Class MachineDataInfo

java.lang.Object
com.jogamp.common.os.MachineDataInfo
public class MachineDataInfo extends Object
Machine data description for alignment and size onle, see com.jogamp.gluegen.

little-endian / big/endian description is left, allowing re-using instances in StaticConfig. Use {@link {@link PlatformPropsImpl#LITTLE_ENDIAN}.

Further more, the value {@ MachineDataInfo#pageSizeInBytes} shall be ignored in StaticConfig, see compatible(MachineDataInfo).

    • equals

      public final boolean equals(Object obj)
      Checks whether two size objects are equal. Two instances of MachineDataInfo are considered equal if all components match but runtimeValidated, isRuntimeValidated().
      Overrides:
      equals in class Object
      Returns:
      true if the two MachineDataInfo are equal; otherwise false.

    • compatible

      Checks whether two MachineDataInfo objects are equal.

      Two MachineDataInfo instances are considered equal if all components match but isRuntimeValidated() and pageSizeInBytes().

      Returns:
      true if the two MachineDataInfo are equal; otherwise false.

    • toString

      public StringBuilder toString(StringBuilder sb)

    • toString

      public String toString()
      Overrides:
      toString in class Object
