public sealed class JSScanner

The JSScanner type exposes the following members.

Public methodJSScanner()Initializes a new instance of the JSScanner class.
Public methodJSScanner(Context)Initializes a new instance of the JSScanner class, specifying the source code to scan.

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetCurrentLineGets the current line number in the code. This is a pointer that moves as the code is scanned.
Public methodGetCurrentPositionGets the current position in the code string. This is a pointer that moves as the code is scanned.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetNextTokenScans for the next token in the code.
Public methodGetSourceCodeGets the source code that is associated with this scanner object.
Public methodGetStartLinePositionGets the position in the code string where the first line of the current code starts. All lines of code are stored in a single string. This is a pointer that moves as the code is scanned.
Public methodGetStringLiteralGets a string that has been scanned and had all its escape sequences replaced.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGotEndOfLineIndicates whether the end of a line was reached after the scanner scans or peeks for a token.
Public methodStatic memberIsKeywordDetermines whether the specified token is a keyword in the JScript language.
Public methodStatic memberIsOperatorDetermines whether the specified token is an operator in the JScript language.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodSetAuthoringModeSets a flag that indicates whether the scanner is operating in authoring mode.
Public methodSetSourceSets the source code to scan.
Public methodSkipMultiLineCommentSkips a comment that spans multiple lines, and advances the pointers that identify the current position in the code.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)
