AbstractRule

public AbstractRule()

Method Detail

getName

public abstract String getName()

Specified by:

getName in interface Rule

Returns:

the unique name for this rule

setName

public abstract void setName(String name)

Set the unique name for this rule

Parameters:

name - - the name for this rule; this should be unique

getPriority

public abstract int getPriority()

Specified by:

getPriority in interface Rule

Returns:

the priority of this rule, between 1 (highest priority) and 3 (lowest priority), inclusive.

setPriority

public abstract void setPriority(int priority)

Set the priority for this rule

Parameters:

priority - - the priority of this rule, between 1 (highest priority) and 3 (lowest priority), inclusive.

getCompilerPhase

public int getCompilerPhase()

Specified by:

getCompilerPhase in interface Rule

Returns:

the required compiler phase (as in Phases) of the AST of the SourceCode handed to the rule via applyTo(SourceCode sourceCode)

applyTo

public abstract void applyTo(SourceCode sourceCode,
                             List<Violation> violations)

Apply this rule to the specified source and return a list of violations (or an empty List)

Parameters:

sourceCode - - the source to apply this rule to

violations - - the List of violations to which new violations from this rule are to be added

applyTo

public List<Violation> applyTo(SourceCode sourceCode)
                        throws Throwable

Apply this rule to the specified source and return a list of violations (or an empty List). This implementation delegates to the abstract applyCode(SourceCode,List), provided by concrete subclasses. This template method simplifies subclass implementations and also enables common handling of enablement logic.

Specified by:

applyTo in interface Rule

Parameters:

sourceCode - - the source to apply this rule to

Returns:

the List of violations; may be empty

Throws:

Throwable - could throw anything

isReady

public boolean isReady()

Allows rules to check whether preconditions are satisfied and short-circuit execution (i.e., do nothing) if those preconditions are not satisfied. Return true by default. This method is provided as a placeholder so subclasses can optionally override.

Returns:

true if all preconditions for this rule are satisfied

validate

public void validate()

Allows rules to perform validation. Do nothing by default. This method is provided as a placeholder so subclasses can optionally override. Subclasses will typically use assert calls to verify required preconditions.

toString

public String toString()

Overrides:

toString in class Object

createViolation

protected Violation createViolation(Integer lineNumber,
                                    String sourceLine,
                                    String message)

Create and return a new Violation for this rule and the specified values

Parameters:

lineNumber - - the line number for the violation; may be null

sourceLine - - the source line for the violation; may be null

message - - the message for the violation; may be null

Returns:

a new Violation object

createViolation

protected Violation createViolation(SourceCode sourceCode,
                                    org.codehaus.groovy.ast.ASTNode node,
                                    String message)

Create a new Violation for the AST node.

Parameters:

sourceCode - - the SourceCode

node - - the Groovy AST Node

message - - the message for the violation; defaults to null

createViolationForImport

protected Violation createViolationForImport(SourceCode sourceCode,
                                             org.codehaus.groovy.ast.ImportNode importNode,
                                             String message)

Create and return a new Violation for this rule and the specified import

Parameters:

sourceCode - - the SourceCode

importNode - - the ImportNode for the import triggering the violation

Returns:

a new Violation object

createViolationForImport

protected Violation createViolationForImport(SourceCode sourceCode,
                                             String className,

                                             String violationMessage)

Parameters:

sourceCode - - the SourceCode

className - - the class name (as specified within the import statement)
