo(galileo.dataset.feature.FeatureData<?> featureData)

Specified by:

compareTo in interface java.lang.Comparable<galileo.dataset.feature.FeatureData<?>>

serialize

public void serialize(galileo.serialization.SerializationOutputStream out)
               throws java.io.IOException

Specified by:

serialize in interface galileo.serialization.ByteSerializable

Throws:

java.io.IOException

toIntInterval

public Pair<java.lang.Integer,java.lang.Integer> toIntInterval()

Provides the integer-based interval representation of this FeatureData. If the FeatureData does not contain an interval (i.e., it is just a single point) then the start and end points of the interval will be the same value.

Returns:

integer interval representation of this FeatureData.

toLongInterval

public Pair<java.lang.Long,java.lang.Long> toLongInterval()

Provides the long integer-based interval representation of this FeatureData. If the FeatureData does not contain an interval (i.e., it is just a single point) then the start and end points of the interval will be the same value.

Returns:

long interval representation of this FeatureData.

toFloatInterval

public Pair<java.lang.Float,java.lang.Float> toFloatInterval()

Provides the floating point interval representation of this FeatureData. If the FeatureData does not contain an interval (i.e., it is just a single point) then the start and end points of the interval will be the same value.

Returns:

float interval representation of this FeatureData.

toDoubleInterval

public Pair<java.lang.Double,java.lang.Double> toDoubleInterval()

Provides the double-precision floating point interval representation of this FeatureData. If the FeatureData does not contain an interval (i.e., it is just a single point) then the start and end points of the interval will be the same value.

Returns:

double interval representation of this FeatureData.

getType

public FeatureType getType()

Return this FeatureData's type.

Returns:

the FeatureType for this FeatureData.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
