writeByte
public void writeByte(byte b) Description copied from class:DataOutput
Writes a single byte.The most primitive data type is an eight-bit byte. Files are accessed as sequences of bytes. All other data types are defined as sequences of bytes, so file formats are byte-order independent.
- Specified by:
writeByte
in classDataOutput

writeBytes
public void writeBytes(byte[] b, int offset, int length) Description copied from class:DataOutput
Writes an array of bytes.- Specified by:
writeBytes
in classDataOutput
- Parameters:
b
- the bytes to writeoffset
- the offset in the byte arraylength
- the number of bytes to write- See Also:
-
ramBytesUsed
public long ramBytesUsed()Description copied from interface:Accountable
Return the memory usage of this object in bytes. Negative values are illegal.- Specified by:

getReverseBytesReader
Description copied from interface:FSTReader
Get the reverse BytesReader for this FST- Specified by:
getReverseBytesReader
in interfaceFSTReader
- Returns:
- the reverse BytesReader
-
writeTo
Description copied from interface:FSTReader
Write this FST to another DataOutput- Specified by:
writeTo
in interfaceFSTReader
- Parameters:
