public class IfModelHandler extends ch.qos.logback.core.model.processor.ModelHandlerBase
Handler responsible for processing IfModel instances encountered during model interpretation.

This handler pushes the IfModel onto the interpretation stack, validates the condition string and emits the corresponding Java "if" control flow into the Tyler configuration method being built (via MethodSpec).

    Description
    protected void
    addJavaStatement(TylerModelInterpretationContext tmic, String conditionStr)
    Emit the Java "if" control flow for the given condition into the supplied TylerModelInterpretationContext's MethodSpec builder.
    protected Class<ch.qos.logback.core.model.conditional.IfModel>
    getSupportedModelClass()
    Return the model class that this handler supports.
    void
    handle(ch.qos.logback.core.model.processor.ModelInterpretationContext mic, ch.qos.logback.core.model.Model model)
    Handle an IfModel by validating its condition and emitting the corresponding Java "if" statement into the Tyler method spec builder.
