Field Detail

FIELDS

public static final List<String> FIELDS

cbBuffer

public int cbBuffer

Specifies the size, in bytes, of the buffer pointed to by the pvBuffer member.

BufferType

public int BufferType

Bit flags that indicate the type of buffer. Must be one of the values of the SecBufferType enumeration.

pvBuffer

public Pointer pvBuffer

A pointer to a buffer.

Constructor Detail

SecBuffer

public SecBuffer()

Create a new SECBUFFER_EMPTY buffer.

SecBuffer

public SecBuffer(int type,
                 int size)

Create a SecBuffer of a given type and size.

Parameters:

type - Buffer type, one of SECBUFFER_EMTPY, etc.

size - Buffer size, eg. MAX_TOKEN_SIZE.

SecBuffer

public SecBuffer(int type,
                 byte[] token)

Create a SecBuffer of a given type with initial data.

Parameters:

type - Buffer type, one of SECBUFFER_EMTPY, etc.

token - Existing token.

Method Detail

getBytes

public byte[] getBytes()

Get buffer bytes.

Returns:

Raw buffer bytes.

getFieldOrder

protected List<String> getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Overrides:

getFieldOrder in class Structure

Returns:

ordered list of field names
