Method Detail

beginWrite

public void beginWrite(deltix.util.memory.MemoryDataOutput out)

Specified by:

beginWrite in interface FixedUnboundEncoder

endWrite

public void endWrite()

Description copied from interface: UnboundEncoder

Checks that NOT NULLABLE restriction was not violated (Optional).

Specified by:

endWrite in interface UnboundEncoder

getClassInfo

public RecordClassInfo getClassInfo()

Specified by:

getClassInfo in interface FixedCodec

nextField

public boolean nextField()

Specified by:

nextField in interface UnboundEncoder

getField

public NonStaticFieldInfo getField()

Specified by:

getField in interface UnboundEncoder

writeBoolean

public void writeBoolean(boolean value)

Specified by:

writeBoolean in interface WritableValue

writeChar

public void writeChar(char value)

Specified by:

writeChar in interface WritableValue

writeInt

public void writeInt(int value)

Specified by:

writeInt in interface WritableValue

writeLong

public void writeLong(long value)

Specified by:

writeLong in interface WritableValue

writeFloat

public void writeFloat(float value)

Specified by:

writeFloat in interface WritableValue

writeDouble

public void writeDouble(double value)

Specified by:

writeDouble in interface WritableValue

writeString

public void writeString(java.lang.CharSequence value)

Specified by:

writeString in interface WritableValue

setArrayLength

public void setArrayLength(int len)

Description copied from interface: WritableValue

Set length of the array. It must be called prior to nextWritableElement

Specified by:

setArrayLength in interface WritableValue

Parameters:

len - length of the array

nextWritableElement

public WritableValue nextWritableElement()

Description copied from interface: WritableValue

Returns a transient (reused by interface implementation) WritableValue object for the next element of the array.

WritableValue.setArrayLength(int) method must be called before this method.
Client code must not cache the reference for further usage.
Usage sample:

  encoder.setArrayLength(10);
  for(int i=0; i<10; i++) {
      WritableValue v = encoder.nextWritableElement (i);
      v.setInt(i);
  }
 

Specified by:

nextWritableElement in interface WritableValue

Returns:

reference to WritableValue object

getFieldEncoder

public UnboundEncoder getFieldEncoder(RecordClassDescriptor rcd)

Specified by:

getFieldEncoder in interface WritableValue

writeBinary

public void writeBinary(byte[] data,
                        int offset,
                        int length)

Specified by:

writeBinary in interface WritableValue

writeNull

public void writeNull()

Specified by:

writeNull in interface WritableValue
