Class VarString
java.lang.Object
one.microstream.chars.VarString
- All Implemented Interfaces:
Serializable
,Appendable
,CharSequence
public final class VarString extends Object implements CharSequence, Appendable, Serializable
Faster implementation of a StringBuilder with richer functionality.
Note that this class is NOT synchronized and only meant for single-threaded or thread-safe
(i.e. read only or explicitly synchronized) use.

Nested Class Summary
Nested Classes Modifier and Type Class Description static interface
VarString.Appendable
Implementors of this interface handle appending their specific string representation directly.
This is useful for preventing the instantiation and copying of potentially large temporary strings which can have unnecessary and devastatingly negative effects on performance. -
