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:

• To output a separate entry for each key-value pair, pass multimap.entries() to a MapJoiner method that accepts entries as input, and receive output of the form key1=A&key1=B&key2=C.
• To output a single entry for each key, pass multimap.asMap() to a MapJoiner method that accepts a map as input, and receive output of the form key1=[A, B]&key2=C.

方法摘要

<A extends Appendable> A	appendTo(A appendable, Iterable<? extends Map.Entry<?,?>> entries) Appends the string representation of each entry in entries, using the previously configured separator and key-value separator, to appendable.
<A extends Appendable> A	appendTo(A appendable, Iterator<? extends Map.Entry<?,?>> parts) Appends the string representation of each entry in entries, using the previously configured separator and key-value separator, to appendable.
<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, Iterator<? 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(Iterator<? 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.
Joiner.MapJoiner	useForNull(String nullText) Returns a map joinKit with the same behavior as this one, except automatically substituting nullText for any provided null keys or values.

方法详细信息

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.

抛出：

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.
