Expresser_TS(Pharacter character)

Method Summary

java.util.Collection<Expression>	express(Colony colony, Gene... genes) TODO this is apparently called more often than necessary
Trait	express(Gene... genes) Express the genes.
java.lang.String	getComplement(Locus locus, java.lang.String allele) In this implementation, if the locus is a swap, then we simply return the allele passed in because two identical swaps are complementary.
boolean	isComplementary(Locus locus, java.lang.String allele1, java.lang.String allele2) In this implementation of isComplementary, there are two situations: swap or rotate.

Method Detail

express

public java.util.Collection<Expression> express(Colony colony,
                                                Gene... genes)

TODO this is apparently called more often than necessary

Specified by:

express in interface Expresser

Overrides:

express in class Expresser_

Parameters:

colony - (which may be null)

genes - one gene or a set of polygenic genes.

Returns:

a collection of objects which are either a Trait or an ExPhen

See Also:

Expresser_.express(com.rubecula.darwin.domain.helper.Colony, com.rubecula.darwin.domain.helper.Gene[])

express

public Trait express(Gene... genes)

Description copied from interface: Expresser

Express the genes.

Returns:

a Trait

See Also:

Expresser.express(com.rubecula.darwin.domain.helper.Gene[])

getComplement

public java.lang.String getComplement(Locus locus,
                                      java.lang.String allele)

In this implementation, if the locus is a swap, then we simply return the allele passed in because two identical swaps are complementary. Otherwise, we invoke the super-method.

Specified by:

getComplement in interface Expresser

Overrides:

getComplement in class Expresser_

Returns:

the complementary allele key.

See Also:

Expresser_.getComplement(com.rubecula.darwin.domain.helper.Locus, java.lang.String)

isComplementary

public boolean isComplementary(Locus locus,
                               java.lang.String allele1,
                               java.lang.String allele2)

In this implementation of isComplementary, there are two situations: swap or rotate. Two adjacent swaps are complementary if the alleles are equal. Two adjacent rotations are complementary if the sum of the number of places rotated is zero.

Specified by:

isComplementary in interface Expresser

Overrides:

isComplementary in class Expresser_

Returns:

true if the alleles are complementary, i.e. if expressed sequentially, the result would be the same as if they had not been expressed at all.
