Description copied from class: AbstractConverterTable

Looks up a dictionary entry by pinyin. This won't be called until after the intialization is completed.

Specified by:

postInitLookupByPinyin in class AbstractConverterTable

Parameters:

pinyin - The input string is specified in pinyin. The string may be composed of the letters 'a'-'z' (lower case only), the numbers '1'-'5' and space (' '). The string is composed of at least 1 space-separated pinyin syllables. Syllables are separated with exactly one space. There is no leading or trailing space. Each syllable is composed of at least two letters followed by exactly one digit. The neutral tone is expicitly specified with '5'. u w/ umlaut (as in luu2 (donkey, palm tree), or luu3 (drizzle) is specified with uu.
