Class MultimapJoiner

java.lang.Object

org.eclipse.xtext.xbase.typesystem.util.MultimapJoiner

public class MultimapJoiner
extends java.lang.Object

An object that joins multimaps in the same manner as Joiner joins iterables and arrays. Like Joiner, it is thread-safe and immutable.

In contrast to using a Joiner.MapJoiner in conjunction with Multimap, the MultimapJoiner allows to use a custom joiner for the values of an entry.

Method Detail

appendTo

public <A extends java.lang.Appendable> A appendTo(A appendable,
                                          com.google.common.collect.Multimap<?,?> map)
                                        throws java.io.IOException

Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to appendable.

Throws:

java.io.IOException

appendTo

public <A extends java.lang.Appendable> A appendTo(A appendable,
                                          java.util.Map<?,? extends java.util.Collection<?>> map)
                                        throws java.io.IOException

Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to appendable.

Throws:

java.io.IOException

appendTo

public java.lang.StringBuilder appendTo(java.lang.StringBuilder builder,
                               com.google.common.collect.Multimap<?,?> map)

Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to builder. Identical to appendTo(Appendable, Multimap), except that it does not throw IOException.

appendTo

public java.lang.StringBuilder appendTo(java.lang.StringBuilder builder,
                               java.util.Map<?,? extends java.util.Collection<?>> map)

Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to builder. Identical to appendTo(Appendable, Map), except that it does not throw IOException.

join

public java.lang.String join(com.google.common.collect.Multimap<?,?> map)

Returns a string containing the string representation of each entry of map, using the previously configured separator and key-value separator.

appendTo

public <A extends java.lang.Appendable> A appendTo(A appendable,
                                          java.lang.Iterable<? extends java.util.Map.Entry<?,? extends java.util.Collection<?>>> entries)
                                        throws java.io.IOException

Appends the string representation of each entry in entries, using the previously configured separator and key-value separator, to appendable.

Throws:

java.io.IOException

appendTo

public java.lang.StringBuilder appendTo(java.lang.StringBuilder builder,
                               java.lang.Iterable<? extends java.util.Map.Entry<?,? extends java.util.Collection<?>>> entries)

Appends the string representation of each entry in entries, using the previously configured separator and key-value separator, to builder. Identical to appendTo(Appendable, Iterable), except that it does not throw IOException.
