Method Detail

write

public void write(byte[] buffer,
         int offset,
         int count)

Description copied from class: AbstractDataOutput

Writes count bytes from the byte array buffer starting at offset to this RandomAccessFile starting at the current file pointer..

Specified by:

write in interface java.io.DataOutput

Specified by:

write in class AbstractDataOutput

Parameters:

buffer - the bytes to be written

offset - offset in buffer to get bytes

count - number of bytes in buffer to write

write

public void write(int oneByte)

Description copied from class: AbstractDataOutput

Writes the specified byte oneByte to this RandomAccessFile starting at the current file pointer. Only the low order byte of oneByte is written.

Specified by:

write in interface java.io.DataOutput

Specified by:

write in class AbstractDataOutput

Parameters:

oneByte - the byte to be written

writeShort

public void writeShort(int val)
                throws java.io.IOException

Description copied from class: AbstractDataOutput

Writes the specified 16-bit short to the OutputStream. Only the lower 2 bytes are written with the higher of the 2 bytes written first.

Specified by:

writeShort in interface java.io.DataOutput

Overrides:

writeShort in class AbstractDataOutput

Parameters:

val - the short to be written

Throws:

java.io.IOException - If an error occurs attempting to write to this DataOutputStream.

writeInt

public void writeInt(int val)

Description copied from class: AbstractDataOutput

Writes a 32-bit int to this output stream. The resulting output is the 4 bytes, highest order first, of val.

Specified by:

writeInt in interface java.io.DataOutput

Overrides:

writeInt in class AbstractDataOutput

Parameters:

val - the int to be written.

writeLong

public void writeLong(long val)

Description copied from class: AbstractDataOutput

Writes a 64-bit long to this output stream. The resulting output is the 8 bytes, highest order first, of val.

Specified by:

writeLong in interface java.io.DataOutput

Overrides:

writeLong in class AbstractDataOutput

Parameters:

val - the long to be written.

write

public void write(java.nio.ByteBuffer buffer)

Specified by:

write in interface DataOutputPlus

Overrides:

write in class AbstractDataOutput

write

public void write(Memory memory)

currentBuffer

public SafeMemory currentBuffer()

setCapacity

public void setCapacity(long newCapacity)

close

public void close()

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.OutputStream

length

public long length()

capacity

public long capacity()

withByteOrder
