Method Details

writeByte

public void writeByte(byte b)
               throws IOException

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 class DataOutput

Throws:

IOException

See Also:

• DataInput.readByte()

writeBytes

public void writeBytes(byte[] b,
 int length)
                throws IOException

Description copied from class: DataOutput

Writes an array of bytes.

Overrides:

writeBytes in class DataOutput

Parameters:

b - the bytes to write

length - the number of bytes to write

Throws:

IOException

See Also:

• DataInput.readBytes(byte[],int,int)

writeBytes

public void writeBytes(byte[] b,
 int offset,
 int length)
                throws IOException

Description copied from class: DataOutput

Writes an array of bytes.

Specified by:

writeBytes in class DataOutput

Parameters:

b - the bytes to write

offset - the offset in the byte array

length - the number of bytes to write

Throws:

IOException

See Also:

• DataInput.readBytes(byte[],int,int)

writeInt

public void writeInt(int i)
              throws IOException

Description copied from class: DataOutput

Writes an int as four bytes (LE byte order).

Overrides:

writeInt in class DataOutput

Throws:

IOException

See Also:

• DataInput.readInt()
• BitUtil.VH_LE_INT

writeShort

public void writeShort(short i)
                throws IOException

Description copied from class: DataOutput

Writes a short as two bytes (LE byte order).

Overrides:

writeShort in class DataOutput

Throws:

IOException

See Also:

• DataInput.readShort()
• BitUtil.VH_LE_SHORT

writeLong

public void writeLong(long i)
               throws IOException

Description copied from class: DataOutput

Writes a long as eight bytes (LE byte order).

Overrides:

writeLong in class DataOutput

Throws:

IOException

See Also:

• DataInput.readLong()
• BitUtil.VH_LE_LONG

writeString

public void writeString(String s)
                 throws IOException

Description copied from class: DataOutput

Writes a string.

Writes strings as UTF-8 encoded bytes. First the length, in bytes, is written as a VInt, followed by the bytes.

Overrides:

writeString in class DataOutput

Throws:

IOException

See Also:

• DataInput.readString()

copyBytes

public void copyBytes(DataInput input,
 long numBytes)
               throws IOException

Description copied from class: DataOutput

Copy numBytes bytes from input to ourself.

Overrides:

copyBytes in class DataOutput

Throws:

IOException

writeMapOfStrings

public void writeMapOfStrings(Map<String,String> map)
                       throws IOException

Description copied from class: DataOutput

Writes a String map.

First the size is written as an vInt, followed by each key-value pair written as two consecutive Strings.

Overrides:

writeMapOfStrings in class DataOutput

Parameters:

map - Input map.

Throws:

IOException

writeSetOfStrings

public void writeSetOfStrings(Set<String> set)
                       throws IOException

Description copied from class: DataOutput

Writes a String set.

First the size is written as an vInt, followed by each value written as a String.

Overrides:

writeSetOfStrings in class DataOutput

Parameters:

set - Input set.

Throws:

IOException
