Method Detail

writeBoolean
```
void writeBoolean(boolean value)
```

writeChar
```
void writeChar(char value)
```

writeInt
```
void writeInt(int value)
```

writeLong
```
void writeLong(long value)
```

writeFloat
```
void writeFloat(float value)
```

writeDouble
```
void writeDouble(double value)
```

writeString

void writeString(java.lang.CharSequence value)

setArrayLength
```
void setArrayLength(int len)
```
Set length of the array. It must be called prior to nextWritableElement

Parameters:

len - length of the array

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

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);
  }
 
```
Returns:

reference to WritableValue object

Throws:

java.util.NoSuchElementException - when when the next element lays beyond array boundary

getFieldEncoder

UnboundEncoder getFieldEncoder(RecordClassDescriptor rcd)

writeBinary

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

writeNull
```
void writeNull()
```
