Package jetbrains.buildServer.serverSide.parameters

Class DepParametersMemoryOptimizedMap

java.lang.Object

java.util.AbstractMap<String,String>

jetbrains.buildServer.serverSide.parameters.DepParametersMemoryOptimizedMap

All Implemented Interfaces:

Map<String,String>

public class DepParametersMemoryOptimizedMap
extends AbstractMap<String,String>

This map is intended to reduce memory usage for the case of build parameters. Map knows about some commonly used parameter prefixes and maintains a pool of keys and values thus reducing the memory occupied by strings. For instance if map has keys like: dep..c dep..d c d Memory occupied by keys can be reduced if dep.. prefix is removed from the first two keys and stored separately. The map is not thread safe.

Since:

10.0.2
