Method Detail

open

public RawFileOperationSupport.RawFileDescriptor open(String filename,
                                                      RawFileOperationSupport.FileAccessMode mode)

Description copied from interface: RawFileOperationSupport

Opens or creates a file with the specified access mode.

Specified by:

open in interface RawFileOperationSupport

Returns:

If the operation is successful, it returns the file descriptor. Otherwise, it returns a value where RawFileOperationSupport.isValid(com.oracle.svm.core.os.RawFileOperationSupport.RawFileDescriptor) will return false.

write

public boolean write(RawFileOperationSupport.RawFileDescriptor fd,
                     byte[] data)

Description copied from interface: RawFileOperationSupport

Writes data to the current file position and advances the file position.

Specified by:

write in interface RawFileOperationSupport

Returns:

true if the data was written, false otherwise.

writeBoolean

public boolean writeBoolean(RawFileOperationSupport.RawFileDescriptor fd,
                            boolean data)

Description copied from interface: RawFileOperationSupport

Writes data to the current file position and advances the file position.

Specified by:

writeBoolean in interface RawFileOperationSupport

Returns:

true if the data was written, false otherwise.

writeByte

public boolean writeByte(RawFileOperationSupport.RawFileDescriptor fd,
                         byte data)

Description copied from interface: RawFileOperationSupport

Writes data to the current file position and advances the file position.

Specified by:

writeByte in interface RawFileOperationSupport

Returns:

true if the data was written, false otherwise.

writeShort

public boolean writeShort(RawFileOperationSupport.RawFileDescriptor fd,
                          short data)

Description copied from interface: RawFileOperationSupport

Writes a short value in the specified byte ordering to the current file position and advances the file position.

Specified by:

writeShort in interface RawFileOperationSupport

Returns:

true if the data was written, false otherwise.

                         char data)

Description copied from interface: RawFileOperationSupport

Writes a char value in the specified byte ordering to the current file position and advances the file position.

Specified by:

writeChar in interface RawFileOperationSupport

Returns:

true if the data was written, false otherwise.

writeInt

public boolean writeInt(RawFileOperationSupport.RawFileDescriptor fd,
                        int data)

Description copied from interface: RawFileOperationSupport

Writes an integer value in the specified byte ordering to the current file position and advances the file position.

Specified by:

writeInt in interface RawFileOperationSupport

Returns:

true if the data was written, false otherwise.

writeLong

public boolean writeLong(RawFileOperationSupport.RawFileDescriptor fd,
                         long data)
