Source Link

Document

Creates a new instance that uses the given file threshold, and optionally resets the data when the ByteSource returned by #asByteSource is finalized.

Usage

From source file:eu.interedition.text.xml.XMLParserState.java

XMLParserState(Text source, Text target, XMLParserConfiguration configuration) {
    this.source = source;
    this.target = target;
    this.configuration = configuration;
    this.modules = configuration.getModules();
    this.textBuffer = new FileBackedOutputStream(configuration.getTextBufferSize(), true);
    this.lastChar = (configuration.isRemoveLeadingWhitespace() ? ' ' : 0);
