Class Buffer

Namespace

easyar

Assembly

EasyAR.Sense.dll

Buffer stores a raw byte array, which can be used to access image data. In the Java API, you can get the buffer from Image_ and then copy the data to a Java byte array. In all versions of EasyAR Sense, you can access the image data. Refer to Image_.

Methods

Clone()

public Buffer Clone()

Returns

CloneObject()

protected override object CloneObject()

Returns

copyFromByteArray(byte[])

public void copyFromByteArray(byte[] src)

Parameters

src

copyFromByteArray(byte[], int, int, int)

public void copyFromByteArray(byte[] src, int srcIndex, int index, int length)

Parameters

src

srcIndex

index

length

copyToByteArray(byte[])

public void copyToByteArray(byte[] dest)

Parameters

dest

copyToByteArray(int, byte[], int, int)

public void copyToByteArray(int index, byte[] dest, int destIndex, int length)

Parameters

index

dest

destIndex

length

create(int)

Creates a Buffer with a specified byte length.

public static Buffer create(int size)

Parameters

size

Returns

data()

Returns the raw memory address.

public virtual IntPtr data()

Returns

memoryCopy(IntPtr, IntPtr, int)

Copies raw memory. Mainly used in languages or environments with incomplete memory operations.

public static void memoryCopy(IntPtr src, IntPtr dest, int length)

Parameters

src

dest

length

partition(int, int)

Creates a sub-Buffer and references the original Buffer. A Buffer is released only after all sub-Buffers are released.

public virtual Buffer partition(int index, int length)

Parameters

index

length

Returns

size()

The byte length of the Buffer.

public virtual int size()

Returns

tryCopyFrom(IntPtr, int, int, int)

Attempts to copy data from the raw memory address to the Buffer. Returns true if the copy is successful, otherwise returns false. The reasons for failure are: the source data range or the target data range exceeds the available range.

public virtual bool tryCopyFrom(IntPtr src, int srcIndex, int index, int length)

Parameters

src

srcIndex

index

length

Returns

tryCopyTo(int, IntPtr, int, int)

Attempts to copy data from the Buffer to the raw memory address. Returns true if the copy is successful, otherwise returns false. The reasons for failure are: the source data range or the target data range exceeds the available range.

public virtual bool tryCopyTo(int index, IntPtr dest, int destIndex, int length)

Parameters

index

dest

destIndex

length

Returns

wrap(IntPtr, int, Action)

Wraps a raw memory block of a specified length. When the Buffer is completely released, the deleter callback is called to perform user-defined memory destruction behavior. The deleter must be thread-safe.

public static Buffer wrap(IntPtr ptr, int size, Action deleter)

Parameters

ptr

size

deleter

Returns

wrapByteArray(byte[])

public static Buffer wrapByteArray(byte[] bytes)

Parameters

bytes

Returns

wrapByteArray(byte[], int, int)

public static Buffer wrapByteArray(byte[] bytes, int index, int length)

Parameters

bytes

index

length

Returns

wrapByteArray(byte[], int, int, Action)

public static Buffer wrapByteArray(byte[] bytes, int index, int length, Action deleter)

Parameters

bytes

index

length

deleter

Returns
