Definition

Overloads

IsUnicodeIdentifierPart(Int32)

Determines if the specified character (Unicode code point) may be part of a Unicode identifier as other than the first character.

IsUnicodeIdentifierPart(Char)

Determines if the specified character may be part of a Unicode identifier as other than the first character.

IsUnicodeIdentifierPart(Int32)

Determines if the specified character (Unicode code point) may be part of a Unicode identifier as other than the first character.

[Android.Runtime.Register("isUnicodeIdentifierPart", "(I)Z", "")]
public static bool IsUnicodeIdentifierPart (int codePoint);
[<Android.Runtime.Register("isUnicodeIdentifierPart", "(I)Z", "")>]
static member IsUnicodeIdentifierPart : int -> bool

Parameters

codePoint
Int32

the character (Unicode code point) to be tested.

Returns

true if the character may be part of a Unicode identifier; false otherwise.

Attributes

Remarks

Determines if the specified character (Unicode code point) may be part of a Unicode identifier as other than the first character.

A character may be part of a Unicode identifier if and only if one of the following statements is true: <ul> <li> it is a letter <li> it is a connecting punctuation character (such as '_') <li> it is a digit <li> it is a numeric letter (such as a Roman numeral character) <li> it is a combining mark <li> it is a non-spacing mark <li> isIdentifierIgnorable returns true for this character. <li> it is an Other_ID_Starthttp://www.unicode.org/reports/tr44/#Other_ID_Start character. <li> it is an Other_ID_Continuehttp://www.unicode.org/reports/tr44/#Other_ID_Continue character. </ul>

This method conforms to UAX31-R1: Default Identifiers requirement of the Unicode Standard, with the following profile of UAX31:

Continue := Start + ID_Continue + ignorable
            Medial := empty
            ignorable := isIdentifierIgnorable(int) returns true for the character

ignorable is added to Continue for backward compatibility.

Added in 1.5.
