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 PlatformPropsImpl#LITTLE_ENDIAN}.

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

pageSizeInBytes

public final int pageSizeInBytes()

intAlignmentInBytes

public final int intAlignmentInBytes()

longAlignmentInBytes

public final int longAlignmentInBytes()

int8AlignmentInBytes

pageCount

public int pageCount(int size)

Returns:

number of pages required for size in bytes

pageAlignedSize

public int pageAlignedSize(int size)

Returns:

page aligned size in bytes

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

public final boolean compatible(MachineDataInfo md)

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
