Class IOContext

  • public class IOContext
extends Object
    To limit number of configuration and state objects to pass, all contextual objects that need to be passed by the factory to readers and writers are combined under this object. One instance is created for each reader and writer.

    NOTE: non-final since 2.4, to allow sub-classing.

      • allocReadIOBuffer

        public byte[] allocReadIOBuffer()
        Method for recycling or allocation byte buffer of "read I/O" type.

        Note: the method can only be called once during its life cycle. This is to protect against accidental sharing.

        Returns:
        Allocated or recycled byte buffer

      • allocReadIOBuffer

        public byte[] allocReadIOBuffer​(int minSize)
        Variant of allocReadIOBuffer() that specifies smallest acceptable buffer size.
        Parameters:
        minSize - Minimum size of the buffer to recycle or allocate
        Returns:
        Allocated or recycled byte buffer
        Since:
        2.4

      • allocWriteEncodingBuffer

        public byte[] allocWriteEncodingBuffer()
        Method for recycling or allocation byte buffer of "write encoding" type.

        Note: the method can only be called once during its life cycle. This is to protect against accidental sharing.

        Returns:
        Allocated or recycled byte buffer

      • allocWriteEncodingBuffer

        public byte[] allocWriteEncodingBuffer​(int minSize)
        Variant of allocWriteEncodingBuffer() that specifies smallest acceptable buffer size.
        Parameters:
        minSize - Minimum size of the buffer to recycle or allocate
        Returns:
        Allocated or recycled byte buffer
        Since:
        2.4

      • allocBase64Buffer

        public byte[] allocBase64Buffer()
        Method for recycling or allocation byte buffer of "base 64 encode/decode" type.

        Note: the method can only be called once during its life cycle. This is to protect against accidental sharing.

        Returns:
        Allocated or recycled byte buffer

      • allocBase64Buffer

        public byte[] allocBase64Buffer​(int minSize)
        Variant of allocBase64Buffer() that specifies smallest acceptable buffer size.
        Parameters:
        minSize - Minimum size of the buffer to recycle or allocate
        Returns:
        Allocated or recycled byte buffer
        Since:
        2.9
