java.lang.Object
com.hazelcast.config.PersistentMemoryDirectoryConfig
public class PersistentMemoryDirectoryConfig extends Object
Configuration class for directories that persistent memories are mounted at.

  • Constructor Details

    • PersistentMemoryDirectoryConfig

      public PersistentMemoryDirectoryConfig(@Nonnull String directory)
      Creates an instance with the directory specified.
      Parameters:
      directory - The directory where the persistent memory is mounted at
      Throws:
      NullPointerException - if directory is null

    • PersistentMemoryDirectoryConfig

      public PersistentMemoryDirectoryConfig(@Nonnull String directory, int numaNode)
      Creates an instance with the directory and NUMA node specified.

      Note that setting numaNode to -1 on any of the configured PersistentMemoryDirectoryConfig instances disables NUMA-aware persistent memory allocation.

      Parameters:
      directory - The directory where the persistent memory is mounted at
      numaNode - The NUMA node that the persistent memory mounted to the given directory is attached to.
      Throws:
      NullPointerException - if directory is null

    • PersistentMemoryDirectoryConfig

      public PersistentMemoryDirectoryConfig(@Nonnull PersistentMemoryDirectoryConfig directoryConfig)
      Constructs an instance by copying the provided PersistentMemoryDirectoryConfig.
      Parameters:
      directoryConfig - The configuration to copy
      Throws:
      NullPointerException - if directoryConfig is null

      Returns:
      the directory

    • setDirectory

      public void setDirectory(@Nonnull String directory)
      Returns the directory of this PersistentMemoryDirectoryConfig.
      Parameters:
      directory - the directory to set
      Throws:
      NullPointerException - if directory is null

    • getNumaNode

      public int getNumaNode()
      Returns the NUMA node the persistent memory mounted to the given directory is attached to.
      Returns:
      the NUMA node of the persistent memory

    • setNumaNode

      public void setNumaNode(int numaNode)
      Sets the NUMA node the persistent memory mounted to the given directory is attached to.

      Note that setting numaNode to -1 on any of the configured PersistentMemoryDirectoryConfig instances disables NUMA-aware persistent memory allocation.

      Parameters:
      numaNode - the NUMA node to set

    • isNumaNodeSet

      public boolean isNumaNodeSet()
      Returns if the NUMA node for the given persistent memory directory is set.
      Returns:
      true if the NUMA node is set, false otherwise
