true if all values are validated at runtime, otherwise false (i.e. for static compilation w/ preset values)

isLittleEndian

public final boolean isLittleEndian()

Returns true only if this system uses little endian byte ordering.

is32Bit

public final boolean is32Bit()

Returns true if this JVM/ARCH is 32bit.

is64Bit

public final boolean is64Bit()

Returns true if this JVM/ARCH is 64bit.

equals

public final boolean equals(Object obj)

Checks whether two size objects are equal. Two instances of MachineDescription are considered equal if all components match but runtimeValidated, isRuntimeValidated().

Overrides:

equals in class Object

Returns:

true if the two MachineDescription are equal; otherwise false.

compatible

public final boolean compatible(MachineDescription md)

Checks whether two size objects are equal. Two instances of MachineDescription are considered equal if all components match but isRuntimeValidated() and pageSizeInBytes().

Returns:

true if the two MachineDescription are equal; otherwise false.

toString

public StringBuilder toString(StringBuilder sb)

toString

public String toString()

Overrides:

toString in class Object
