Method Detail

createNamedLength

public static java.lang.String createNamedLength(java.lang.String propertyName,
                                                 long length)

Returns a named length for use as a term in the index. The named length is of the form: propertyName + '[' + LongField.longToString(long).

Parameters:

propertyName - a property name.

length - the length of the property value.

Returns:

the named length string for use as a term in the index.

createNamedValue

public static java.lang.String createNamedValue(java.lang.String fieldName,
                                                java.lang.String value)

Returns a named value for use as a term in the index. The named value is of the form: fieldName + '[' + value

Parameters:

fieldName - the field name.

value - the value.

Returns:

value prefixed with field name.

getNameLength

public static int getNameLength(java.lang.String namedValue)

Returns the length of the field prefix in namedValue. See also createNamedValue(String, String). If namedValue does not contain a name prefix, this method return 0.

Parameters:

namedValue - the named value as created by createNamedValue(String, String).

Returns:

the length of the field prefix including the separator char '['.
