                                                                                StructDef<T> nodeType,

get

public T get(Nd nd,
             long address)

put

public void put(Nd nd,
                long address,
                T target)

destruct

public void destruct(Nd nd,
                     long address)

Specified by:

destruct in interface IDestructableField

getRecordSize

public int getRecordSize()

Description copied from interface: IField

Returns the size of the field, in bytes.

Specified by:

getRecordSize in interface IField

hasReferences

public boolean hasReferences(Nd nd,
                             long address)

Description copied from interface: IRefCountedField

Returns true if this field knows of any remaining incoming references to this object. This is used by the implementation of FieldManyToOne to determine whether or not a refcounted object should be deleted after a reference is removed.

Implementations should return false if the refcount is 0 or true if the refcount is nonzero.

Specified by:

hasReferences in interface IRefCountedField

setFieldName

protected final void setFieldName(java.lang.String fieldName)

setOffset

public final void setOffset(int offset)

Description copied from interface: IField

Sets the field offset (bytes from the start of the struct). This is invoked some time after field construction, after the sizes of all preceeding fields are known.

Specified by:

setOffset in interface IField

getOffset

public final int getOffset()

Description copied from interface: IField

Returns the field offset, in bytes from the start of the struct.

Specified by:

getOffset in interface IField

getFieldName

public final java.lang.String getFieldName()

Description copied from interface: IField

Returns the name of the field. This is mainly used for error messages, debug output, and diagnostic tools. Meant to be programmer-readable but not user-readable.

Specified by:

getFieldName in interface IField
