java.lang.IllegalArgumentException - if id.isEmpty()

java.lang.NullPointerException - if id == null

getIndexIfIndexed

public int getIndexIfIndexed(java.lang.String id)

Returns the index of the specified chromosome identifier, or returns -1 if the specified chromosome identifier is not indexed.

Parameters:

id - a chromosome identifier.

Returns:

the index of the specified chromosome identifier, or -1 if the specified chromosome identifier is not indexed.

Throws:

java.lang.IllegalArgumentException - if id.isEmpty()

java.lang.NullPointerException - if id == null

size

public int size()

Returns the number of indexed chromosomes identifiers.

Returns:

the number of indexed chromosomes identifiers

id

public java.lang.String id(int index)

Returns the chromosome identifier with the specified index.

Parameters:

index - a chromosome identifier index.

Returns:

the specified chromosome identifier.

Throws:

java.lang.IndexOutOfBoundsException - if index < 0 || index >= this.size()

ids

public java.lang.String[] ids()

Returns the list of chromosome identifiers as an array. The returned array will have length this.size(), and it will satisfy this.ids()[k].equals(this.id(k)) == true for 0 <= k < this.size().
