Class JavaPropsFactory.ReadConstrainedReader

java.lang.Object

java.io.Reader

com.fasterxml.jackson.dataformat.javaprop.JavaPropsFactory.ReadConstrainedReader

All Implemented Interfaces:

Closeable, AutoCloseable, Readable

Enclosing class:

JavaPropsFactory

private static class JavaPropsFactory.ReadConstrainedReader
extends Reader

Reader decorator that enforces StreamReadConstraints.getMaxDocumentLength() by counting characters read through it. Needed since actual decoding is done by Properties.load(Reader), reading content directly from a Reader, so the parser itself does not see input as it is consumed.

Only installed when constraints define a maximum document length (see StreamReadConstraints.hasMaxDocumentLength()).

Since:

2.18.11
