Libraries.Language.Compile.Symbol.SymbolTable

Ths SymbolTable class stores all pertinent information about a compile as it goes. It allows for querying of various kinds and stores only the information in its transitive dependency graph. However, in some instances, like in the use of IDE usage, a symbol table may contain a second table, called a standard library cache. This cache contains classes that are not used in the compile, but that are available to the compiler for use. This is useful for things like editor hints.

Returns whether the symbol table has any

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

This action returns a copy of the symbol table. Each class object inside of the table is a shallow copy of the original.

This action gathers all of the classes from the table variable and puts them into this symbol table, clearing out the table before starting. This action only copies the classes.

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

Returns a class with the corresponding unique static key.

This action returns an array of all classes that have a particular name regardless of their static key.

This action returns the first class in the file with the designated key.

finally, since it is unique, add it to the list of class names

Returns the number of classes in the symbol table.

This action returns a copy of the symbol table. Each class object inside of the table is a shallow copy of the original.

Returns all classes in a particular package.

This action returns an array of classes in a particular subpackage sorted by their static keys.

Returns the number of files in the symbol table.

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This stores the standard library cache. It contains any classes available to the system, regardless of whether they available in the current compile.

Returns the number of packages in the symbol table.

Returns an iterator of all loaded packages.

Returns an iterator of all loaded packages.

This action returns an array of classes in a particular subpackage sorted by their static keys.

create one

Returns whether or not a class exists in the symbol table. The key passed must be the full static key (i.e., Libraries.Language.Object, not Object).

Returns whether or not the symbol table has a file

This stores whether or not a standard library cache exists. There are good reasons why a cache may not exist. For example, if this symbol table is a cache, it won't have another one. Further, if scanning is turned off, then no cache will exist.

Returns whether the symbol table has any

Removes a class with a static key from the symbol table.

Removes a file, and any associated classes, from the system.

This action sets the standard library cache.

This action gathers all of the classes from the table variable and puts them into this symbol table, clearing out the table before starting. This action only copies the classes.
