Class Joiner.MapJoiner

java.lang.Object
  extended by com.google.common.base.Joiner.MapJoiner
Enclosing class:
Joiner

public static final class Joiner.MapJoiner
extends Object

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

In addition to operating on Map instances, MapJoiner can operate on Multimap entries in two distinct modes:

Method Summary
<A extends Appendable>
A
appendTo(A appendable, Iterable<? extends Map.Entry<?,?>> entries)

<A extends Appendable>
A
appendTo(A appendable, Map<?,?> map)
          Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to appendable.
 StringBuilder appendTo(StringBuilder builder, Iterable<? extends Map.Entry<?,?>> entries)
          Appends the string representation of each entry in entries, using the previously configured separator and key-value separator, to builder.
 StringBuilder appendTo(StringBuilder builder, Map<?,?> map)
          Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to builder.
 String join(Iterable<? extends Map.Entry<?,?>> entries)
          Returns a string containing the string representation of each entry in entries, using the previously configured separator and key-value separator.
 String join(Map<?,?> map)
          Returns a string containing the string representation of each entry of map, using the previously configured separator and key-value separator.

Method Detail

appendTo

public <A extends Appendable> A appendTo(A appendable,
                                         Map<?,?> map)
                              throws IOException
Appends the string representation of each entry of map, using the previously configured separator and key-value separator, to appendable.

Throws:
IOException

appendTo

public StringBuilder appendTo(StringBuilder builder,
                              Map<?,?> 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 String join(Map<?,?> map)
Returns a string containing the string representation of each entry of map, using the previously configured separator and key-value separator.
