ForwardBytesReader

public ForwardBytesReader(byte[] bytes)

Method Details

readByte

public byte readByte()

Description copied from class: DataInput

Reads and returns a single byte.

Specified by:

readByte in class DataInput

See Also:

• DataOutput.writeByte(byte)

readBytes

public void readBytes(byte[] b,
 int offset,
 int len)

Description copied from class: DataInput

Reads a specified number of bytes into an array at the specified offset.

Specified by:

readBytes in class DataInput

Parameters:

b - the array to read bytes into

offset - the offset in the array to start storing bytes

len - the number of bytes to read

See Also:

• DataOutput.writeBytes(byte[],int)

skipBytes

public void skipBytes(long count)

Description copied from class: DataInput

Skip over numBytes bytes. This method may skip bytes in whatever way is most optimal, and may not have the same behavior as reading the skipped bytes. In general, negative numBytes are not supported.

Specified by:

skipBytes in class DataInput

getPosition

public long getPosition()

Description copied from class: FST.BytesReader

Get current read position.

Specified by:

getPosition in class FST.BytesReader

setPosition

public void setPosition(long pos)

Description copied from class: FST.BytesReader

Set current read position.

Specified by:

setPosition in class FST.BytesReader
