Document

Method similar to #getText , but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information.

Usage

From source file:org.oscim.tiling.source.geojson.GeoJsonTileDecoder.java

private final static boolean match(JsonParser jp, char[] fieldName) throws JsonParseException, IOException {

    int length = jp.getTextLength();
    if (length != fieldName.length)
        return false;

    char[] val = jp.getTextCharacters();
    int offset = jp.getTextOffset();

    for (int i = 0; i < length; i++) {
        if (fieldName[i] != val[i + offset])
            return false;
    }//w ww  .  ja  va  2 s .c o  m

    return true;
}
