                        int length)
                 throws java.io.IOException

Description copied from class: ByteOutput

Writes a sequence of bytes. The ByteOutput must copy value if it will not be processed prior to the return of this method call, since value may be reused/altered by the caller.

NOTE: This method MUST NOT modify the value. Doing so is a programming error and will lead to data corruption which will be difficult to debug.

Specified by:

write in class CodedOutputStream

Parameters:

value - the bytes to be written

offset - the offset of the start of the writable range

length - the number of bytes to write starting from offset

Throws:

java.io.IOException - thrown if an error occurred while writing

writeLazy

public final void writeLazy(byte[] value,

                            int length)
                     throws java.io.IOException

Description copied from class: ByteOutput

Writes a sequence of bytes. The ByteOutput is free to retain a reference to the value beyond the scope of this method call (e.g. write later) since it is considered immutable and is guaranteed not to change by the caller.

NOTE: This method MUST NOT modify the value. Doing so is a programming error and will lead to data corruption which will be difficult to debug.

Specified by:

writeLazy in class CodedOutputStream

Parameters:

value - the bytes to be written

offset - the offset of the start of the writable range

length - the number of bytes to write starting from offset

Throws:

java.io.IOException - thrown if an error occurred while writing

write

public final void write(java.nio.ByteBuffer value)
                 throws java.io.IOException

Description copied from class: ByteOutput

Writes a sequence of bytes. The ByteOutput must copy value if it will not be processed prior to the return of this method call, since value may be reused/altered by the caller.

NOTE: This method MUST NOT modify the value. Doing so is a programming error and will lead to data corruption which will be difficult to debug.

Specified by:

write in class CodedOutputStream

Parameters:

value - the bytes to be written. Upon returning from this call, the position of this buffer will be set to the limit

Throws:

java.io.IOException - thrown if an error occurred while writing

writeLazy

public final void writeLazy(java.nio.ByteBuffer value)
                     throws java.io.IOException

Description copied from class: ByteOutput

Writes a sequence of bytes. The ByteOutput is free to retain a reference to the value beyond the scope of this method call (e.g. write later) since it is considered immutable and is guaranteed not to change by the caller.

NOTE: This method MUST NOT modify the value. Doing so is a programming error and will lead to data corruption which will be difficult to debug.

Specified by:

writeLazy in class CodedOutputStream

Parameters:

value - the bytes to be written. Upon returning from this call, the position of this buffer will be set to the limit

Throws:

Specified by:

writeStringNoTag in class CodedOutputStream

flush

public void flush()

Description copied from class: CodedOutputStream

Specified by:

flush in class CodedOutputStream

spaceLeft

public final int spaceLeft()

Description copied from class: CodedOutputStream

If writing to a flat array, return the space left in the array. Otherwise, throws UnsupportedOperationException.
