MessagePattern.Part
extends Object
java.lang.Object | |
↳ | android.icu.text.MessagePattern.Part |
A message pattern "part", representing a pattern parsing event. There is a part for the start and end of a message or argument, for quoting and escaping of and with ASCII apostrophes, and for syntax elements of "complex" arguments.

Public methods
equals
public boolean equals (Object other)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation
on non-null object references:
- It is reflexive: for any non-null reference value
x
,x.equals(x)
should returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
Parameters | |
---|---|
other |
Object : another object to compare with. |
Returns | |
---|---|
boolean |
true if this object is equivalent to the other one. |
getArgType
public MessagePattern.ArgType getArgType ()
Returns the argument type if this part is of type ARG_START or ARG_LIMIT, otherwise ArgType.NONE.
Returns | |
---|---|
MessagePattern.ArgType |
the argument type for this part. |
getIndex
public int getIndex ()
Returns the pattern string index associated with this Part.
Returns | |
---|---|
int |
this part's pattern string index. |
getLength
public int getLength ()
Returns the length of the pattern substring associated with this Part. This is 0 for some parts.
Returns | |
---|---|
int |
this part's pattern substring length. |
getLimit
public int getLimit ()
Returns the pattern string limit (exclusive-end) index associated with this Part. Convenience method for getIndex()+getLength().
Returns | |
---|---|
int |
this part's pattern string limit index, same as getIndex()+getLength(). |
getType
public MessagePattern.Part.Type getType ()
Returns the type of this part.
Returns | |
---|---|
MessagePattern.Part.Type |
the part type. |
getValue
public int getValue ()
Returns a value associated with this part. See the documentation of each part type for details.
Returns | |
---|---|
int |
the part value. |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap
.
The general contract of hashCode
is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals
method, then calling thehashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns | |
---|---|
int |
a hash code value for this object. |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of this part. |
