Namespace Detail

ilib.CType

Provides a set of static routines that return information about characters. These routines emulate the C-library ctype functions. The characters must be encoded in utf-16, as no other charsets are currently supported. Only the first character of the given string is tested.

Method Detail

<static> {boolean} ilib.CType.isAlnum(ch)

Return whether or not the first character is alphabetic or numeric.

Depends directive: !depends ctype.isalnum.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is alphabetic or numeric

<static> {boolean} ilib.CType.isAlpha(ch)

Return whether or not the first character is alphabetic.

Depends directive: !depends ctype.isalnum.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is alphabetic.

<static> {boolean} ilib.CType.isAscii(ch)

Return whether or not the first character is in the ASCII range.

Depends directive: !depends ctype.isascii.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is in the ASCII range.

<static> {boolean} ilib.CType.isBlank(ch)

Return whether or not the first character is a blank character.

Depends directive: !depends ctype.isblank.js ie. a space or a tab.

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is a blank character.

<static> {boolean} ilib.CType.isCntrl(ch)

Return whether or not the first character is a control character.

Depends directive: !depends ctype.iscntrl.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is a control character.

<static> {boolean} ilib.CType.isDigit(ch)

Return whether or not the first character is a digit character in the Latin script.

Depends directive: !depends ctype.isdigit.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is a digit character in the Latin script.

<static> {boolean} ilib.CType.isGraph(ch)

Return whether or not the first character is any printable character other than space.

Depends directive: !depends ctype.isgraph.js

Depends directive: !depends ctype.isprint.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is printable.

<static> {boolean} ilib.CType.isPunct(ch)

Return whether or not the first character is punctuation.

Depends directive: !depends ctype.isprint.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is punctuation.

<static> {boolean} ilib.CType.isScript(ch, script)

Return whether or not the first character in the given string is in the given script. The script is given as the 4-letter ISO 15924 script code.

Depends directive: !depends ctype.isscript.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine
{string} script: the 4-letter ISO 15924 to query against

Returns:: {boolean} true if the first character is in the given script, and false otherwise

<static> {boolean} ilib.CType.isSpace(ch)

Return whether or not the first character is a whitespace character.

Depends directive: !depends ctype.isspace.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is a whitespace character.

<static> {boolean} ilib.CType.isUpper(ch)

Return whether or not the first character is upper-case. For alphabetic characters in scripts that do not make a distinction between upper- and lower-case, this function always returns true.

Depends directive: !depends ctype.isupper.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is upper-case.

<static> {boolean} ilib.CType.isXdigit(ch)

Return whether or not the first character is a hexadecimal digit written in the Latin script. (0-9 or A-F)

Depends directive: !depends ctype.isxdigit.js

Parameters:
{string|ilib.String|number} ch: character or code point to examine

Returns:: {boolean} true if the first character is a hexadecimal digit written in the Latin script.

<static> {boolean} ilib.CType.withinRange(ch, rangeName)
