Method Summary

Modifier and Type	Method and Description
T	get() Completes the matching chain returned the matched result
<TT> ValueKey.BeforeThen<T,TT>	ifEq(ValueKey<TT> key) Continues a matching chain: the subsequent then-branch will take effect if the supplied "case" key equals to the selector key
T	orNull() Completes the matching chain returned the matched result

Method Detail

ifEq

<TT> ValueKey.BeforeThen<T,TT> ifEq(ValueKey<TT> key)

Continues a matching chain: the subsequent then-branch will take effect if the supplied "case" key equals to the selector key

Type Parameters:

TT - type of the "case" key

Parameters:

key - "case" key to compare with selector key

Returns:

a matching chain in the then-state (then-branches are accepted afterwards)

get

T get()

Completes the matching chain returned the matched result

Returns:

the result of matching, supplied by the "then"-branch which follows the "case"-key matching the selector. Could be null, if the corresponding "then"-branch produced a null value.

Throws:

java.util.NoSuchElementException - if no "case"-key matched the selector.

orNull

T orNull()

Completes the matching chain returned the matched result

Returns:

the result of matching, supplied by the "then"-branch which follows the "case"-key matching the selector. Returns null if no "case"-key matched the selector, or the corresponding "then"-branch produced a null value.
