Field Detail

regex

protected Regex regex

The regex represented by this terminal.

operatorClass

protected CopperElementReference operatorClass

The terminal's operator precedence class. Shift-reduce conflicts can only be resolved on operators within the same precedence class. If this is not set, the terminal will be placed into an anonymous "default" class.

operatorPrecedence

protected java.lang.Integer operatorPrecedence

The terminal's operator precedence.

operatorAssociativity

protected OperatorAssociativity operatorAssociativity

The terminal's operator associativity.

code

protected java.lang.String code

Code specifying a semantic action for this terminal.

terminalClasses

protected java.util.Set<CopperElementReference> terminalClasses

Terminal classes to which this terminal belongs.

submitList

protected java.util.Set<CopperElementReference> submitList

Terminals and/or terminal classes that take precedence over this terminal.

dominateList

protected java.util.Set<CopperElementReference> dominateList

Terminals and/or terminal classes over which this terminal takes lexical precedence.

prefix

protected CopperElementReference prefix

The terminal's transparent prefix.

public Terminal()

Method Detail

isComplete

public boolean isComplete()

Description copied from class: CopperASTBean

Checks that a grammar object has had values assigned to all its required elements and parameters. All objects require the fields name and location to be set, and may impose additional individual requirements.

Overrides:

isComplete in class CopperASTBean

Returns:

true iff all required elements and parameters have been set to non-null values.

whatIsMissing

public java.util.Set<java.lang.String> whatIsMissing()

Overrides:

whatIsMissing in class CopperASTBean

Returns:

A set containing the required elements or parameters that are missing in this grammar object.
