Method | Description | |
---|---|---|
BuildExpression ( int pri ) : void |
Builds expression tree for higher-precedence operator to be used as left operand of current operator. May cause errors - always do ErrorCheck() upin return.

|
CheckToken ( Tokens token ) : void | ||
ExpressionParser ( |
||
IsAlpha ( char ch ) : bool |
is the character an alpha?
|
|
IsAlphaNumeric ( char ch ) : bool |
is the character an alphanumeric?
|
|
IsDigit ( char ch ) : bool | ||
IsWhiteSpace ( char ch ) : bool |
is the character a white space character? Consider using CharacterInfo().IsWhiteSpace(ch) (System.Globalization)
|
|
LoadExpression ( string data ) : void | ||
NodePeek ( ) : |
NodePeek - Peek at the top node.
|
|
NodePop ( ) : |
NodePop - Pop an operand node from the node stack.
|
|
NodePush ( |
Push an operand node onto the node stack
|
|
Parse ( ) : |
||
ParseAggregateArgument ( FunctionId aggregate ) : |
Parse the argument to an Aggregate function. The syntax is Func(child[(relation_name)].column_name) When the function is called we have already parsed the Aggregate name, and open paren
|
|
Scan ( ) : Tokens | ||
ScanBinaryConstant ( ) : void | ||
ScanDate ( ) : void |
Just read the string between '#' signs, and parse it later
|
|
ScanName ( ) : void |
Just a string of alphanumeric characters.
|
|
ScanName ( char chEnd, char esc, string charsToEscape ) : void |
recognize bracketed identifiers. Special case: we are using '\' character to escape '[' and ']' only, so '\' by itself is not an escape
|
|
ScanNumeric ( ) : void |
ScanNumeric - parse number. In format: [digit|.]*{[e|E]{[+|-]}{digit*}} Further checking is done by constant parser.

ScanReserved ( ) : void | ||
ScanString ( char escape ) : void | ||
ScanToken ( Tokens token ) : void | ||
ScanWhite ( ) : void | ||
StartScan ( ) : void |
