Internal class to manage character names. Since data for names are stored in an array of char, by default indexes used in this class is referring to a 2 byte count, unless otherwise stated. Cases where the index is referring to a byte count, the index is halved and depending on whether the index is even or odd, the MSB or LSB of the result char at the halved index is returned. For indexes to an array of int, the index is multiplied by 2, result char at the multiplied index and its following char is returned as an int. UCharacter acts as a public facade for this class Note : 0 - 0x1F are control characters without names in Unicode 3.0

getGroupNameback to summary
public String getGroupName(int index, int length, int choice)

In unames.icu, it is marked as token[';'] == -1 only if the semicolon is used in the data file - which is iff we have Unicode 1.0 names or ISO comments or aliases. So, it will be token[';'] == -1 if we store U1.0 names/ISO comments/aliases although we know that it will never be part of a name. Equivalent to ICU4C's expandName.

Method Detail

addback to summary
pack-priv int add(int[] set, int maxlength)

Adds all chars in the set of algorithmic names into the set. Equivalent to part of calcAlgNameSetsLengths.

Parameters
set:int[]

int set to add the chars of the algorithm names into

maxlength:int

maximum length to compare to

Returns:int

the length that is either maxlength of the length of this algorithm name if it is longer than maxlength

appendNameback to summary
pack-priv void appendName(int ch, StringBuffer str)

Appends algorithm name of code point into StringBuffer. Note this method does not check for validity of code point in Algorithm, result is undefined if code point does not belong in Algorithm.

Parameters
ch:int

code point

str:StringBuffer

StringBuffer to append to

compareFactorStringback to summary
private boolean compareFactorString(int[] index, int length, String str, int offset)

Compares the indexth string in each of the argument factor block with the argument string

Parameters
index:int[]

array with each index corresponding to each factor block

length:int

index array length

str:String

string to compare with

offset:int

of str to start comparison

Returns:boolean

true if string matches

containsback to summary
pack-priv boolean contains(int ch)

Checks if code point lies in Algorithm object at index

Parameters
ch:int

code point

getCharback to summary
pack-priv int getChar(String name)

Gets the character for the argument algorithmic name

Returns:int

the algorithmic char or -1 otherwise.

getFactorStringback to summary
private String getFactorString(int[] index, int length)

Gets the indexth string in each of the argument factor block

Parameters
index:int[]

array with each index corresponding to each factor block

length:int

length of the array index

Returns:String

the combined string of the array of indexth factor string in factor block

setFactorback to summary
pack-priv boolean setFactor(char[] factor)

Sets the factor data

Parameters
factor:char[]

Array of factor

Returns:boolean

true if factors are valid

setFactorStringback to summary
pack-priv boolean setFactorString(byte[] string)

Sets the variant factorized name data

Parameters
string:byte[]

variant factorized name data

Returns:boolean

true if values are set

setInfoback to summary
pack-priv boolean setInfo(int rangestart, int rangeend, byte type, byte variant)

Sets the information for accessing the algorithmic names

Parameters
rangestart:int

starting code point that lies within this name group

rangeend:int

end code point that lies within this name group

type:byte

algorithm type. There's 2 kinds of algorithmic type. First which uses code point as part of its name and the other uses variant postfix strings

variant:byte

algorithmic variant

Returns:boolean

true if values are valid

setPrefixback to summary
pack-priv boolean setPrefix(String prefix)

Sets the name prefix

Returns:boolean

true if prefix is set
