Method Summary

Modifier and Type	Method and Description
void	encodeValue(BCF2Encoder encoder, java.lang.Object value, BCF2Type type, int minValues) Key abstract method that should encode a value of the given type into the encoder.
boolean	hasConstantNumElements() True if this field has a constant, fixed number of elements (such as 1 for an atomic integer)
boolean	hasContextDeterminedNumElements() True if this field has a non-fixed number of elements that depends only on the properties of the current VariantContext, such as one value per Allele or per genotype configuration.
boolean	hasValueDeterminedNumElements() True if the only way to determine how many elements this field contains is by inspecting the actual value directly, such as when the number of elements is a variable length list per site or per genotype.
protected int	numElementsFromValue(java.lang.Object value) Given a value, return the number of elements we will encode for it.

Description copied from class: BCF2FieldEncoder

Key abstract method that should encode a value of the given type into the encoder. Value will be of a type appropriate to the underlying encoder. If the genotype field is represented as an int[], this will be value, and the encoder needs to handle encoding all of the values in the int[]. The argument should be used, not the getType() method in the superclass as an outer loop might have decided a more general type (int16) to use, even through this encoder could have been done with int8. If minValues > 0, then encodeValue must write in at least minValues items from value. If value is atomic, this means that minValues - 1 MISSING values should be added to the encoder. If minValues is a collection type (int[]) then minValues - values.length should be added. This argument is intended to handle padding of values in genotype fields.
