Collections12.SingletonMap.ImmutableEntry
Collections12.SingletonMap.ImmutableEntry(java.lang.Object key,
java.lang.Object value)
getKey
public java.lang.Object getKey()
- Description copied from interface:
java.util.Map.Entry
- Get the key corresponding to this entry.
- Specified by:
getKey
in interface java.util.Map.Entry
getValue
public java.lang.Object getValue()
- Description copied from interface:
java.util.Map.Entry
- Get the value corresponding to this entry. If you already called
Iterator.remove(), this is undefined.
- Specified by:
getValue
in interface java.util.Map.Entry
setValue
public java.lang.Object setValue(java.lang.Object value)
- Description copied from interface:
java.util.Map.Entry
- Replaces the value with the specified object (optional operation).
This writes through to the map, and is undefined if you already
called Iterator.remove().
- Specified by:
setValue
in interface java.util.Map.Entry
equals
public boolean equals(java.lang.Object o)
- Description copied from interface:
java.util.Map.Entry
- Compares the specified object with this entry. Returns true only if
the object is a mapping of identical key and value. In other words,
this must be:
(o instanceof Map.Entry)
&& (getKey() == null ? ((Map.Entry) o).getKey() == null
: getKey().equals(((Map.Entry) o).getKey()))
&& (getValue() == null ? ((Map.Entry) o).getValue() == null
: getValue().equals(((Map.Entry) o).getValue()))
- Specified by:
equals
in interface java.util.Map.Entry
hashCode
public int hashCode()
- Description copied from interface:
java.util.Map.Entry
- Returns the hash code of the entry. This is defined as the
exclusive-or of the hashcodes of the key and value (using 0 for
null
). In other words, this must be:
(getKey() == null ? 0 : getKey().hashCode())
^ (getValue() == null ? 0 : getValue().hashCode())
- Specified by:
hashCode
in interface java.util.Map.Entry
toString
public java.lang.String toString()
- Description copied from class:
java.lang.Object
- Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into System.out.println() 55
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a java.lang.RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null
, string concatenation will instead
use "null"
.
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode())
.
