GH_ExpressionParser Methods

Test a string for balanced open and close chars. You can use this function to see if brackets or parenthesis have been properly used.

Retrieve a copy of the Queue of cached symbols. You can use the cached symbols as an uber-optimization to speed up successive calls to Evaluate() with an identical expression string

Create a Symbols array from the expression. Use this method if you intend to evaluate the same expression multiple times. At this point, the expression has to be in correct syntax format. Use the GH_ExpressionSyntaxWriter.RewriteAll() method to make sure.

Destroy the Symbols cache.

Destroy the variable cache.

Evaluate the expression currently loaded in the Symbols cache using the currently loaded variables.

Evaluate the expression queue without overriding any local caches. You can obtain an expression queue by calling CachedSymbols()

Store a new expression in the Symbols cache and evaluate it using the current variables

Tests whether a string is a valid variable name for expressions. Valid names must contain at least one character, must start with an alphabetic character, and only contain alphanumeric chars and underscores.
