Method Detail

synchronize

public static <T extends CharSequence> StringMap<T> synchronize(StringMap<T> stringMap)

Returns a synchronized string map backed by the given string map.

Parameters:

stringMap - the string map to be wrapped in a synchronized map.

Returns:

a synchronized view of the specified string map.

synchronize

public static <T extends CharSequence> PrefixMap<T> synchronize(PrefixMap<T> prefixMap)

Returns a synchronized prefix map backed by the given prefix map.

Parameters:

prefixMap - the prefix map to be wrapped in a synchronized map.

Returns:

a synchronized view of the specified prefix map.

wrap

public static <T extends CharSequence> StringMap<T> wrap(StringMap<T> stringMap)

Returns an immutable (big) StringMap view of a standard StringMap.

Parameters:

stringMap - a string map.

Returns:

a StringMap view of stringMap.

wrap

public static <T extends CharSequence> PrefixMap<T> wrap(PrefixMap<T> prefixMap)

Returns an immutable (big) PrefixMap view of a standard PrefixMap. Note that the returned prefix map does not implement PrefixMap.prefixMap().

Parameters:

prefixMap - a prefix map.

Returns:

a PrefixMap view of prefixMap.
