java.lang.Objectcom.google.common.base.Joiner.MapJoiner
public static final class Joiner.MapJoiner
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:
multimap.entries()
to a
MapJoiner
method that accepts entries as input, and receive output of the form
key1=A&key1=B&key2=C
.
multimap.asMap()
to a MapJoiner
method that accepts a map as input, and receive output of the form key1=[A, B]&key2=C
.
Method Summary | ||
---|---|---|
|
appendTo(A appendable,
I entries)
Deprecated. use appendTo(Appendable, Iterator) by casting entries to
Iterator<? extends Entry<?, ?>> , or better yet, by implementing only
Iterator and not Iterable . This method is scheduled for deletion
in June 2013. |
|
|
appendTo(A appendable,
java.lang.Iterable<? extends java.util.Map.Entry<?,?>> entries)
Appends the string representation of each entry in entries , using the previously
configured separator and key-value separator, to appendable . |
|
|
appendTo(A appendable,
java.util.Iterator<? extends java.util.Map.Entry<?,?>> parts)
Appends the string representation of each entry in entries , using the previously
configured separator and key-value separator, to appendable . |
|
|
appendTo(A appendable,
java.util.Map<?,?> map)
Appends the string representation of each entry of map , using the previously
configured separator and key-value separator, to appendable . |
|
|
appendTo(java.lang.StringBuilder builder,
I entries)
Deprecated. use appendTo(StringBuilder, Iterator) by casting entries to
Iterator<? extends Entry<?, ?>> , or better yet, by implementing only
Iterator and not Iterable . This method is scheduled for deletion
in June 2013. |
|
java.lang.StringBuilder |
appendTo(java.lang.StringBuilder builder,
java.lang.Iterable<? extends java.util.Map.Entry<?,?>> entries)
Appends the string representation of each entry in entries , using the previously
configured separator and key-value separator, to builder . |
|
java.lang.StringBuilder |
appendTo(java.lang.StringBuilder builder,
java.util.Iterator<? extends java.util.Map.Entry<?,?>> entries)
Appends the string representation of each entry in entries , using the previously
configured separator and key-value separator, to builder . |
|
java.lang.StringBuilder |
appendTo(java.lang.StringBuilder builder,
java.util.Map<?,?> map)
Appends the string representation of each entry of map , using the previously
configured separator and key-value separator, to builder . |
|
|
join(I entries)
Deprecated. use join(Iterator) by casting entries to
Iterator<? extends Entry<?, ?>> , or better yet, by implementing only
Iterator and not Iterable . This method is scheduled for deletion
in June 2013. |
|
java.lang.String |
join(java.lang.Iterable<? extends java.util.Map.Entry<?,?>> entries)
Returns a string containing the string representation of each entry in entries , using
the previously configured separator and key-value separator. |
|
java.lang.String |
join(java.util.Iterator<? extends java.util.Map.Entry<?,?>> entries)
Returns a string containing the string representation of each entry in entries , using
the previously configured separator and key-value separator. |
|
java.lang.String |
join(java.util.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(java.lang.String nullText)
Returns a map joiner with the same behavior as this one, except automatically substituting nullText for any provided null keys or values. |
