Method Details

reevaluateRootLevel

protected abstract boolean reevaluateRootLevel(@Nonnull
 T root)
                                        throws CtxEvalException

Invoked on the end of root macro processing. Should drop text into tail and parse again. Returns true if text has changed after extra processing step.

Throws:

CtxEvalException

reduce

protected abstract void reduce(@Nonnull
 T parent,
 @Nonnull
 T child)
                        throws CtxEvalException

Child will be thrown away. Child is evaluated - content in it's text. Parent may has an arguments, which should be reevaluated too. Sample: this.tail.append(parent.args).append(child.text).append(")"); parent.args.clear();

Throws:

CtxEvalException

read

protected void read(Token token)
             throws CtxEvalException

Throws:

CtxEvalException

reduceTreeLevel

public boolean reduceTreeLevel()
                        throws CtxEvalException

Invoked on the end of siblings processing. End of macros tree level processing. Should union edge with parent, push the union result into tokens, return new edge. Or return false if no parent to union with and this is a root level.

Throws:

CtxEvalException

assertEvaluationEnded

public void assertEvaluationEnded()
                           throws CtxEvalException

Evaluation result will be in state text.

Throws:

CtxEvalException

createChildContext

protected abstract T createChildContext(@Nonnull
 T parent,
 @Nonnull
 String macro)

toString

public String toString()

Overrides:

toString in class Object
