Method Detail

visitMethodCallExpression

public void visitMethodCallExpression(MethodCallExpression call)

Attempts to find AstBuilder 'from code' invocations. When found, converts them into calls to the 'from string' approach.

Specified by:

visitMethodCallExpression in interface GroovyCodeVisitor

Overrides:

visitMethodCallExpression in class CodeVisitorSupport

Parameters:

call - the method call expression that may or may not be an AstBuilder 'from code' invocation.

addError

protected void addError(String msg,
                        ASTNode expr)

Reports an error back to the source unit.

Parameters:

msg - the error message

expr - the expression that caused the error message.

convertClosureToSource

protected String convertClosureToSource(ClosureExpression expression)

Converts a ClosureExpression into the String source.

Parameters:

expression - a closure

Returns:

the source the closure was created from

handleTargetMethodCallExpression

protected abstract boolean handleTargetMethodCallExpression(MethodCallExpression call)

isBuildInvocation

protected abstract boolean isBuildInvocation(MethodCallExpression call)
