Document

Method that will force generator to copy input text verbatim with no modifications (including that no escaping is done and no separators are added even if context [array, object] would otherwise require such).

Usage

From source file:org.datagator.api.client.SpooledRowBuffer.java

public void flush() throws IOException {
    if (cacheFile.length() > 0) {
        cacheFile.seek(cacheFile.length() - 1);
    } else {//from w  w w.  j  a  v a 2  s  .c  o m
        cacheFile.seek(0);
    }
    FileWriter writer = new FileWriter(cacheFile.getFD());
    JsonGenerator jg = Entity.json.createGenerator(writer);
    if (rowsCount < 0) {
        jg.writeRaw(",\n");
    }
    for (Object[] v : this.cache) {
        jg.writeStartArray();
