Interface BERTLVFileView

All Superinterfaces:

FileView, javacard.framework.Shareable

All Known Subinterfaces:

AdminBERTLVFileView

public interface BERTLVFileView
extends FileView

The BERTLVFileView interface defines the methods to access BER TLV files.
All the methods are based on the commands of the TS 102 221 specification.

Method Summary

void	deleteData(int tag) This method deletes a data object in the current BER-TLV structure EF.
int	getTAGList(byte mode, int[] responseBuffer, short responseOffset, short responseLength) This method gets the list of TAGs already allocated in the current BER-TLV structure EF.
int	retrieveData(int tag, int dataObjectOffset, byte[] responseBuffer, short responseOffset, short responseLength) This method retrieves a part of a data object from the current BER-TLV structure EF.
int	setData(int tag, byte mode, int dataLength, byte[] data, short offset, short length) This method sets a data object in the current BER-TLV structure EF.

Method Detail

retrieveData

int retrieveData(int tag,
                 int dataObjectOffset,
                 byte[] responseBuffer,
                 short responseOffset,
                 short responseLength)

This method retrieves a part of a data object from the current BER-TLV structure EF.

Notes:

• The TAG and Length of the requested data object are not copied in responseBuffer
• After a successful call to this method, current TAG pointer and current offset in the data object are undefined
• If responseOffset or responseLength parameter is negative an ArrayIndexOutOfBoundsException exception is thrown.
• If responseOffset+responseLength is greater than responseBuffer.length, the length of the responseBuffer array a ArrayIndexOutOfBoundsException exception is thrown and no read is performed.
• If tag value is invalid or is equal to '5C', an UICCException with reason code INVALID_TAG_VALUE is thrown

Parameters:

tag - is the TAG value of TLV object that shall be retrieved.

dataObjectOffset - is the offset in the data object.

responseBuffer - is the reference to the response byte array for read data.

responseOffset - is the offset in the response byte array.

responseLength - is the number of bytes to read.

Returns:

Number of remaining bytes to read

Throws:

java.lang.NullPointerException - if responseBuffer is null

java.lang.ArrayIndexOutOfBoundsException - if reading would cause access of data outside array bounds

UICCException - in case of error

• INTERNAL_ERROR
• COMMAND_INCOMPATIBLE
• SECURITY_STATUS_NOT_SATISFIED
• REF_DATA_INVALIDATED
• NO_EF_SELECTED
• REFERENCED_DATA_NOT_FOUND
• CONDITIONS_OF_USE_NOT_SATISFIED
• OUT_OF_DATA_BOUNDARIES
• INVALID_TAG_VALUE

getTAGList

int getTAGList(byte mode,
               int[] responseBuffer,
               short responseOffset,
               short responseLength)

This method gets the list of TAGs already allocated in the current BER-TLV structure EF.

Notes:

• After a successful call to this method, current TAG pointer and current offset in the data object are undefined
• If responseOffset or responseLength parameter is negative an ArrayIndexOutOfBoundsException exception is thrown.
• If responseOffset+responseLength is greater than responseBuffer.length, the length of the responseBuffer array a ArrayIndexOutOfBoundsException exception is thrown and no operation is performed.

Parameters:

mode - is the mode to be used (UICCConstants.BER_TLV_ACC_MODE_FIRST or UICCConstants.BER_TLV_ACC_MODE_NEXT)

responseBuffer - is the reference to the response int array for read data. Each component of the responseBufferarray contains a single TAG.

responseOffset - is the offset in the response int array.

responseLength - is the number of TAGs to read.

Returns:

Number of remaining TAGs to read

Throws:

java.lang.NullPointerException - if responseBuffer is null

java.lang.ArrayIndexOutOfBoundsException - if reading would cause access of data outside array bounds

UICCException - in case of error

• INTERNAL_ERROR
• COMMAND_INCOMPATIBLE
• SECURITY_STATUS_NOT_SATISFIED
• REF_DATA_INVALIDATED
• NO_EF_SELECTED
• INVALID_MODE
• CONDITIONS_OF_USE_NOT_SATISFIED
• OUT_OF_DATA_BOUNDARIES

setData

int setData(int tag,
            byte mode,
            int dataLength,
            byte[] data,
            short offset,
            short length)

This method sets a data object in the current BER-TLV structure EF.

Notes:

• A transfer ends immediately after the end of the data object is reached (last successful call to this method).
• As long as the transfer is not complete, the data object is not available for other entities.
• If offset or length parameter is negative an ArrayIndexOutOfBoundsException exception is thrown.
• If offset+length is greater than data.length, the length of the data array a ArrayIndexOutOfBoundsException exception is thrown and no update is performed.
• If mode is BER_TLV_ACC_MODE_FIRST and dataLength is equal to 0, a zero length object is created.
• If tag value is invalid or is equal to '5C', an UICCException with reason code INVALID_TAG_VALUE is thrown

Parameters:

tag - is the TAG value of TLV object that shall be set. The value is not significant if code>mode parameter is set to UICCConstants.BER_TLV_ACC_MODE_NEXT.

mode - is the mode to be used (UICCConstants.BER_TLV_ACC_MODE_FIRST or UICCConstants.BER_TLV_ACC_MODE_NEXT)

dataLength - is the length of the value field of the BER-TLV data object. The value is not significant if mode parameter is set to UICCConstants.BER_TLV_ACC_MODE_NEXT.

data - is the reference to the data byte array.

offset - is the offset in the data byte array.

length - is the number of bytes to set.

Returns:

Number of remaining bytes to set

Throws:

java.lang.NullPointerException - if responseBuffer is null

java.lang.ArrayIndexOutOfBoundsException - if reading would cause access of data outside array bounds

UICCException - in case of error

• INTERNAL_ERROR
• COMMAND_INCOMPATIBLE
• SECURITY_STATUS_NOT_SATISFIED
• NO_EF_SELECTED
• INVALID_MODE
• MEMORY_PROBLEM
• REFERENCED_DATA_NOT_FOUND
• NOT_ENOUGH_MEMORY_SPACE
• CONDITIONS_OF_USE_NOT_SATISFIED
• OUT_OF_DATA_BOUNDARIES
• INVALID_TAG_VALUE
