                          java.lang.String end)

Description copied from interface: com.gs.collections.api.RichIterable

Returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in the start and end strings. Adjacent elements are separated by the separator string. Elements are converted to strings as by String.valueOf(Object).

Specified by:

makeString in interface com.gs.collections.api.RichIterable<T>

Returns:

a string representation of this collection.

appendString

public void appendString(java.lang.Appendable appendable)

Description copied from interface: com.gs.collections.api.RichIterable

Prints a string representation of this collection onto the given Appendable. Prints the string returned by RichIterable.makeString().

zip

public <S,R extends java.util.Collection<com.gs.collections.api.tuple.Pair<T,S>>> R zip(java.lang.Iterable<S> that,

Description copied from interface: com.gs.collections.api.RichIterable

Same as RichIterable.zip(Iterable) but uses target for output.

zipWithIndex

public <R extends java.util.Collection<com.gs.collections.api.tuple.Pair<T,java.lang.Integer>>> R zipWithIndex(R target)

Description copied from interface: com.gs.collections.api.RichIterable

Same as RichIterable.zipWithIndex() but uses target for output.

Specified by:

chunk

public com.gs.collections.api.RichIterable<com.gs.collections.api.RichIterable<T>> chunk(int size)

Description copied from interface: com.gs.collections.api.RichIterable

Partitions elements in fixed size chunks.

Specified by:

chunk in interface com.gs.collections.api.RichIterable<T>

Parameters:

size - the number of elements per chunk

Returns:

A RichIterable containing RichIterables of size size, except the last will be truncated if the elements don't divide evenly.

aggregateInPlaceBy

public <K,V> com.gs.collections.api.map.MutableMap<K,V> aggregateInPlaceBy(com.gs.collections.api.block.function.Function<? super T,? extends K> groupBy,

Description copied from interface: com.gs.collections.api.RichIterable

Applies an aggregate procedure over the iterable grouping results into a Map based on the specific groupBy function. Aggregate results are required to be mutable as they will be changed in place by the procedure. A second function specifies the initial "zero" aggregate value to work with (i.e. new AtomicInteger(0)).

Description copied from interface: com.gs.collections.api.RichIterable

Applies an aggregate function over the iterable grouping results into a map based on the specific groupBy function. Aggregate results are allowed to be immutable as they will be replaced in place in the map. A second function specifies the initial "zero" aggregate value to work with (i.e. Integer.valueOf(0)).
