public final class: HitDetails [javadoc | source]

java.lang.Object
   org.apache.nutch.searcher.HitDetails

All Implemented Interfaces:
    org.apache.hadoop.io.Writable

Data stored in the index for a hit.

Represented as a list of name/value pairs.

Constructor:
public HitDetails() { }
public HitDetails(String[] fields, String[] values) { this.length = fields.length; this.fields = fields; this.values = values; } Construct from field names and values arrays.
public HitDetails(String segment, String url) { this(new String[2], new String[2]); this.fields[0] = "segment"; this.values[0] = segment; this.fields[1] = "url"; this.values[1] = url; } Construct minimal details from a segment name and document number.

Method from org.apache.nutch.searcher.HitDetails Detail:
public String getField(int i) { return fields[i]; } Returns the name of the ith field.
public int getLength() { return length; } Returns the number of fields contained in this.
public String getValue(int i) { return values[i]; } Returns the value of the ith field.
public String getValue(String field) { for (int i = 0; i < length; i++) { if (fields[i].equals(field)) return values[i]; } return null; } Returns the value of the first field with the specified name.
public String[] getValues(String field) { ArrayList< String > vals = new ArrayList< String >(); for (int i=0; i< length; i++) { if (fields[i].equals(field)) { vals.add(values[i]); } } return (vals.size() > 0) ? vals.toArray(new String[vals.size()]) : null; } Returns all the values with the specified name.
public static HitDetails read(DataInput in) throws IOException { HitDetails result = new HitDetails(); result.readFields(in); return result; } Constructs, reads and returns an instance.
public void readFields(DataInput in) throws IOException { length = in.readInt(); fields = new String[length]; values = new String[length]; for (int i = 0; i < length; i++) { fields[i] = in.readUTF(); values[i] = in.readUTF(); } }
public String toHtml() { StringBuffer buffer = new StringBuffer(); buffer.append("< ul >\n"); for (int i = 0; i < length; i++) { buffer.append("< li >"); buffer.append(fields[i]); buffer.append(" = "); buffer.append(Entities.encode(values[i])); buffer.append("< /li >\n"); } buffer.append("< /ul >\n"); return buffer.toString(); } Display as HTML.
public String toString() { return getValue("segment") + "/" + getValue("url"); } Display as a string.
public void write(DataOutput out) throws IOException { out.writeInt(length); for (int i = 0; i < length; i++) { out.writeUTF(fields[i]); out.writeUTF(values[i]); } }
