Method Detail

size

public int size()

Description copied from interface: Traversable

Returns the size of the collection.

Warning: infinite collections are possible, as are collections that require traversal to calculate the size.

Specified by:

size in interface Traversable<E>

makeString

@NotNull
public String makeString(@NotNull
                                 String separator)

Description copied from interface: Traversable

Returns this collection converted to a string by joining elements together with the specified separator.

Specified by:

Description copied from interface: Traversable

Returns this collection converted to a string.

Specified by:

makeString in interface Traversable<E>

Parameters:

separator - Specifies the joining character

prefix - Specifies a prefix to the string

postfix - Species a postfix to the string
