Constructor Detail

StructIO

public StructIO(Class<?> structClass,
        Type structType)

Method Detail

getInstance

public static StructIO getInstance(Type structType)

getInstance

public static StructIO getInstance(Class structClass,
                   Type structType)

registerStructIO

public static StructIO registerStructIO(Class structClass,
                        Type structType,
                        StructIO io)

toString

public String toString()

Overrides:

toString in class Object

equal

public boolean equal(StructObject a,
            StructObject b)

compare

public int compare(StructObject a,
          StructObject b)

describe

public final String describe(StructObject struct)

writeFieldsToNative

public final void writeFieldsToNative(StructObject struct)

Write struct fields implemented as Java fields to the corresponding native memory (Java fields are written to native memory).
This does not concern normal structs as generated by JNAerator (which use getters and setters methods that read and write the fields directly from / to the native memory), but rather structs that are in the JNA style.

readFieldsFromNative

public final void readFieldsFromNative(StructObject struct)

Read struct fields implemented as Java fields from the corresponding native memory (Java fields are read from native memory).
This does not concern normal structs as generated by JNAerator (which use getters and setters methods that read and write the fields directly from / to the native memory), but rather structs that are in the JNA style.
