public AbstractAstVisitor()

Method Detail

isFirstVisit

protected boolean isFirstVisit(java.lang.Object expression)

Return true if the AST expression has not already been visited. If it is the first visit, register the expression so that the next visit will return false.

Parameters:

expression - - the AST expression to check

Returns:

true if the AST expression has NOT already been visited

sourceLineTrimmed

protected java.lang.String sourceLineTrimmed(org.codehaus.groovy.ast.ASTNode node)

Return the trimmed source line corresponding to the specified AST node

Parameters:

node - - the Groovy AST node

sourceLine

protected java.lang.String sourceLine(org.codehaus.groovy.ast.ASTNode node)

Return the raw source line corresponding to the specified AST node

Parameters:

node - - the Groovy AST node

lastSourceLine

protected java.lang.String lastSourceLine(org.codehaus.groovy.ast.ASTNode node)

Return the last raw source line corresponding to the specified AST node

Parameters:

node - - the Groovy AST node

lastSourceLineTrimmed

protected java.lang.String lastSourceLineTrimmed(org.codehaus.groovy.ast.ASTNode node)

Return the trimmed last source line corresponding to the specified AST node

Parameters:

node - - the Groovy AST node

addViolation

protected void addViolation(org.codehaus.groovy.ast.ASTNode node,
                            java.lang.String message)

Add a new Violation to the list of violations found by this visitor. Only add the violation if the node lineNumber >= 0.

Parameters:

node - - the Groovy AST Node

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

addViolation

protected void addViolation(org.codenarc.rule.Violation violation)

Add a new Violation to the list of violations found by this visitor.

Parameters:

violation - - the violation to add
