构造器详细资料

ExpandableBuffer

public ExpandableBuffer(int buffersize,
                ByteBufferAllocator allocator)

Allocates buffer of the given size using the given allocator.

参数:

buffersize - the buffer size.

allocator - allocator to be used to allocate ByteBuffers.

方法详细资料

getMode

protected int getMode()

Returns the current mode:

INPUT_MODE: the buffer is in the input mode.

OUTPUT_MODE: the buffer is in the output mode.

返回:

current input/output mode.

setOutputMode

protected void setOutputMode()

Sets output mode. The buffer can now be read from.

setInputMode

protected void setInputMode()

Sets input mode. The buffer can now be written into.

expand

protected void expand()

Expands buffer's capacity.

ensureCapacity

protected void ensureCapacity(int requiredCapacity)

Ensures the buffer can accommodate the required capacity.

capacity

public int capacity()

Returns the total capacity of this buffer.

指定者:

capacity 在接口中 BufferInfo

返回:

total capacity.

hasData

public boolean hasData()

Determines if the buffer contains data.

返回:

true if there is data in the buffer, false otherwise.

length

public int length()

Returns the length of this buffer.

指定者:

length 在接口中 BufferInfo

返回:

buffer length.

available

public int available()

Returns available capacity of this buffer.

指定者:

available 在接口中 BufferInfo

返回:

buffer length.

clear

protected void clear()

Clears buffer.

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object
