Constructor Details

GridUnsafeDataInput

public GridUnsafeDataInput()

Creates a new input with auto-shrinking disabled and no internal buffer assigned.

GridUnsafeDataInput

public GridUnsafeDataInput(long shrinkCheckFrequencyMs)

Creates a new input with no internal buffer assigned.

Parameters:

shrinkCheckFrequencyMs - how often to check whether an underlying byte buffer needs to be shrunk (disables the auto-shrinking if it's -1)

GridUnsafeDataInput

public GridUnsafeDataInput(byte[] bytes)

Creates a new input with auto-shrinking disabled.

Parameters:

bytes - array to initially (before automatic resize) use as an internal buffer

GridUnsafeDataInput

public GridUnsafeDataInput(byte[] bytes,
 long shrinkCheckFrequencyMs)

Creates a new input.

Parameters:

bytes - array to initially (before automatic resize) use as an internal buffer

shrinkCheckFrequencyMs - how often to check whether an underlying byte buffer needs to be shrunk (disables the auto-shrinking if it's -1)
